Is it normal to have 3 sets of teeth?
Up to 3.8% of people have one or more extra (supernumerary) teeth. An extra tooth can be visible (erupted) or impacted (not broken through the gum). You may not notice hyperdontia in children. Extra baby teeth tend to look normal, come in regularly, and be aligned with the rest of the teeth.
Do humans have 4 sets of teeth?
These teeth are eventually replaced with 32 permanent adult teeth, 16 on each upper and lower jaw, as we grow older and our jaws start to develop. We have four different types of teeth, with each type serving a particular purpose for eating and chewing.

4 Types of Teeth and Their Functions
- Incisors. The incisors are the types of teeth that greet your friends, family and grace your photographs.

- Molars. Your molars are next to your premolars.
How many sets of teeth are you supposed to have?
You get two full sets of teeth over your lifetime. As a baby, you have 20 teeth, and as an adult you should have 32 teeth. Among the 32 teeth, each has its own function in the chewing and eating process.
Can you have more than 2 sets of teeth?
Those teeth are small developing follicles which grow and erupt through the surface when they are formed. While there have been rare cases of hyperdontia, where an individual is born with extra or super-numerary teeth, for most of us two sets of teeth are the maximum we will ever achieve.
How long do teeth last on average?
If cared for properly, your teeth can last a lifetime. Your mouth changes as you age. The nerves in your teeth can become smaller, making your teeth less sensitive to cavities or other problems. If you don’t get regular dental exams, this in turn can lead to these problems not being diagnosed until it is too late.

Why do we only get 1 set of teeth?
So the leading theory is that adult humans can’t regrow our teeth because it was better for survival to only grow one, well-aligned adult set. However, if you still wish you could regrow a tooth, there may be a way in the future.
Is it rare to have 32 teeth?
A very few people have more than 32 teeth but this is considered an anomaly. In general, probably over decades of evolutionary time, our jaws have gotten smaller so that there is not enough room for the full compliment of 32 teeth.
Why don’t we get a third set of teeth?
It sounds good in principle, but with each new set, there’s a risk that the regrown teeth won’t line up. So the leading theory is that adult humans can’t regrow our teeth because it was better for survival to only grow one, well-aligned adult set.
