Ok I'm trying to get my back two molars taken out but I don't have insurance .. and since this is going to be my first visit to the dentist in a long time they said x rays and check up will cost 78 bucks but that's the thing I'm tight on money is there anywere were you can just pay to get your tooth that's bothering you removed without going trough the whole x ray thing .. also I don't want to be put to sleep so how much would laughing gas cost?
