Problems With Dental Fillings
Tooth sensitivity following placement of a filling is fairly common. A tooth may be sensitive to pressure, air, sweet foods, or temperature. Usually, the sensitivity resolves on its own within a few weeks. During this time, avoid those things that are causing the sensitivity. Pain relievers are generally not required.
Contact your dentist if the sensitivity does not subside within 2 to 4 weeks or if your tooth is extremely sensitive. He or she may recommend you use a desensitizing toothpaste, may apply a desensitizing agent to the tooth, or possibly suggest a root canal procedure.
