Hi, my name is Amanda, I woke up the other morning with my gum area behind my lower last molar swollen, hurting, and what feels like opening up right beside my last molar.. Very strange. I've been to the dentist a couple of months ago, took exrays and told me I have no wisdom teeth!! ;) woohoo right?! So... I'm pretty sure this has happened to the right side before and at that time the gum opened up and created a hole.. But no tooth.. Help. Please!!
