Need underbite correction?

Transform your underbite with SmileDirectClub.

What is an underbite?

An underbite is a common misalignment where your lower teeth extend out past your upper teeth when your mouth is closed. It can be hereditary, and may be caused by your lower jaw coming further forward than it should.


Orthodontists refer to an underbite as a class III malocclusion or prognathism.


An underbite can make it difficult for you to chew properly - and lead to speech issues, headaches, teeth grinding, and even sleep apnea. So, definitely worth correcting.
