Is it possible braces to fix my teeth for about 9 months or 1 year to correct my bite? Because my Dr. said that i only have to wear them around 9 months or a year. I have 4 tooths been extracted which are 2 premolars (upper) and 2 second molars (lower). So, I have four medium gaps and an overbite. How long do you think I need to wear braces?
