The idea is to seal up the little grooves, which the brush can't reach. Here is a brush bristle that can't reach down into that really small groove on a molar. Fluoride helps prevent decay as well by strengthening the enamel. Fluoride seems to work best, however, on the smooth surfaces of the teeth. Sealants are for the grooves, so you usually don't use them on front teeth for instance.
They are really easy to do. You just sort of paint it on (well, there are several steps, but still fairly easy like using a fiberoptic "flash light") The only thing that can make it harder is if the child has a small mouth or a gag reflex or a wiggly tongue that makes it hard to get back there and keep things dry.
If sealed well, the "cavity bugs" can't get down in there. Sealants last several years and may need to be patched or replaced from time to time. If the kid doesn't chew ice or stuff like that, they will hold up fairly well. If they chip or come off, the "Bugs" can get back in there. My kids have sealants and have never had a cavity!Here is another post I made on the same subject:
The American Academy of Pediatric Dentistry recommends placing dental sealants on the first permanent molars (at around 6 years of age) and the second permanent molars (which come in around 12 years of age).
Why? --Well, basically there are a lot of studies that say placing sealants helps reduce the incidence of cavities. Does it mean you will never get cavities?--no, it still can happen, but sealants can reduce the kind of cavities that form in the pits and grooves of the back teeth, you know on the top of the tooth--you still can get them in between the teeth and on the smooth surfaces.
How long do they last?--Even with a well placed sealant I have seen cavities form in areas previously sealed. Sometimes the sealant wears off (chewing ice for instance), or sometimes just because someone is very prone to cavities. They say they last from 5 to 7 years if you take care of them--even adults can get sealants, but they seem to be most effective in the cavity prone years of youth. What is the material? Well, it's basically the same material as used in white fillings without as much filler/reinforcing material, it's a bis-GMA resin, With less filler the sealant can flow into the grooves better. Sometimes we use "flowable" composite which is kind of in between in it's characteristics.
How are they placed? Does it hurt?--I like to say it's like painting fingernails--you basically just paint it on the tooth--now that can be harder than you think as these teeth are in the back of the mouth. Most of the effort is keeping the area dry.
Do you put them on baby teeth?--you can, but generally no. The enamel in baby teeth is different microscopically, they don't seem to stay as well, but sometimes if there is lots of grooves there, so there may be a benefit to placing them. Another thing to think about is that in preschoolers, placing a sealant is just about as difficult as a small filling because little kids, well it's harder to place the sealants. It is often better to simply have regular checkups to catch things early. Also, like I said many cavities in baby teeth are in between the teeth which sealants do not prevent.
I'm going to try and make a video on this some day.

Why do they have to put my 2-yr-old grandson under general to apply dental sealants? He is having it done @ Womens' and Childrens's Hospital in Bflo, NY. Is there anything we should know or ask beforehand?
many thanks, Sue Caferro

I do not put children under GA just for sealants as they are a preventive treatment. Now if there is justification due to other work needed like extensive restorations AND sealants, then I would take the opportunity to do them while the child is asleep.
My five year old has had eight cavities with four crowns put on earlier this year. She also had two lower back molars come in and they put dental sealants on during her hospital visit. I notice that her upper back molars are now coming in and would like to get sealants on these as well since she is cavity prone. How long does it take for a back molar to fully come in so I can get the sealants put on? I am worried to wait too long due to getting any more cavities. Can multiple sealants be done at one office visit?
Sealants can be done once the tooth erupts, usually about two months or so after it pops through--depends, sometimes can be longer than that. Check with your dentist.
Why would they put sealants on a 2-yr old?? Most dentists only recommend sealants on permanent teeth, meaning 6-yr molars or older.And general anesthesia is a little excessive. It is a very painless procedure.
My child is 3 1/2. Her dentist said she would need sealants on her back morlars because she has deep grooves. The office handed me a paper stating she was going to get nitrous oxide, a novacaine shot and 2 fillings. When I called to ask them what the fillings were about, they are saying she has cavaties. Why would the dentist tell me sealants not fillings? And tell me she dosen't have cavaties YET? I'm a confused and concerned. I don't think she should get nitrous oxide. Too much drugs for such a small body. Any advice?

-I cannot say what your dentist intends, but sounds like you have some sort of communication problem between what they said and what you heard or something like that. Sometimes the difference between the term "filling" and "sealant" can become blurred.
