If you are about to have a dental procedure (Teeth extraction, root canal) make sure you tell your dentist you are taking those drugs as they may cause osteonecrosis of the jaw as a result of such procedure, a nasty thing....
I had to go thru such procedure and my dentist wont let it go until I told him exactly which drugs I take for PC treatment.
My guess is that not every dentist is aware of such contraindication
