Can buck teeth occur only in the lower jaw?

Buck teeth, also known as protruded front teeth or overjet, generally refer to a specific dental condition where the upper front teeth extend significantly beyond the lower front teeth. This condition is more commonly associated with the upper jaw (maxilla) and is a result of various factors, including tooth alignment, jaw positioning, and sometimes habits such as thumb-sucking.

In terms of dental anatomy, the term "buck teeth" is not typically used to describe a condition that occurs exclusively in the lower jaw (mandible). Instead, if there is a dental issue with the lower teeth protruding, it is usually classified differently, such as underbite or dental crowding.

Therefore, the correct response is that buck teeth cannot occur solely in the lower jaw, as they are characterized by the projection of the upper teeth relative to the lower teeth. Understanding this distinction helps clarify the definitions and classifications of various dental conditions.
