Underbite is a malocclusion; it corresponds to the fact that the lower teeth, when the jaw is closed, extend out and cover the upper teeth.
In a “normal occlusion”, it is the reverse: the upper teeth extend out and cover the lower ones.
Underbite is mainly found in patients whose chin is too far forward. In medical terms, this is called prognathism, and it can be fixed with surgery, which enables good occlusion to be recovered.
Underbite localised to one or several teeth is often associated with postural issues (such as neck and back pain).
