Molar with root canal in 2004. Cap came off in May 2011. Tooth underneath had fallen apart and decayed sig due to leak in cap over years. No cap since (not getting my dental insurance till sept 1st). Last few days the exposed gum area around the remaining tooth has become very sensitive to touch. No actual pain on the remaining tooth because roots were removed. Gum area closest to cheek appears slightly swollen, but just barely. Is my gum infected? If so, how long can I wait. Made appt with dentist but soonest they can see me for consultation is week and a half. Is this too long? Could this problem grow sig worse if I wait this long?
