I am 19 years old and I have had almost 20 cavities filled. I am not kidding. I beat my dentist up when I was 7 because he wanted to take an x-ray, I wasn't having it! So I think i've come a long way since then, I still get nervous when I go, but I get over it once I get in the hot seat. I have very sensitive teeth and I hate just having my teeth cleaned, because my teeth are so sensitive. My advice is to find a dentist that you feel comfortable with, that you know other people have gone to, and had good experiences with. Tell them up front that you are very uncomfortable, and if it's because you are afraid of pain, ask them to give you novacaine. I am going to do that from now on when I have my teeth cleaned. And ask them to explain what they are doing. I have to have my wisdom teeth extracted next month and I am very nervous, but I know that it has to be done. I found a good oral surgeon that people I know have gone to, and had good experiences with. Good luck and don't be afraid, there are ways to work around things!!!!
