I hate dentist's help!!!?

I have a real phobia of dentist's but i have horrible teeth.. most of my back teeth are none existant because they have cracked and got infected as i'm to scared to go to the dentist.. the same has begun to happen with my top front teeth.. i decided i would go to the dentist a couple of months ago but i get a dry mouth and feel like i cant breath and really panick i also dont like anything metal near my teeth not even a fork when i'm eating.. I really need to get them sorted as i feel paranoid like everyone stares at them when i smile and talk.. i think i might need false teeth as the front ones are startin to rot from my gums so they wont be able to be saved.. Does anyone know the quickest way to go about this and maybe a dentist that will put me to sleep?? I'm currently on the NHS but would be willing to pay a reasonable price as it is getting me so down and i cant even smile in public!!
