A REALLY Weird thing happened last dentist visit I had. It has been bugging me ever since and I havn't gone back. I went in thinking I might have a cavity or two, turned out it was just my teeth being sensitive again. But as he checked me out, each time he touched my gum line with the instument my gum actually popped open, receeded before his eyes. He didn't say anything, he jumped back like he was in shock and I felt it happen! It happened three times in different areas of my mouth. Each time I could see he was freaked out. After the third time, he ripped off his mask pushed himsefl away and left not saying a word. He never came back. A good ten mins later, I flagged down an assistent and asked if he was coming back. She came back and said No. I asked if I had any cavities or what? She went to ask him and came back, she said no cavities but I have receeding gums on the inside and need to have them built up for 795. I don't get how I go in with no problems and go out with receeding gums and need to spend 795. to fix it. Have you ever heard of this happening before?
