There are two main reasons for dentin allergy: first, there are nerves in the teeth, which are more likely to be excited and sensitive, which is one aspect; On the other hand, the tooth nerve is not in direct contact with the outside world, and there is a layer of teeth in the middle. There are some tubules on the teeth called dentinal tubules, which are connected inside and outside. If the permeability of tubules increases, coupled with external stimuli, it will cause nerve excitement and make people feel pain.
Therefore, desensitized toothpaste can alleviate the symptoms of dentin hypersensitivity, and can also reduce the sensitivity of nerves through these two aspects, so that nerves are slightly dull and patients are not prone to pain; There is also desensitizing toothpaste that forms a layer of deposits on the surface of teeth, blocking dentinal tubules, such as channels that communicate with the inside and outside of teeth. After blocking, the teeth will become dull when exposed to this cold and hot stimulus. It is equivalent to putting a coat on a person to make him feel cold less easily. These are the two elements of the main desensitizing toothpaste used to relieve dentin hypersensitivity.
