Sensitivity to hot or cold can cause sudden discomfort when eating, drinking, or breathing in cold air. The sensation may be brief or linger after the trigger is removed.
Temperature-related discomfort like this is covered in our Common Concerns section, which explains common dental symptoms and when professional advice is helpful.
