...wisdom teeth. (pics included!)? I'm looking for advice on teeth in general. Ahead of time, let me say I know I need to go to the dentist, I'm heading there next week to get a referral to get my wisdom teeth out... I can't afford anything else right now.
First off is my wisdom teeth. See them here http://i26.tinypic.com/2gxmal3.jpg
My upper right is heavily deteriorated, and is the main problem tooth. There's little left of the tooth, and the gum on the outside of the tooth has become loose and tender (only to the touch), most likely because there's so little tooth there now. I do my best to keep and clean, and have been using Listerine a few months now. Can Wisdom teeth push other teeth out of place?
My teeth used to be perfectly aligned (even my dentist said so), but I've noticed something wrong... I'm the type that tears things open with my teeth, or making little punctures with them. I mean my canines, of course, and they just don't meet anymore! This has only been in the last few months, and it's really frustrating... my bf and I like to nip at each other ;P and I can't even do that anymore. Also, there's a gap where there never used to be one.
