How to deal with toothache caused by cold, hot, sour or sweet

In daily life, many people have experienced toothache when eating hot, cold, sour or sweet foods. This is mainly caused by tooth allergy, and the causative factor is not very clear. Hot, cold, sour and sweet foods are the most common in the diet. If you cannot eat these foods, there will be fewer food choices, which will have a great impact on your normal diet. So, what should you do if your tooth hurts due to cold, hot, sour or sweet food? Let’s take a look below.

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.
