It sounds like you have some kind of dental abscess. You may want to contact your local dental society or go to a local dental school to get it treated for a lower cost.
thanks anyways im gonna try n do the salt water thing n listreain
The salt water rinse may help to drain some of the pus out and relieve some of the swelling but it won't resolve the underlying problem of an infection. Without proper treatment, the situation will gradually worsen and you may end up losing that tooth. I still recommend seeing a dentist to find out whats going on.
