i have a good deal going with my dentist,we trade labor i replaced 5 8ft frenchwood sliders(labor only)+in return i recieved 2 gold crowns+a root canal.origanaly he was like you need this +that +one of those,it'll be 3400.00. so i was like how about you just rip them out,i can't afford that doc i have priorities,i need a stroker motor! the kicker was i just went in for a routine cleaning+had no idea i needed a major overhaul,at least if it hurt +he fixed it i would have felt like i got my moneys worth.3 1/2 hours in the chair,big fun.
