There are two types of microdontia, true generalized microdontia and localized microdontia. True generalized microdontia is when you have a complete set of atypically small teeth, and it is rare. However, localized microdontia is when one tooth is smaller than the rest of the teeth, which is much more common. While microdontia may seem insignificant outside of aesthetics, it can cause more serious issues. For instance, it can lead to unnecessary wear and tear because microdontia can create an improper bite, creating weakness of the tooth structure and even tooth decay.
