Q. Please please can you help I have not seen a dentist for over severn years due to my fear. The last time I went to the dentist was Bristol dental hospital where they used general anesthetic. Since moving to swansea in south wales I have been searching high and low for a dentist that gives gas and air as I have had this previously. But I have not found a dentist anywhere that does it now I am getting really down about my teeth as i have a broken half tooth on my lower right side and a crumbling tooth on my lower left side and already have two missing teeth on the lower jaw and one missing on the top I dearly would like to have my teeth fixed as it is really making me miserable but my fear is so great due to an experience i had at a dentist when i was younger which involed them snapping the needle in my mouth that there is no way i will go with out the option of gas and air. Please please help me.
