I don't have any extra bones, but I do have a gap where food gets stuck and it would sometimes cause gum irritation.

My dentist never told me about WaterPik, but I bought one anyway. I use it twice a day and never have gum problems now.

Why don't dentists recommend this for everyone?

(My wife won't use it; she insists that riinsing is enough and less messy. I agree with the messy, but I gthink it works much better than any amount of rinsing)
