Minnie,

Get thee to a dentist. Especially after radiation oral health is paramount. I have my teeth cleaned every 3 months. Bleeding from the gums is not normal and might be able to be taken care of with a good teeth cleaning and maintainence. (I used to sell dental products and still had 14 teeth pulled for radiation) I now practice what I preach.

I'd have it checked out and get on a regular schedule.

Take care,
Dinah
