While some people have smaller teeth than the average person, some have larger teeth than others. This may include teeth that are wider or longer than average, and it is referred to as macrodontia and is typically the result of genetics. In addition, macrodontia can result from specific syndromes, hormones, and glandular imbalances. Macrodontia comes in three forms, isolated macrodontia, true generalized macrodontia, and relative generalized macrodontia. Isolated macrodontia is when only one tooth is affected, which is quite rare. True generalized macrodontia is extremely rare and is when all the teeth are larger than they should be. Finally, relative generalized macrodontia is when the teeth are large for the individual's facial structure whose teeth are actually of average size.
