Okay, so last night I used this new mouthrinse I bought: Crest Pro Health Complete Rinse, and over night I've been waking up because they are literally burning (gum and tongue), and it's my b-day today and whatever I eat or drink won't get rid of the burn. It really feels like its on fire (not like spicy food on fire) but it is really painful!!!!! Help me, and how can I get rid of it?
