Phoenix abscess...as in the phoenix bird in greek mythology which comes back to life from its own ashes...or more relevantly, the name of Jean Grey when she returns from the dead in the X-Men comic books

but in all seriousness, a phoenix abscess is when you have an acute flare-up of a chronic, low grade lesion (i.e., what you have right now)...basically, when the tooth ache comes back to life after beign dormant for a while
