What causes tooth sensitivity and how to solve it? This article will answer these questions.

Many people feel a sour sensation in their teeth when eating刺激性 foods. What is going on? Experts say that tooth sensitivity is a symptom of dentin hypersensitivity. The cause may be a lack of enamel exposing the dentin, poor enamel calcification, or long-term chewing on one side of the mouth, leading to excessive wear on that side. In addition to regular brushing and common oral cleaning methods, there are a few tips to prevent and treat dentin hypersensitivity.

For example, patients can chew raw walnut kernels, or repeatedly rub the sensitive areas of their teeth with a cross-section of fresh garlic. Garlicin has antibacterial and anti-inflammatory effects and can help with dentin hypersensitivity. Raw walnut kernels are rich in tannic acid, which can coagulate the protein in dentinal tubules and also have a desensitizing effect.

Another simple and convenient method is to use tea, which is easy to find everywhere. Do not throw away leftover tea; you can "reuse" it by placing it in your mouth, especially on sensitive teeth, and chewing it. You can also directly place fresh tea leaves on sensitive areas and gently chew. Research shows that tea is rich in fluoride and tea polyphenols. Tea polyphenols have disinfecting and antibacterial properties. They can inhibit the growth of cavity-causing bacteria and enhance the acid resistance of tooth enamel. When fluoride is also present, the acid resistance is unexpectedly enhanced. In addition, the fluoride ions in tea have a good protective effect on teeth. They have a strong affinity with the calcium in teeth, which is like adding a protective layer to the teeth.

When using chewing tea leaves to treat tooth sensitivity, there is no need to choose high-grade tea, as high-grade tea actually contains much less fluoride than lower-grade tea.

The methods above are remedies after tooth sensitivity occurs. In fact, they are also useful for preventing dental problems. Of course, drinking tea regularly can also help maintain dental health. In addition, to prevent dentin hypersensitivity, it is best to chew with both sides of the mouth to avoid excessive wear on one side, and it is advisable to eat fewer hard foods.
