What to do if your tooth hurts when you eat hot or cold food

Toothache after eating hot or cold food is mainly caused by tooth allergy. Although the cause is not very clear, you will feel sore and painful when you eat hot, cold, sour or sweet food. For some people, it happens occasionally, but if it happens frequently, they cannot eat what they want, and cannot eat many things, which is very painful. So, what should you do if your tooth hurts when you eat hot or cold food? Let’s look at the solution below.

Tooth sensitivity, medically known as allergic dentin or dentin hypersensitivity, is a symptom of pain caused by external stimuli such as temperature (cold, hot), chemicals (acid, sweet) and mechanical action (friction or biting hard objects). The main treatments for tooth allergy include local medication, laser treatment, and restorative treatment.

Tooth sensitivity and pain , clinically known as dentin hypersensitivity, is a symptom of pain caused by external stimuli such as cold, heat, sour, sweet food, and biting hard objects such as walnuts and pine nuts. By examining the tooth surface with a probe, one or several sensitive areas can be found, which are characterized by rapid onset, sharp pain and short duration. Patients often experience pain when talking, being blown by cold wind, or accidentally biting a certain point of the tooth while eating, which will be relieved after a while. Dentin hypersensitivity can occur in a single tooth or in multiple teeth. Dentin hypersensitivity can be caused by any dental disease that destroys the integrity of the tooth enamel and exposes the dentin, such as abrasion (frequent biting of hard objects, such as walnuts, bones, etc., and bruxism at night), tooth fractures caused by trauma, wedge-shaped defects in the tooth neck caused by long-term improper brushing, caries, and periodontal atrophy leading to exposed tooth roots.
