Why do you have toothache in winter?

In winter, the climate is cold, and teeth are easy to be allergic and sore, especially for middle-aged and elderly people with worn teeth and wedge-shaped defects in their necks. Eating sweet and sour foods such as apples, grapes, oranges and sweets will cause toothache, and some of them are too painful to eat. The following methods can be used to prevent and treat this allergic toothache: 1. Brush your teeth with warm water and rinse your mouth with warm tea: because the pulp nerve is sensitive to temperature, especially the teeth with worn teeth and exposed dentin, it will cause toothache when exposed to cold stimulation. Warm water is a natural protective agent for teeth and can prevent allergic toothache; Tea contains fluorine, and frequent gargling with warm tea can protect teeth, prevent dental caries and treat toothache. Second, the diet should be warm, don't eat too sweet and sour food, because teeth are most suitable for metabolism in a weak acidic environment with oral temperature of 35℃-36℃ and PH value of about 6.8. If you eat a diet with a large temperature difference between hot and cold or irritating food that is too sour and sweet, it will cause toothache. Third, brush your teeth with desensitized or acid-resistant toothpaste. Both toothpastes contain fluorine, which can prevent teeth from dephosphorization and decalcification in acidic environment, and have the functions of anti-acid, anti-aging and pain relief. 4. Rubbing garlic to relieve pain: For those with severe tooth wear and obvious sore surface, raw garlic can be used to rub sensitive parts repeatedly, twice a day, for 1-2 minutes each time, and the pain is obviously relieved or disappeared after 1-2 weeks. 5. After eating acidic foods such as vinegar, yogurt or sour fruit, if the teeth are sour, you can chew them with walnut kernels in your mouth, because walnut kernels are alkaline foods, and chewing slowly can neutralize the acidic substances on the tooth surface, so that the teeth will not be sour.
