About 15 minutes ago a piece of my tooth enamel came off of my bottom right canine tooth where it meets my gum and another tooth. It was a fairly decent sized chunk and I didn't know what it was until I rubbed my tooth with my tongue. It didn't hurt, and it still doesn't hurt, but it has me worried because it looks like more wants to come off.
Anyone have an idea on what could've caused this? Should I see a dentist?
