i have a receding gum line. i've got something stuck somewhere, and it's agony. there's a sore on the roof of my mouth. the only way to aleve the pain is to put cold water in my mouth. when i don't have the water in my mouth, it burns, and my teeth ache. i've been doing it all weekend (no sleep). i'm calling a dentist tomorrow. is there something else i can do for the pain?