A sealant is a preventive covering placed when there is no cavity present to prevent decay. The material is very similar however, to that used in "fillings". A filling is decay that is removed leaving a hole to be filled with a material very much like a sealant.
The problem comes in when a tooth may have deep grooves, not a cavity necessarily but really deep grooves, once they are "cleaned out" sometimes with a bur just like in a filling procedure, there may be such a large groove or hole just in one spot that filling material may be placed instead of the sealant-or maybe a flowable composite which is a material that is used for both sealants and small fillings.
Is it a sealant? Is it a filling? Sort of a grey area there.
Thank you for your response. I spoke to her dentist and he said he won't know if her right molar has a cavity until he starts the process? And that insurance won't pay for the sealant, hence the fillings.
I'm even more confused.
He cleaned her teeth and he couldn't tell if she had a cavity on the right, but could tell on the left ... I'm going to look into another pediatric dentist ...
Yes, I have had situations where a tooth was initially planned as a sealant, but once the appointment was made some time later and the grooves were cleaned out as uaual, there was a deep groove. Then when that was cleaned out there was a bigger spot--eventually the cavity became large enough and more evident and was restored with filling material. Other times a cavity (carious lesion) is so shallow that I would place a sealant rather than a composite filling. Cavities can be very small on the surface but deeper down they can be much larger. Usually you can tell, but sometimes you cannot tell for sure until you begin a procedure.
Can you please tell me what the difference between sealing a tooth and placing a silver crown on it would be? I have a 3 1/2 year old who has to have work done on his molars and they wanted to do silver crowns on all 8. He has cavities back there, so is this the common procedure for that or can they do sealants?
Sealants are only for teeth without cavities--Cavities must be restored with fillings/crowns etc. Sealants are a preventive measure.
Thank you so much for helping me earlier. You have no idea how wonderful this website has been for me as a first timer at this pediatric dental "stuff." My 3 1/2 year old son will be put under next Monday for stainless steel caps and a pulpotomy on his molars. He's starting to have a runny nose and coughing. He was initially cleared in his pre-op exam, but now I'm nervous that this may affect his anesthesia. Is this normally a concern?
We always follow a protocol for general anesthesia cases. The kids must see a physician to have a health and physical a day or two before the procedure. If kids get "sick" then cases should be postponed. If a child has a fever a chest cold, I would let the dentist know and any phyician involved so they can make a determination if it is a serious thing necessitating postponement or just a non consequential thing. Anesthesiologists also check out the kids just prior to the procedure just to make sure the kids are good to go.
My dentist put sealant on my two front teeth about 3 months ago because I have an overbite. Since having this done I have been back twice to have some of the sealant taken away because my teeth don't feel like there aligned properly. For the last month I have developed some mild pain in my right side of my jaw. I assumed it was something to do with the sealents but when my dentist examined my jaw he says that I have a mild dislocation to the jaw. Has the sealant caused this?
Sealants are not usually placed on front teeth, however, sometimes they are placed on the groove on the tongue side of the upper front teeth. Sealants, even if they are placed incorrectly or too thickly will wear down quickly with normal wear. So, no, I have never sen a sealant cause dislocation of the jaw.
My 4 year old just left the dentist and he said she has 2 cavities each on her back baby molars.. both surface very small I couldnt even see them but he could feel them with his pic... They want to fill them and use anesthesia? Is ok to wait or should I have this done now, seems like a lot for a four year old? Thanks!
Sedation is usually indicated if there is a certain level of anxiety, resistance or the concern dental work might elicit such a reaction. Read more on this blog about behavior management and sedation many 4 year olds do just fine.
I jus had a question. My dentist placed a sealant on my tooth and after telling me to bite down, said it might be too thick. He said wait a month and then if its still thick, will re do it. He buffed it down but i guess that wasn't enough. My question is how does the sealant thin out on its on? And by it being too thick is that more damaging to my tooth, is my tooth still even protected? Why a month? Couldn't he have redone it the same visit?
Hey, just sitting at my computer when your comment came through---Sealant material will wear down with time with no damage to any tooth structure. If it comes off in one big chunk, the protective effect might be reduced-so, might need a redo at some point. If it is really bothering you like it's really thick or high, smoothing it down can help.
