Where does the tooth feel come from?

First, let's understand where the feeling of teeth comes from.

The structure of the tooth can be divided into three parts from the external shape: the crown, the neck and the root. The crown is the main part of the chewing function, and the shape of different teeth is different. The root of the tooth is buried in the alveolar bone and is the supporting part of the tooth. The neck is the arcuate part where the crown meets the root.

The structure of teeth can be divided into enamel, cementum, dentin and pulp according to histology. Enamel is the translucent white hard tissue covering the surface of the crown, cementum is the mineralized hard tissue covering the surface of the root, dentin is the hard tissue that constitutes the main body of the tooth, and the pulp is located in the pulp chamber composed of dentin , is the only soft tissue in the tooth tissue.

The reason why teeth feel sensitive is because the pulp tissue is stimulated by the outside world. Under normal circumstances, the teeth do not feel any sensation when eating cold, hot, sour and sweet due to the protection of the enamel. If you encounter sweets or cold water soreness, it is likely that the dentin is exposed, and the stimulation is transmitted to the pulp, causing this discomfort, and this discomfort itself is also a reminder that there is a problem with the tooth.

Tooth sensitivity may be caused by a variety of reasons, and there are different solutions for tooth sensitivity caused by different reasons:

1. Whether there is dental caries

In the presence of caries, the pulp can easily come into contact with external stimuli, which can cause tooth discomfort. If it's just a simple hole, don't panic too much, just ask a doctor to repair it. But if the tooth decay is deep, it may damage the pulp, and root canal treatment is required to remove the infected tooth nerve before filling or crowning.

2. Whether there is periodontitis

The occurrence of periodontitis is mostly related to dental plaque and calculus, which is inflammation caused by poor oral environment. Periodontitis can cause the gums to recede and the root surfaces of the teeth to be exposed, exposing the nerves of the teeth. In addition to symptomatic anti-inflammation, it is especially important to keep the mouth clean in the treatment of periodontitis. In addition to brushing your teeth every morning and evening and rinsing your mouth after meals, you should also develop the habit of cleaning your teeth regularly.

3. Whether you have dentin hypersensitivity

Many people, especially the elderly, chew a lot of hard objects, which causes excessive wear on the tooth surface and causes dentin sensitivity. For such a situation, you can usually choose some toothpaste with desensitization effect to help reduce tooth sensitivity, and try to avoid chewing on the affected side when eating.

Tooth sensitivity is not a single disease, but a common symptom of tooth defects caused by various reasons. The common causes of tooth defects include abrasion, trauma or improper brushing, which cause wedge-shaped defects, etc., which damage the enamel and cause dentin exposure. External stimuli Symptoms of tooth sensitivity are transmitted through the cytoplasmic processes of dentin and odontoblasts.

Or due to certain systemic diseases: such as menstrual period and pregnancy, the stress of the whole body increases, and the sensitivity of nerve endings increases. Even if the dentin is not exposed, the teeth of the whole mouth will feel extremely sensitive and uncomfortable.

Five ways to save sensitive teeth

In addition to using desensitizing toothpaste when brushing your teeth, if it is a little serious, you can also apply desensitizing toothpaste directly on sensitive teeth~
