Hello,
Common causes for post filling sensitivity:
High bite - needs adjustment
Close to nerve -
hypersensitivity may decrease with time, reduce use and extreme temperatures, use toothpaste for sensitive teeth,
fluoride rinses
abscess - bacteria into nerve, requires
root canal therapy
cracked tooth or root - X-ray, observation, treatment options depend on extent of fracture
Look for swelling, increased pressure and hot sensitivity for an indication of infection. Mobility can indicate a fracture or infection. Monitor and report your symptoms to your
dentist. Take some anti-inflammatory medication such as tylenol or advil to reduce discomfort from the initial possible discomfort due to the dental procedure.
Cold sensitivity is less of a concern and time may reduce sensitivity. Check that filling did not chip or crack.
Thank you for your inquiry. I hope you will start to feel better soon.