Hi I was wondering what is the cost of the sealant if my insurance does not cover it
Hi I have a question. I was talking to a friend and she noticed I have silver filling in my teeth and informed me that they do not use silver anymore and if I go to the dentist they will replace them with the clear ones. I'm just wondering if this is true and if so does it depend on the type of insurnace I have? I also want to know if you get adult wisdom teeth removed do they put you to sleep or just numb the area and do it while awake. Does this also depend on my insurance?
Cost vary, but they generally are about a fourth or a third of what a small filling costs.
Anon,
You may want to read my post on White fillings:
White fillings vs. Silver fillings
Insurance status should not matter.
Wisdom teeth, well it depends. Most of the time oral surgeons will put you asleep. If they are already erupted and accessible, sometimes you can just numb up and remove like other teeth.
Oh, and here too:
Silver fillings
My 7 yr old has a cavity on her molar that is scheduled to be filled but her dentist also wants to put a sealant on top of the filling. My insurance will not cover a sealant when being placed over a filling. Is it necessary to have a sealant added with a filling? Thank you
Composite, or white tooth color fillings are the same material (well pretty much) as a sealant. Sealants are used to protect the parts of the tooth not filled by the actual filling material--usually a larger area. So putting a sealant "over" a filling is not a dental concern. Sometimes there is a small filling on one part of the tooth, say on the side of the tooth, but you also want to place a sealant on the occlusal or top part of the tooth at the same time. This is done often on the lower permanent molars. When insurance gets involved it can complicate things, meaning they just don't get it when you are talking two procedures even though both are of benefit. I'd just ask your dentist, what they are planning.
I'm 37 years old and I have never had a cavity. My grandfather was a dentist and sealed my adult teeth when I was a child and it has made all of the difference. We recently moved and found a new dentist. He looked at my last molar on the left side and thought it looked funny. Nothing came up in the X-ray but he's concern that the deep crack will form a cavity in the future. He says it's not a matter of if, but when. As a mother of three, he said my diet is probably not that great and I probably don't have time to really care for my teeth the way they need to be cared for, so this is a preventative measure. I brush daily and floss occasionally. I rarely eat sugar and have a highly nutritious diet. If I add ACT to my routine and start flossing daily, will I be in the clear? Or should I just get the filling and resign myself to my new situation?
My six year old has her bottom 6 year old molars. A few months ago I was told they had deep grooves but no cavities. I asked about sealants and was told she didn’t need them (but I also asked about the sealants “safety” as in plastics so he may have thought I didn’t want them). Now a few months later, they say she has sticky cavities (but very shallow) on these two teeth. My questions: Can a molar be sealed after a cavity is cleaned and filled? If they are indeed shallow would there be a benefit to waiting a month or two to see if they can “remineralize” or heal (at home use of xylitol, ACT rinses, etc). I read about possibly getting decay under the sealants and making the problem worse. I read that new teeth are soft and in need of hardening (xylitol, calcium, fluoride) and if so, would the sealant keep this from happening (which wouldn’t be a bad thing right?) Also, do you feel that I could have transmitted bacteria that cause cavities from my mouth to my child’s? I have had lots of cavities in my life (and I do tend to share water cups etc with her but now I am trying not to). Thank you in advance. I appreciate your input.
If a filling is a composite (white filling) whether it be shallow or large, well, it is its own sealant--it's the same material, so the tooth is sealed if it is filled. So, there is no additional benefit to sealing after a filling if it encompasses all the grooves. If there is a cavity--a carious process, I would not wait, it will progress. We only "wait and watch" areas that are suspicious, but not yet cavities. Those areas, yes, they might remineralize--those are usually the smooth surface areas, not the pit and fissure areas.
My almost 4 year old has 8 cavities all between her baby molars. One pediatric dentist recommended fillings and another pediatric dentist recommended silver crowns. So which is better?????? Please help me make a decision. I want what's best for my daughter. Thanks for your help.
Basically, it depends. Fillings are generally fine IF the cavity is minimal and there is little chance of future decay on the same tooth. Crowns are best for larger cavities--they hold up better. Here are several of my posts on things like this:
Dental Restorations, fillings, crowns, etc
My 12 month old has 4 cavities aka bottle rot from breastfeeding. His teeth look really bad. Should I get them crowned?
