So last March I had a root canal done, but the dentist didn't want to put a crown on it because of my wisdom teeth growing underneath--so he recommended that I had them extracted, which I did. (This is the lower part of my mouth, the last molar). That cost me about $1200. Anyway, after having that done, my insurance said I wasn't eligible for a crown until January of 2012. I saw the dentist in August about maybe having it done, not realizing that my tooth had broken off a bit. He said that it was fine and not to worry about it, and just not to chew anything hard on that side, but that if the tooth were to split vertically, in two, to call him. Well, I left for school.. (I am originally a resident of California, going to school in Oregon), and was enjoying my college-student dinner of Ramen Noodles, when I noticed that even more of my tooth had broken off. Basically, half of it is now gone (I can see where the root was filled--kind of has a pinkish look to it), as it has split off even more. I can see the bottom of it, sort of, and I don't think it has split in half, but it has left this giant gaping crater in my tooth down to the gum line. I won't be back in California UNTIL December/January when I can get the crown finally done, but am wondering what I can do for now? It doesn't hurt at all--obviously because the root has been extracted, but I'm wondering should I put some kind of dental cement on it to stop the root filling from falling out... or what? What options do I have? Also, will they still be able to put the crown on it, or will the tooth have to be extracted? (A good half of it still remains standing). Thanks!
