Hello you wonderful people of the interwebs. Can ignored toothaches mess you up? I had a toothache recently, ignored it for ages, but finally went to a dentist. There was a cavity, which the dentist removed--but perhaps not fully. She said the decay looked quite deep and she tried to remove "as much of it as she could"--any further and she might hit the gum--and she put a filling in. So she said give it 6 months and come back. 6 weeks later, the tooth is still pretty damn sensitive. Like, SHARP pain when I drink cold water. 6 months is too long to wait. Could this be making me ill? I've been feeling crappy lately, under the weather, groggy, not myself.
