The typical mouth of an ordinary individual will have developed 20 teeth as a child and 32 adult permanent teeth when full-grown. That is, if they do not have a rare condition known as hyperdontia. A person with hyperdontia will have more than the normal amount of teeth. The extra teeth are called supernumerary teeth and they can be located anywhere in the gums, palate, or in any dental organ.

Although rare, over 200,000 Americans have the ailment. More males show a propensity for the condition and display supernumerary teeth at twice the rate of females. Some people have reported over 30 extra teeth, although the majority of sufferers are limited to a single extra tooth conveniently uniform with the rest of their teeth. Persons with extra teeth will most-likely have alignment issues, especially if they have more than one, and should be checked by a dental professional. Common treatment is simply to remove the extra teeth.

There is little understanding about what causes hyperdontia, and how to effectively combat its appearance before the teeth begin to grow. The theories about what precipitates it are not universally agreed upon, and consensus is only that it has a genetic factor.
