This toothpaste contains fluorine, which can prevent teeth from dephosphorization and decalcification in acidic environment, and has the effects of anti-acid, anti-aging and pain relief.

Second, chew walnuts.

If you have a toothache after eating acidic food such as vinegar, yogurt or sour fruit, you can chew it with walnut kernels in your mouth. Because walnut kernel is an alkaline food, chewing slowly can neutralize the acidic substances on the surface of teeth, so that teeth will not be sour.

Third, eat warmly and don't eat sour and sweet food.

Because teeth are most suitable for metabolism in a weak acidic environment with an oral temperature of 35℃-36℃ and a PH value of about 6.8, if you eat a diet with a large temperature difference between hot and cold or an irritating food that is too sour and sweet, it will cause toothache.

Fourth, rub garlic to relieve pain.

For those with severe tooth wear and obvious sore surface, raw garlic can be used to rub sensitive parts repeatedly, once a day 1-2 times, once 1-2 minutes. 1-2 weeks later, the pain will be obviously relieved or disappeared.

5. 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 can cause toothache when stimulated by cold. Warm water is a natural protective agent for teeth and can prevent and treat allergic toothache. Tea contains fluorine, and frequent gargling with warm tea can protect teeth, prevent dental caries and treat toothache.
