I had 5 extractions. in the bottom of my mouth. i just got the bottom denture.. My problem is that a small piece of the bone is sticking out. my dentist told me it would heal itself. it hasn't ..I have tried to wear my denture as suggested by my dentisty. it is very, very painful as the denture is rubbing against it. i am going away in six days.How long is the healing time if he shaves down the bone & how long before i can wear my bottom denture?
