I used to have bleeding gums, but flossing makes a big difference. A dental specialist years ago told me to floss with baby yarn in the gaps that are wide enough. My teeth have never been anywhere near perfect and I give them less attention now than I would like. But for some reason they are holding up well. Just another of those things that doesn't make any sense in our lives. My best friend is a dental hygienist and she gave me one of those super deluxe rechargeable toothbrushes and it cleans my teeth really well. I also get canker sores from too much orange juice. Try a supplement of ester C. I take 3000 mg daily. (spread out through the day). No cankers. Also calcium and magnesium for the underlying bone structure, and there is a herb called Goldenseal that destroys the bacteria that causes peiodontal disease.... Carry on and let us know if any of this free advice helps.
