Congenitally Missing Permanent Teeth
Take a look at this Panoramic Radiograph. If you know what to look for, you will see several missing permanent teeth. They never formed. This is more common that you may realize. It tends to run in families too, but not always. If there is no permanent tooth there, then the baby tooth will likely remain. Premolars and lateral incisors seem to be the most common (and third molars too). Usually it's just one or two teeth that are missing. This x-ray shows Seven missing premolars! (bicuspids). I've seen more than that on some kids.
Treatment can vary and can be anything from doing nothing to orthodontic treatment to close spaces, to a bridge or implant placement at an older age. The main thing is to know it is managable. In fact here is a patient who had two lateral incisors missing (that's the two teeth on either side of the two middle ones). Orthodontic treatment closed the spaces. Can you tell there are two missing teeth?

My son is missing a lateral incisor. He's 6 years old and his baby tooth just never came in. Does that mean he likely won't have an adult tooth there either? He's only missing the one, his other is normal looking. I can't recall what it's called, but both of my lateral incisors were stunted looking, like little fangs kind of. I had them capped when I was 13 (am 30 now) and my dentist says they are still fine. (He expected to have to fix them again when I was around 18/20 approximately) Are there any other worries that would come from him never having a baby tooth erupt there? Thanks, your site is very interesting!
Small lateral incisors are called "peg" laterals. Missing baby teeth do not necessarily mean missing permanent teeth. Have your dentist get an x-ray. They usually can tell with that. Missing teeth tend to run in families.
My 1 year old has all her teeth, but the two that are by the 2 front teeth. Sorry, not sure what they are called. The pediatric dentist my other daughter goes to said he can't feel any buds. When do I start to worry ? What age do I need to take her to an orthodontist? thanks !
I would suggest you go see a pediatric dentist to evaluate if there are any special considerations. One year olds tend to get teeth in odd sequences sometimes.
My grandson is 10 months old. His maxillary right central has erupted. In the space where the left should be is what I think is called a bifurcated central. The crown has a sharp point on the distal, then a rounded side on the mesial. If I am right how should we follow up? Wait or go to a pedodontist soon? What can be done. Grandma is a hygienist.
The AAPD recommends going to the pediatric dentist by one year of age. It's ok to go sooner if you have a concern! Most of the time if there is a partially geminated or fused tooth, you don't "do" anything right away. You might want to look at the post titled gemination and fusion of teeth. Could be something else too.
How is missing teeth passed on in a family? My husband misses 2 lateral incisors. But no one else in his family has this condition. My son is 2 years old now. Yet the 2 lateral incisors are not formed. What are the chances of him never having the 2 teeth? Thanks.
My daughter (nearly 7) had her first xrays today and we found out she is missing 9 permenant teeth. How reliable are these first xrays? I have seen postings online where people mention that teeth were 'hidden' or not yet developed and later xrays show fewer teeth missing. Curious what the chances of that are.
Well, at 7 you can see a lot of teeth especially the front ones. You can usually make out the bicuspids, but sometimes I have seen them form late. You can be hopeful, but don't get your hopes up. By the time it is really important to know (braces etc.), the radiographs will show whether they have formed or not.
I had a aunt who was missing all perment teeth. My mother missing some. I have two upper laterals missing. I am 38. my perment cuspids moved forward and my baby cuspids where bonded to look bigger. My 5 year old is missing a baby lateral. Her pan-xray shows her missing her laterals also. I had a pan-xray on my 10 year old who is also missing a secound bi on the lower. I have one more child left to see if he will have the lucky gene to. He's 3. I have been a dental asst. for 20 years now. I have heard meny people refuse a pan xray.That xray tells more stories then you think.
My 13 year old daughter is missing all bicuspids (8 teeth). In addition, her lateral incisors are extremely small. We have seen several orthodontists who have given us somewhat different advice. My question is does she need braces to close the gaps and eventually implants? I want to have the small teeth bonded, but I'm not sure if I should do this yet. What do you suggest?
every orthodontic case is different and dependent on measurements,growth, etc. It is not unusual to bond small laterals or to close spaces or do implants if there is simply no way to close spaces. I cannot tell you which is the best way.
I am missing my top right lateral incisor, and I am soon getting orthodontic braces to close the gap by moving the upper canine tooth into the space normally occupied by the lateral incisor. Do you have any information and/or photos of people who have had only one missing lateral incisor and had the gap orthodonically closed? Any would be greatly appreciated.
A common treatment is to close the space. The photo above shows two missing laterals, so look at that and one side would be like that.
Sorry I'm an adult please help if you can...I'll make this quick I hope. I was born missing my upper and lower lateral incisors. In 2001 I got braces to have the space created for the teeth. Well it's 2008 and i'm still wearing my retainers b/c I am not able to afford ANY of the post treatment. Question: Am I able to have my orthodontic treatment reversed? Meaning am I able to get braces again to just close all the space and be done with this. Please, any answers...Thanks in advance for you help.
Basically, yes. Braces can be done more than once.
In a case where a child is missing the adult K9 teeth bilaterally, is pulling the other teeth forward, as in the picture above, a better choice than implants?
No way to say as each case is different. Analysis and consultation with your pediatric dentist or orthodontist will yield a reasoned answer for an individual case.
