Please don't be so fearful of the dentist. Anything they do that would be painful is numbed so you don't feel a thing while the work is being done. The longer you put it off the worse it will be and the more expensive it will be. I do not have dental insurance and hate those bills, but my teeth mean more to me so I will give something else up to pay the bill. Let your dentist know how you feel and he might suggest a small dose of valium or some such thing to help calm you before you go in.
