Q.
Dear Dr Gambroudes.
Sometime in February last year, I had a weird sensation on my left canine tooth. I felt this sensation even more strongly whenever I had something to eat or something to drink. As soon as I could feel it, I’d have to stop eating or drinking because it got too intense. This went on for a couple of weeks. A few weeks after I first felt it, there was a chip on the tooth, which then left a hole in the tooth. A few days after that, I noticed that the affected tooth was changing colour. What could be the problem, and what do you advise I do in these circumstances? Thank you.
