My Gum has Turned Grey Above the Tooth line and they are very sensitive.
Does that mean that my teeth are decaying? I can not afford to go to a dentist right now. My teeth seem fine, but they are all very deeply pitted right around the gum-line from what I can see. Not sure want to do? I been brushing my teeth three times a day now and flossing at least twice a day with no improvement. How can I get some dental help for this issue?
