1. At present, the main methods to treat dentin hypersensitivity are local drug treatment, laser treatment and restoration treatment. If it is tooth allergy caused by tooth wear and root exposure, it is difficult to cure it radically and easy to relapse.
2. Some folk remedies, such as chewing garlic often or rubbing allergic parts with fresh garlic three times a day, or chewing walnuts and tea, have certain desensitization effects. Because the main component of walnut kernel is linoleic acid glyceride, it can achieve desensitization effect, and tea is rich in tea polyphenols and fluorine, which can closely combine with calcium in teeth, enhance the acid resistance of enamel and increase the protective layer of teeth.
3. The best way to prevent dentin hypersensitivity and prolong desensitization is to reduce tooth wear and enhance tooth hardness. In order to reduce tooth wear, try to bite hard food as little as possible and stick to brushing your teeth in the right way every day. It is suggested to rinse your mouth with fluoride mouthwash and brush your teeth with desensitized toothpaste to improve the wear resistance of your teeth. Desensitization toothpaste should be used twice a day, and long-term use has certain effect.
Extended data:
The cause of tooth allergy should start with the structure of teeth. The feeling of pain when teeth are allergic basically comes from the dental nerve in the pulp. Under normal circumstances, dental pulp is wrapped by dentin, and dentin is wrapped by enamel. Enamel is a smooth, hard and dense substance, which is the most primitive and effective defense line of teeth.
Dentin itself has many tiny holes. In this way, if the enamel is damaged for some reason, external stimuli such as cold, heat, acid and sweetness will be transmitted to the pulp through these small holes, resulting in a feeling of pain. In addition to wear and tear, dental caries, acid erosion, tooth trauma, gingival atrophy in middle-aged and elderly people, root exposure and other reasons can also lead to tooth allergies.
