A. Hi, It’s hard to answer your question as you don’t even know yourself why you have a fear of dentists. It is a very common fear which is usually brought on by bad experiences. Sometimes people develop a fear because of things they’ve heard they’re parents or others say whilst they were young. It could also be because you have not found a dentist whom you trust. Have you tried taking sedative drugs such as Valium before your appointment? I think the key is to talk find a dentist you trust – perhaps through a reference if you don’t trust your current dentist and see what they can suggest.
