What is the dental term for two teeth developing from one main crown?

The term for two teeth developing from one main crown is gemination. This occurs when a single tooth bud partially divides, resulting in a tooth that appears to be larger than normal and has a shared pulp canal. Gemination typically leads to the formation of two crowns on a single root structure, thus creating the appearance of two distinct teeth, often connected at the top.

In contrast, fusion involves the complete union of two separate tooth buds, which creates one single larger tooth with two roots or crowns. Dentinogenesis refers to the process of dentin formation in developing teeth and does not pertain to the morphological alterations of teeth, while condensation is not typically used in dental terminology to describe tooth development. Understanding these definitions clarifies the unique characteristics and implications of gemination compared to other dental conditions.
