What is dental hypersensitivity? Many people experience sudden, transient pain when their teeth are subjected to temperature, blowing, mechanical or other chemical stimuli: and it cannot be attributed to any other form of dental defect or lesion. This is what we often refer to as dentin hypersensitivity. Here is a brief explanation of the mechanism by which dentin hypersensitivity occurs: it is due to stimulation of the exposed dentin and changes in the flow of fluid in the dentin tubules, causing elongation and compression of the cells and protrusions, stirring the pulpal nerve and producing pain. There are many causes of dentin hypersensitivity, which are mainly attributed to the following: 1. Such as poor enamel development calcification. Tetracycline teeth. 2, grinding teeth. Frequent use of one side to eat hard things. 3, often eat highly acidic and irritating food. 4, gum recession. Excessive stomach acid, neurosis patients. 5. Use a toothbrush with too hard bristles or use too much force to brush your teeth. Although dentin allergy is not a very serious oral disease, but because of the sensitivity has led to a decline in the quality of life, many things dare not eat, even when brushing teeth have pain. Moreover, if this allergy is not treated in time, it may eventually lead to irreversible endodontic diseases such as pulpitis and periapical periodontitis. We have seen many similar patients in the past and suggested to buy desensitizing toothpaste for desensitization and not to eat too hot or cold food. But the effect is not very obvious. Recently, we introduced a more advanced desensitizer, Orwell Dental Desensitizer, to our department. It is a toothpaste-like gel that closes the exposed dentin tubules through a remineralization mechanism to achieve desensitization. It can be used not only for dentin sensitivity, but also for gingivitis, periodontitis and other antibacterial and anti-inflammatory purposes. It is easy to use, just apply it to the sensitive tooth area for 1 minute after brushing every day, then rinse your mouth after 3-5 minutes. It is not dangerous to swallow and can be used by pregnant women and children. It works relatively quickly and has a long-lasting effect, and most patients have very noticeable results after the first use. Therefore, do not ignore dentin sensitivity, and people who have this symptom now are advised to visit a professional medical institution as soon as possible for timely treatment.
