So far, the dentist has been unable to permanently seal the
tooth. Each check still shows some
pus. He does his thing with the files, and puts in another temporary filling. This has happened 3 times. Meanwhile, the tooth hurts to bite down on, and I can feel my heart beat in it. Its getting more uncomfortable instead of better. I'm due for a 4th check in several weeks. The dentist said that this isn't that unusual. I've never heard of anyone else experiencing this.
