I had braces when I was 13 years old for a year. After that I was given retainers to wear at night. But about 1.5 yrs back, I visited another dentist who said I can stop wearing retainers. But since I stopped, my upper jaw teeth are protruding again and the dentist said I have overbite and it cannot be corrected at my age as its too late. So now again I'm wearing retainers at night so that it doesnt worsen. Is there any treatment for overbite at my age? I have gaps between my teeth which looks bad, so is there anything we can do about that?
