Hi, I went to the dentist last week for my annual check-up. I have never had any trouble with my teeth (no fillings etc.). My gums have been a little sore since which is to be expected as she gave them a thorough clean. However, I am getting a pain at a particular point on my gums. It is at the back of my mouth next to my back wisdom tooth. The tip of the gum has gone a little black in the past couple of days and when pushed a little, I can separate the gum from my tooth. Having looked at google, it could be Pericoronitis? I have a feeling she may have 'drilled' into the gum accidently when cleaning and caused some trauma? Any views welcome.