I would advise seeing a pediatric dentist. They can tell you if crowns are needed, or perps just fillings or some other option. Decay at such a young age will likely be aggressive, but the situation can be fixed.
My son dentist told me he needed two sealants.... When he was done I seen that hr put silver caps on my son teeth I'd that normal. I always thought that sealants were clear....MY son Also just had a checkup and everything was fine
My daughter is almost 7 and went in a couple months ago.. No cavities .. but they put a sealant on her teeth.. a week later the front bottom two ( permanent teeth) are turning black.. Is this normal, she hates it and brushes constantly?
Sealants are not usually placed on front teeth (top or bottom). -Sounds like stain, but talk with your dentist.
I have concerns about my daughter's dental care. For three years we were told she had perfect check ups no concerns and then 6 months later they tell me she needs a filling. They told me they had been watching it for a while, no one told me. Then another 6 months go by and they tell me she has two more tiny ones, again they had been watching, again no mention to me. We went in to have them filled and at the appointment they tell me they need to crown the one because it is so large. I was at a loss after just a week, it went from tiny to so large it needed a crown but no baby root canal. They already had the crown listed in her chart before this dentist saw it. Sorry I forget what a baby root canal is called, lol. She does not eat candy or drink soft drinks or sports drinks or koolaid. She wasn't bottle fed. She drinks milk water and very little juice. She has gone to the dentist every 6 months since a year or so old, and was even given flouride drops as a baby because we don't drink tap water. Our latest visit they wanted to seal her teeth and guess what, another surprise cavity on a newly erupted molar, only this time when we showed up for the appointment the next dentist said it was not a cavity but a sticky groove and she didn't fill it. What is a sticky groove? I am very concerned why one says cavity and one says not, and all of these surprises. This is a chain dentist office and I am concerned they are just making money off fillings. They tried to show these to me on x-ray but I could not see anything. Thanks in advance for your advice
Often, teeth have grooves. Sometimes these grooves get decay in them, other times, nothing, or just a little stain. So, if there is a deep groove, but no decay and only a little stain, do you go ahead and fill it? In cases like these, we observe, or watch these areas to see what happens over time.
Most of the time, nothing happens. Occasionally, these areas begin to decay, then a filling or other treatment is needed. If we filled every strange looking area, we might end up filling a tooth that might not ever need any treatment. It's a judgment call. Even then, not everything is in our control. Good brushing and flossing, adequate fluoride and a good diet can take a little "watch" area and keep it from ever turning into a cavity. Other times, we try everything under the sun and the area still decays--sometimes rapidly. By the way, an in-between the tooth cavity on a baby tooth can rapidly get close tot he pulp--necessitating a pulpotomy or more extensive treatment than just a filling.
Hi. I was horrified last night to realize that my 7 year old looks to have a cavity on her bottom 6 year molar. When we were at the dentist (a little over 6 months ago) I had them apply sealants to her bottom 6 year molars. The last few days she has been eating blueberries, and the skin was getting stuck in what appeared to be a groove in her back molar. However, last night, brushing would not remove it. We had to actually use a pick to get the blueberry skin out. When we did this, it appeared to be a cavaity that it was actually becoming stuck in. (My husband's father was a dentist/oral sergeon, so my husband is pretty well versed in what cavaties look like.
I was (and am) very upset given that our daughter does practice good dental hygene (or se we thought), doesn't eat alot of candy, doesn't drink pop, etc. Plus, I was under the impression that the sealant would almost eliminate the possibility of cavaties...especially on the top where it was applied. I am calling the dentist on Monday, but what should my questions be to get a good answer as to why she got a cavity even with the sealants?
I was incredibly upset last night in finding what appears to be a cavity on one of my 7 year old's back molars. When she was at the dentist last (approx 8 months ago) we had her bottom molars sealed, as they had come in and we were able to do so. However, after two nights of trying to get what appeared to be blueberry skin off the top part of her back tooth, we now believe that she actually has a cavity.
I am very upset and a bit mad at myself. She claims that it doesn't hurt, and so now I am wondering if it is indeed a cavity or could is possibly be a crack or a chunk out of her sealant? I am calling the dentist on Monday morning to get her in. However, is it possible to get cavities on the tops of teeth which have been sealed? Thank you!
