Extreme Sensitivity to Hot, Cold, Pressure or Swelling

These symptoms could indicate that there may be some degree of nerve damage and the beginning of a tooth infection (abscess). Dental treatment does also place stress on the nerves of teeth and the nerves may not be able to recover.

Tooth cracks and extensive decay, along with having large fillings initially, increase the risks for permanent nerve damage by bacterial penetration into the nerve chamber. Root canal therapy or extraction can resolve the extreme sensitivity or discomfort of a tooth, when all other possibilities have been examined and ruled out by the Doctor.
