Do you know how many teeth adults have? 32. What about baby teeth? If you said 20, boom, you won again. And for our final round, what is the name of the condition when you have too many teeth? That is called hyperdontia. We would've also accepted supernumerary teeth. While we aren't handing out any trivia points, we can point out all of the ins and outs of hyperdontia — and that wealth of dental health knowledge is a prize in itself.
What Is Hyperdontia?

We've established 32 is the magic number for adults. And the majority of hyperdontia cases aren't severe with just 1-2 extra teeth popping up. The causes of these extra teeth are still unknown, but many cases link to specific genetic factors. A large number of people diagnosed with hyperdontia also live with one of these genetic conditions:
- Ehlers-Danlos syndrome
- Gardner's syndrome
- Down syndrome
- Cleft lip or palate children
Sometimes, you may have hyperdontia that will require little to no dental attention. And chances are, you won't know you have it until after a dental exam or X-ray. The extra teeth could cause pain, discomfort, and affect your chewing and eventually lead to other oral health concerns, such as:
- Crowded and displaced teeth leading to the blockage of your primary teeth from coming in properly
- Pressure can build in your teeth when a tooth doesn't come in straight, leading to impactions
- Cysts and tumors can form from hyperdontia
- Supernumerary teeth can create malocclusions or issues with your bite, alignment, and jaw position
- The more teeth, the better chance for tooth and gum infection, decay, and periodontal disease
- Facial deformities and speech impediments are possible in the most severe cases
There are a few courses of action when looking into hyperdontia treatment. Each treatment depends on your age and the number of overgrown teeth. Be sure to speak with your dental or orthodontic professional to go over your options. Possible treatments include:
It's impossible to control if and how hyperdontia affects you. What you can do is regularly brush, floss, and see your dental professional so they can assess your oral health and recommend any treatments as necessary. If you do that and keep your teeth, mouth, and smile in tip-top shape — you'll be a winner.
