The unique symptoms of dentin hypersensitivity are mainly the feeling of weakness or pain in teeth when eating sour, sweet, cold and hot food. Therefore, people who have "sour teeth" are often reluctant to eat fruit with sour taste, and they are not willing to eat sweets, and they are even more reluctant to rinse their mouths and brush their teeth with cold or hot water.

So, how to prevent "acid tooth"?

1.Eliminate the factors causing dentin hypersensitivity. For example, grinding teeth at night is an important cause of enamel wear and dentin exposure, which in turn causes "acid teeth"; Bad brushing methods make teeth age suffer from mechanical friction, which leads to gingival atrophy, root exposure or wedge-shaped defect in the neck of teeth, which is also the cause of "sour teeth". Therefore, active prevention and treatment of nocturnal molars and correct brushing are effective measures to eliminate dentin hypersensitivity.

2. Choose sodium fluoride or desensitized toothpaste to brush your teeth twice a day for 3 minutes each time. In addition, 3% strontium chloride solution is commonly used to gargle the desensitizing agent, which is gargled 3-4 times a day for 3 minutes each time, so that the liquid medicine can fully contact the tooth allergic area.

3. You can rub or chew tea and walnut meat with garlic. These methods are all good methods that have been circulated among the people and affirmed after being tried by everyone.

4. Go to the hospital for treatment. Desensitization with iodophenol by diathermy, once a week 1 time, generally 2-3 times can be effective; 75% sodium fluoride paste can also be used to smear allergic teeth. Fluorine or calcium iontophoresis can also be used to treat "acid inverted teeth" caused by decalcification of most teeth or whole teeth.

5. If the above methods are not effective, individual cavities can be prepared in sensitive areas and filled with filling materials; Crown can also be used to isolate the stimulation of the factors that cause "acid teeth".
