What happens if i have a class 1 overbite and a class 1 overjet do i need braces?

Maybe: Spacing? Crowding? Rotated teeth? Your post did not say. A local orthodontist is better prepared to answer your question. Make the appointment.

Class I: Class I describes front-to-back dental and skeletal relationships, not overbite/overjet. Do you need braces? See an Orthodontic Specialist for initial evaluation (usually free or modest cost). Malocclusions are like snowflakes, no two are exactly alike. Ask a pro to take a look and advise you. It will be time well spent.

Discuss: with your orthodontist who is in the best position to tell you.
