Lingering pain after eating hot or cold foods and liquids?

 

Possible problem: This probably means the pulp is inflamed and/or dying, and may be irreversibly damaged usually as a result of deep decay or physical trauma. What to do: Please book an appointment ASAP to see an periodontist to diagnose the problem before the pain becomes severe due to the development of an abscess. The tooth will likely need root canal treatment to remove the dying or dead pulp tissue to save the tooth.
