underbite

This term is primarily used in clinical dentistry and orthodontics to describe a specific skeletal or dental misalignment. It carries a neutral, descriptive tone in medical contexts, though in social contexts, it may be used to describe a distinctive facial feature.

Because it refers to a specific anatomical condition, it is typically used with verbs like "have," "correct," or "treat." It is distinct from an "overbite," which is the opposite condition where the upper teeth project further than the lower teeth.
