yesterday, while flossing,a chunk fell out and now I have a crack in the back of one of my front teeth. I know I have been stupid in the past to avoid the dentist for so long but Im really scared. I have booked an appointment for Friday, but I am really stressing before that time.  How can I tell if I have lost part of my tooth, or if it is hardened plaque that has come off?
Hello, thank you for consulting with Chat Doctor. I think there is nothing to worry as the tooth structure is the hardest substance in your body which will not just chip out with a floss, it must be the calculus (hard plaque). Yes but in a case when your tooth is infected from a long time in that it becomes brittle in that case it can chip off. But don't worry, visit the dentist to make it fine. Hope it will help you.
