Ok I need advice! I think I know what I need to do, but second guessing myself. Leslie has a tooth really 2 that the orthodontist has been working on root canals since September. We'll the one that was doing good is abbcessed and her jaw is swollen and the whole side of her head hurts. The ortho doesn't come in until 1 or 2, her pediatrician doesn't have any appointments left for today. So should we go to ER or urgent care?
