I have a hole on my upper gum that leads to my nasal cavity. The hole is due to having a cleft lip and palate as a baby and the hole is right above a canine tooth. My orthodontist said that their is a high possibility in loosin my canine tooth by doing a bone graphing to cover the hole thats right above it. The hole is not big but im not too happy about them having to take a piece of bone from my hip and possibly loosing my canine tooth. Do I really have to have a bone graph? If so, how painful would it be to recover from and how long would I have.to recover before going back to work amd school.
