What is underbite?
Underbite is a misalignment of the teeth which occurs rather rarely. As opposed to overbite, in cases of underbite the lower row of teeth protrudes beyond the upper row. In other words: The lower jaw protrudes too far in relation to the upper jaw.
Underbite - possible consequences
Apart from aesthetic criteria, underbite can impair normal front tooth function and cause wear and tear to the teeth. Difficulty talking, chewing problems, your lower lip jutting forward and chronic throat inflammation can also be the result of underbite.
