Shana, I am sorry about your tooth! Hope you get it taken care of very soon! Plus, if you find a dentist that will do a crown for $400 I want his name, address and phone number!
I just paid over $600 for a crown...no root canal...just a crown. My tooth was cracked and the filling leaked and hurt...so he crowned it and it is great...with your teeth, tho...you DON'T want to put it off. Make them give you some gas to calm you down.
