I had braces before to correct my overbite and other biting problems at the back. Two upper teeth were removed during this process. After the braces are taken off, my dentist told me to go to other orthodontists to see what they could do about my bottom two second molars because they are not entirely out. My dentist suggested a jaw expansion. However, from what I've noticed, I might be a class II profile; my lower first molars bite on my upper second molars. By expanding my jaw and bringing out my lower second molars, will class II profile be fixed? Since two upper teeth were removed to fix overbite, will there be enough space in the upper jaw to bing the lower jaw forward? Are there any other ways to fix this?
