Many people experience an acidic sensation in their teeth when they eat stimulating foods. What's the reason for this? Deputy Director of the Department of Stomatology at Beijing Shijitan Hospital, Wang Lixin, introduced that the acidic feeling in teeth is a symptom of dentin hypersensitivity. The cause could be due to enamel deficiency leading to exposed dentin, or poor development and calcification of enamel. It could also be due to long-term use of one side for chewing food, causing severe wear on one side of the teeth. To prevent and treat dentin hypersensitivity, in addition to common oral hygiene practices such as brushing teeth frequently, there are a few small tricks that can be used.
For example, patients can chew on raw walnut kernels, or repeatedly rub the cross-section of fresh garlic on the sensitive areas of the teeth that feel sore. Allicin has antibacterial and anti-inflammatory properties and is effective in treating dentin hypersensitivity. Raw walnut kernels contain large amounts of tannic acid, which can coagulate proteins in the dentinal tubules, thus playing a role in desensitization.
There is another simple and convenient method: using tea that we see everywhere around us. Don't discard overnight tea arbitrarily; you can "recycle" it by placing it in your mouth, especially on the parts of the teeth that are sensitive. You can also place fresh tea leaves directly on the sensitive areas of the teeth and chew them gently. Studies have shown that tea contains abundant fluoride and tea polyphenols, among other components. Tea polyphenols have disinfectant and bactericidal effects; they not only inhibit the growth of caries bacteria but also enhance the acid resistance of enamel. Moreover, under the participation of fluoride, the acid resistance ability will unexpectedly increase. Additionally, fluoride ions in tea have good health care effects on teeth, with a great affinity for the calcium in teeth. This is like adding a protective layer to the teeth.
Director Wang said that when using the method of chewing tea to treat toothache, there's no need to choose high-grade tea because the fluoride content in high-grade tea is much less than in low-grade tea.
All of the above methods are remedial measures after the teeth become painful, but they are also useful for preventing dental diseases. Of course, drinking tea regularly can also play a certain role in dental care. Additionally, to prevent dentin hypersensitivity, it's best to chew food with both sides of the teeth to avoid excessive wear on one side, and it's best to eat fewer hard foods.
