hi a couple of years ago my wisdom tooth (top right) fell out which has left a shallow hole in the gum where the tooth was. a small amount of the tooth remains on one side that sticks up above the gum about 1mm. my dentist (NHS) encouraged me to get the tooth removed because he said the nerve is exposed and i could get an absys however i haven't wanted to because i've never had any pain but mainly because i'm scared! until recently i could get food out of the hole with my toothbrush but the last few weeks i haven't been able to and now i'm sometimes getting a taste in my mouth that i think maybe rotting food stuck in the hole. what should i do please?
