I'm 16 and I have an impacted incisor tooth. My dentist have been trying to pull it down with a traction chain for two years already but it keeps falling off. No improvement. It's still lying under my gums. I don't know why. When I speak, it just falls off. It doesn't even last a minute to hold onto my gums because right after the dentist have attached it, it falls off. Why is it so? I need my teeth to improve because I'm already going to college. Please I need your help.
