[/INST] 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 rinsesabscess - bacteria into nerve, requires root canal therapycracked tooth or root - X-ray, observation, treatment options depend on extent of fractureLook 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. </s>
