You wince as the first bite of your ice cream cone causes a small explosion of sensitivity in your mouth. Not another cavity, you think to yourself. But as the day and the night wear on, the pain becomes worse. You start to feel it in your jaw and your neck. You?ve had a bad cavity before, but nothing like this. Instead of waiting for an appointment with your Invisalign dentist , you head to the emergency room to see the dentist there. You?re taken in and treated right away, after which the dentist explains to you everything you never wanted (but needed to know) about dental abscesses.
