Pain when eating or drinking something hot can be a sign that the nerve inside your tooth is inflamed. A deep cavity, a cracked tooth, a failing filling, or an infection are some of the most common causes.
If the pain goes away quickly, the tooth may simply be irritated. If it lingers for several seconds after the heat is gone, it’s a sign the tooth should be evaluated.
The sooner we determine the cause, the more treatment options you’ll usually have.
