Toothache when drinking hot

Pain from hot drinks often reflects an irritated pulp, exposed dentin, decay, or a crack and needs assessment if it persists.

Heat can travel through thin enamel or dentin to the pulp, the living tissue inside the tooth. A brief response may occur with exposed dentin, while pain that lingers can indicate deeper pulpal inflammation.

Avoid very hot, cold, sweet, or acidic foods on that side, brush gently with fluoride toothpaste, and floss carefully around the tooth. Do not place aspirin, alcohol, or concentrated oils on the gum because they can injure tissue.

Arrange an examination if the pain repeats, lasts after the drink, wakes you, or is accompanied by swelling, a broken filling, or pain on biting. Facial swelling, fever, difficulty swallowing, or difficulty breathing needs urgent care.

Ask whether the pulp is involved, whether a crack or cavity is visible, and which tests are needed. Ask whether treatment could involve a filling, a protective restoration, or root canal treatment.
