It sounds like your doing a good job of taking care of your teeth. I used a regular tooth brush on my teeth, mostly because elective boothbrush were not around that much, like they are today. My gums did bleed some, but wasn't that bad. I was told to make sure that I brushed and flossed my teeth. I would let your dentist and doctor know what is going on and see what they recommend. I hope this helps you.
Had My Brain surgery, and I was so scared, but the doctors made me feel good and and I did. They kidded with me before the surgery and before I knew it I was in recovery Thanks for helping me. Mine is on the left temporal lobe. They say it is deep it my brain.
