How badly did you chip it? It is is cracked way down into your tooth - you might want to go see a dentist...if the nerve gets exposed you will have a whole different problem and it won't be pleasant...

But if it is not chipped that deep then by all means file away.... I have a Dental plan so It doesn't cost me when I go to the Dentist for stuff like that anyways... So I would have a professional do it...

Your not afraid of the Dentist are you Cryptic??
