I used Crest 3 D white strips almost 6 weeks ago. First I got a rash on right cheek and gums, and my top left gums where white. I went to the my Doc, who sent me to an ENT. I went to see him 2 or 3 days later, and by then my gums where covered with oval blister type bumps, covered with tiny white balls.Plus I had a couple other types of sores throughout my mouth... He said he had never seen anything like it... Daily my mouth looked different.. My little triangles of gum between my teeth, 6 of the top front ones fell out... Almost a week ago, I wenyt to bed with no gums, and the following morning all 6 had grown back enough to fill 1/2 to 3/4th of each gap. My canines are the worse problem, with crystals growing around them and the gums next to 2 of them have been completely replaces by these round ball crystals. I had roots of 3 teeth totally showing, and the 3rd tooth showed nothing but shelves of bone... A lot of the gum is growing back. I see a periodontist in a week and I hope to find out nothing too bad, though I ve been warned of bone and possible gum graphs... Have u ever heard of anything like this, and have u heard of Oramd (toothpaste drops) helping????
