Fear is very easy to overcome. If you can't come right away and do what you want, like get a tooth fixed, then do it gradually. Take a friend for moral support. Come to the dentist you like, talk to him, take a look, get used to the environment, reach a certain threshold, a certain boundary you know, and go home. Next time you come in the same way, have a chat, sit in the chair, talk to the doctor, and go home. And so on, little by little. As they say...If you can't eat an elephant all at once, slice it up.... At the clinic, just tell them what your problem is and they'll help you. They've had people like that before. That way you'll gradually get over your fear and you'll be stronger....
