Hello all, when I went to my dentist for my regular check-up I mentions bleeding gums when I floss, I used a sensitive toothpaste, but he suggested the oral B one mentioned, mine was blue gel that I was given as a sample, (Pro expert anti bac/flouride)I can't find that one in the shops but the one I do have is a sort of white with blue "gravel" in it... (Pro expert flouride) and I too find it makes the skin in my mouth come away in long strings... It's horrible, have just in the last few days gone back to my normal Colgate pro relief, sensitive one, because my gums still bleed when I floss even with the stuff he gave me. Apparently it's a meno/hormone thing that will probably sort itself out in time.