First, it might not be a "cavity". It might just be where the sealant came off, had a small void exposed. It could just be the original deep groove with blueberry and all stuck in there or just stain that can't be brushed out. Ok, if it is a true cavity, then that is easily remedied with a small white filling (which is pretty much the same material as the sealant. There is a continuum from sealant, to deep sealant, very shallow filling, and filling. If the child is not prone to caries (cavities) then not as likely to be a true cavity. Just let the dentist take a look and see. Good luck.
Hello. I'm 38 and whilst being fitted up for a temp bridge off a canine whilst waiting for an inplant the prosthodontics drew on the back of the canine where my bite wa. He scored very fine lines in the enamel on the back of the tooth and created a deeper groove in the filling part. It's not caused any exposure to anything but im paranoid now it will get infected. Should I ask him to place a sealant in the tiny groove he made in the filling? I don't want him to redo the filling as the filling itself was fine until he drew a line in it. Thanks
I have thought the procedure of sealant is very simple and it takes short time. But in fact, it took two times to do the sealant for my 9 years old son. And each time the dentist gave him shots of anesthetic. The description of the first Statement of Services Rendered just says sealant. The second says POCM2-2s, posterior composite. So is it the necessary procedure of sealant for my son? Thank you!
Speculation: Sometimes, you start the plan as a sealant. As you clean out the grooves, decay may become more evident. This necessitates a restoration ( it is really a sliding scale between what is a sealant and a small filling.) Numbing is done when you think there is, or will likely be sensitivity.
Hi My Daughter is nearly 8 years old, she has her bottom back adult molars, last night whilst brushing her teeth i noticed a pinpoint brown depression on her adult molar, is this a cause for concern?
A "Pin Point" brown spot is likely just that, an insignificant stain or spot, not a cavity. However, that's why you get the pediatric dentist to examine it and use his or her judgment if it is a concern or not.
Hi was wondering why my 6 year olds dentist wants to put sealant on her molars but they haven't broken through yet. you can see the molars coming but there's a layer of thin skin over them. My friend thinks this is a waste of money and to wait until they break through all the way is sealant pointless right now?
I usually wait till the 6-year permanent molars come in enough so I can properly place the sealant material. It is not unheard of to try and seal them as soon as possible to get some protection, but teeth like that often have to be resealed once they are all the way erupted.
I was recently told my 8 year old's molar has a tiny hole on the side created during the development of the tooth, it does not have any decay and is not a true cavity with bacteria but the dentist is recommending drilling to make the hole bigger to then place a filling. He stated he would also need to cut away a small part of the gum to do this. Could sealant be used instead where the tiny hole wouldn't be made bigger and the gum wouldn't have to be cut. Also, my son has never experienced any pain there and has never had a cavity. Thanks
I see these pits all the time. Sometimes they are concerning enough to do as has been described. Sealant and filling material is pretty much the same thing. If the pit is deep/big enough, a small bit of cleaning and preparation of the area for a tiny filling is best in the long term as a sealant might not last. Each case is different.
I have to get a sealant and I am wondering if it involves shooting Novocain into your teeth and if it hurts
No numbing needed for just sealants.
I have a three year old daughter who has deep grooves on all eight molars. In addition she already has a cavity between E and F. To further complicate matters, I do not have even equal custody and do not know what kind of oral hygiene her mother provides. I would like my daughter to get sealants, but her pedodontist does not recommend them.
I have searched, with little success, on reasons why sealants are not recommended for baby teeth. Other than the reasons you wrote about, are there any other reasons sealants are not recommended for baby teeth? Are there any absolute contraindications to sealants on baby teeth?
I spoken with the office manager of my daughter's dental clinic. She says they, the dental office, do not recommend them since the baby teeth will fall out anyway (?!?!) and would rather just monitor the molars until sealants are needed.
The reasons I listed are the main reasons sealants are not routinely done on baby teeth. However, they can be done and are sometimes done without problems. The main reasons you might think twice are 1. Behavior (can the child easily sit still and receive the treatment (though it's rather easy) 2. Are there signs of decay or questionable areas that might become decay in between the teeth in the back (the sealants only protect the top of the tooth.) Otherwise, it's fine to attempt sealants on baby teeth.
"..do not recommend them since the baby teeth will fall out anyway (?!?!) " -- is a terrible reason imop.
