Cost of braces or Invisalign to fix your overbite will vary depending on the treatment modality you choose and the provider you choose. I would highly recommend choosing an orthodontist, since they are specialists in correcting teeth position and bites.
The price is very variable. In our practice, it should be somewhere between $4,000-$5,000, depending on a complete examination of your case and the treatment you prefer. It should take between 1.5-2 yrs.
Hope it helps!
