Hi, I ve recently started flossing after my dentist insisted. It seems to be going well except for between two teeth: my right upper canine and the adjacent incisor. When I push the floss down between them, there is a sharp stabbing pain. I ve had a look around on the internet, but everything I see seems to have to do with gums. This is not my gum - it is at the contact point between the two teeth (my teeth are slightly angled towards the front of my mouth). I saw the dentist last week and he didn t see anything, but I m worried it might be something he couldn t see.
