I saw a dental hygienist yesterday. I hadn't been for about a year and she did a lot of scrapping around. At the polishing stage, she missed my teeth and hit the floor of my mouth and caused a hole. For the whole yesterday afternoon the area under my tongue was badly swollen up and it hurt to open my mouth and to eat. Had to take pain killers to eat supper. Today, the whole area under my tongue looks like there's been significant bleeding under the surface (it's basically black!) and is still a bit swollen. That's not usual, right? Not sure I"m every going to the hygienist again if it is......
