The most prevalent odontogenic tumors are odontomas and and are generally regarded as hamartomas rather than true neoplasms. They are composed of various dental tissues. Odontomas are typically asymptomatic, slow-growing, and are often associated with unerupted or impacted teeth. In many cases, they are discovered incidentally during routine radiographic examinations, although they may cause bony expansion.

Odontomas are classified into two types: compound and complex. Compound odontomas are composed of multiple small, well-organized, tooth-like structures. In contrast, complex odontomas consist of a disorganized conglomerate of dental tissues that bear no anatomical resemblance to a tooth.
