I have a private dentist. It is a cap at the front, been there since 1995, never one bit of bother, but last week i noticed it felt rough, and it has a bit of a crack from the bottom! eek! I have a dentist appointment Thurs. Can anyone tell me what they do. Do i need a new one. How much will it cost, or does the private cover it (denplan). Or am I better looking for an NHS one. Thanks
