We can get 3 sets of teeth?

I came across a local newspaper article from 1922 in which it told of a resident who was cutting his third set of teeth. He was 92 years old and the new teeth were through the gum and getting larger. How common is this?


Dentist here. Never heard of it. More likely was a previous unerupted tooth cutting through. Had a patient with a denture for over 30 years. the wisdom tooth wasn’t extracted since it wasn’t erupted, for some reason after over 30 years it erupted and had to be extracted.

According to Wiki:

It is possible to have extra, or “supernumerary,” teeth. This phenomenon is called hyperdontia and is often erroneously referred to as “a third set of teeth.” These teeth may erupt into the mouth or remain impacted in the bone. Hyperdontia is often associated with syndromes such as cleft lip and palate, trichorhinophalangeal syndrome, cleidocranial dysplasia, and Gardner’s syndrome.

true, the most I personally have seen on one of my patients is a full set of fourth molars behind the wisdom teeth along with two mandibular fifth molars. A supernumary between the upper central incisors is quit common. One extra wisdom tooth (fourth molar) is also common, see them several times a year. Pathology books often have good pictures of odontomas causing multiple teeth. None of these is my opinion is a third set of teeth and while I haven’t seen the 1922 article I don’t think a third set of teeth replacing the permanent set the way it replaced the primary teeth happens.

I had a third “front” tooth that came in behind the two normal front teeth, kind of the roof of my mouth. I think I was about 10 when it starting showing, dentist removed it.

He told me that sometimes the tooth “buds” can have pieces break off during development that then become an extra tooth.

When I was a kid, I used to see people all the time who had what looked like an extra tooth high up in the canine region, and rarely see this any more. Is that what it is?

(Conversely, I had two lower premolars whose permanent teeth never formed. They were pulled and the surrounding permanent teeth brought together.

Here’s a journal article about a young man who had a rudimentary extra set of wisdom teeth. Warning for the squeamish: It does include color photographs of the extraction.

The lil’wrekker is 19 and still has 2 baby teeth. Front lower bicuspids ( I think what you call them). There are no adult teeth in there. The dentist said if she ever loses them she will have to get implants. For the moment they are healthy. Teeths is strange!

My brother has enormous restraint and self control. Because of this, he has 7 gold teeth that came in as permanent teeth, because he was able restrain himself from sticking his tongue in the gum area where the baby teeth fell out.

I had a baby tooth until I was 56 when it finally broke. They can last a long time. Lower second premolar. Fairly common to have that one missing. Don’t think a week goes by that I don’t see one.

My eldest son had his adult canines erupt above his baby ones, rather than pushing the baby teeth out. The dentist pulled the baby teeth and the adult teeth shifted into their proper place unaided.

If the people you saw didn’t have a dentist pull their baby teeth, the adult canines would have just hung out in the gums above them.

Glad to hear that. She’ll be old enough to get her own implants.

WTH? Am I reading this right? Gold?

Never heard that story as a kid?

He also had hairless palms as a teenager, owing to that same self-restraint.

I hadn’t, but I did find it on the Internet, so it wasn’t just a local family thing for you (unless this woman is related to you somehow . . .)

No, I was told that if you pick a guinea pig up by its tail its eyes will fall out.

Oh, that’s true about guinea pigs.

Don’t Coneheads have three sets of teeth? Simultaneously? Beldar did.

Can’t speak for humans (or Coneheads), but one of our cats had two sets of adult teeth.
