I need help with the most accurate pricing or the best possible route, but I currently out of the job with no insurance and with my first cavity ever. Ive never had a problem with my teeth other than they never fully whiten but I'm noticing a hole in my left front molar with a slight black and browning. Im assuming a cavity but there is zero pain or discomfort. I'd like to know what the cost of fix would be? Ive called several places but they keep saying "Oh well it really is a wide range of pricing." Or "Sorry we're booked till july.". If this starts hurting is there really no type of emergency room / get in today places for dentist?
