A very good friend of mine was in a mini bike accident... well let s just say a bunch of the guys (we are all over 50) decided to get minibikes and have races... the one in ? Went ass over end and landed on his head (yes, he had a helmet, but it cracked fown the middle).. he wears dentures, but hears a clicking, and had a bloody nose, which I told him could be from the palate being cracked.. doesn t that protect the mouth from the sinus cavity? Anyway, will it heal on its own, or should he see an oral surgeon? Thank you!!
