Katy, that is just awful. I'm sorry this is happening to you.
I've had similar situations. What I do is this: YOU decide if you need a r/c yourself. How? By determining how much discomfort you are willing to put up with ! Right now I have a back molar. It is not infected. It just aches with chewing sometimes with some kinds of foods. If it became Really uncomfortable to chew on I'd get a r/c. Just Hate to spend that kind of money !
Rub an ice cube with a Q tip. Then, looking in a mirror, put the cold tip on the tooth YOU think is the one. You'll know; trust me. The usual rule is if a tooth hurts more than 5 seconds after cold touches it then is removed you "need" a r/c. Like, if it hurts for 30 seconds you "need" one.
