sounds like you have a bad infection.... need to see a dentist asap before it spreads like she said.....
alot of dentist will work out a payment plan for you
You need to see a dentist regardless of if you can afford it or not. You could try a school or sometimes there are pay-scale clinics in big cities. There is nothing that you can do to help the tooth, you need a dentist. Also, its a serious infection that you absolutely cannot overlook. It can spread to your blood stream and cause you to become septic for one thing.
