I've been playing for 15 years now and I've noticed that my front bottom teeth are starting to chip and flake away. Today a large chunk fell off the back of one of them - resulting in a trip to the dentist tomorrow (Tuesday 5th). Could this be as a result of playing? (ok, so I know this would mean I'm doing it wrong - don't make me feel any worse than I do!) Has anyone experienced the same? Is it just me? Any hints or tips? I'm very proud of my teeth - no fillings and I brush every morning and night! I hate something being wrong with them.
