Diastema is a term used in dentistry to describe a gap or space between teeth, typically located between the two front teeth. There are several synonyms for diastema, including tooth gap, incisor gap, and midline gap. Other synonyms for diastema may depend on the specific location of the gap; for example, a gap between molars may be referred to as a molar gap. Additionally, some people may use more colloquial terms, such as "buck teeth" or "rabbit teeth" to describe a diastema. While diastema is not typically a medical concern, it can cause self-consciousness or difficulty biting or chewing for some individuals.
