My orthodontist claims that my overbite could never be corrected due to the thickness of my teeth? Is this true? (Photo)

If your teeth are large and you are bothered by large width as well which creates a significant overjet and overbite space with the lower teeth, one option would be for your dentist to perform a minor amount of interproximal reduction or IPR.This procedure would recontour/file a small amount of tooth enamel (often less than .5mm), most commonly, between the upper anterior teeth, to create the space and allow movement necessary to correct most overjet/overbite concerns. IPR is commonly done with Invisalign clear aligned therapy to facilitate movement of teeth. You should always consider a second opinion for any issue you encounter before during or after treatment.

Have you considered seeing a surgeon. Your jaw might be too small to handle just orthodontic treatment.
