First I must say that I have never heard of anything like that ever. I seriously doubt there would be more to come. Xrays would show however if there were. You can see them on Xrays of children. The adult teeth are visible under the baby teeth.

You’ve already had one more set than most adults; so, I don’t think I’d push it!!! As @anniereborn said, your dentist should be able to tell you. I’m guessing NOT because your dentist should have already been able to see them while doing the x-rays for your previous work!!!

If you had teeth not erupted they are visible on x-ray. Don’t mess with what you have. Save them. Never pull a tooth needlessly!

Amen @si3tech!!!

This is a question you ask your dentist, not me.

If you are going to get another set of teeth they will push out your existing teeth anyway. It makes no sense to remove your teeth and crowns.

If you have seed teeth growing behind your current teeth they would show up on an xray. The first thing a dentist does is take an xray or your teeth to reveal any cavities or current fillings or work you’ve had done. The dentist can tell you, definitively, if you do have other teeth coming in. I have heard of the odd ‘extra’ adult tooth in American Indigenous populations, but never, ever, a full set. With children, adult teeth are developed in the skull and await eruption to push the baby teeth out and they are visible on xrays from about 3 years of age. As these adult teeth are growing in the skull of the children, it is when fluoride and good nutrition is most important for the creation of these teeth. Here is an example of what the teeth look like forming in the skull of a child: https://neeshdental.wordpress.com/2016/03/03/childrens-skulls-complete-with-teeth/

If you had teeth behind the adult teeth you currently have, they would show up on an xray, looking similar to the teeth of a 5–8 year old. Chances are, you do not have any of these extra teeth though, so don’t go pulling any of your teeth on your own, thinking your body is somehow going to grow new ones out of the need. Your skeleton doesn’t work that way.

@ScienceChick – is right: you are not a shark. You only have so many teeth in your jaw.

NBC News also reported it, but the story only shows up in the headline. https://www.nbcnews.com/healthmain/boy-extra-set-teeth-1C9926253
