I went to the hygienist on Friday, when I was there I felt her dig her descaling machine (sorry don't know the correct name for it!) in between my teeth (it hurt!). When I got home I have discovered that she has made a hole in the gum between the top of my teeth (I think it's called the interdental papilla?). I've uploaded a photo (not very flattering!). I'm really upset as I can see the hole when I smile & am annoyed that this damage has been caused :-(. Please can anyone tell me if the gum is likely to regrow & cover the hole? It feels weird & slightly painful at the moment and I'm worried that food & stuff is now going to keep getting stuck in it & could cause me problems?! Please give me some advice?
