hi there i know exactly how u feel, i am sure many of us do on this forum. the advice from missbelle is spot on...I have serious dental anxiety and i found some a forum called dental fear central which helped me. There are dentists on there who will answers your questions too. Please try not to worry i know thats easier said than done but u are definitely not alone with this, and u can ask people u know if they can recommend a good dentist, that might reassure u a bit. good luck, you're gonna be fine
