2021-04-28
Tooth sensitivity is not inherent, but is caused by exposure of dentin. When the dentin is exposed, we will see many small holes in the dentin under the microscope. The teeth feel external stimulation through these small holes, which causes tooth sensitivity.

What causes the dentin exposure?

1, cracked teeth

Tooth cracks are small, hard-to-find cracks that occur on the surface of the crown. Tooth cracks are caused by internal factors of the tooth structure and external factors such as excessive chewing force. There are no symptoms in the early stage of cracked tooth. As the crack deepens and affects the dental pulp, it will cause soft teeth and painful bite. Spontaneous pain will occur when the dental pulp is infected, and eventually the tooth will be lost.

2, dental caries

If you have dental caries, and you have a soreness when brushing your teeth, drinking hot water, or chewing food, it means that the dental caries has developed to a moderate depth. When the dental caries develops deep and close to the pulp, the sensitivity symptoms will be obvious, even in the Pain occurs under the stimulation of cold and heat.


3, tooth wedge-shaped defect


Incorrect brushing method will mechanically damage the neck of the tooth, resulting in defects, exposing the dentin, and being exposed to external stimuli, especially sensitive symptoms when the temperature difference between hot and cold changes.

4. Periodontitis

When periodontitis progresses to the middle and late stages, the alveolar bone is resorbed, causing the gums to shrink and the root surface of the tooth is exposed. However, the root surface of the tooth that loses its protection is prone to sensitive symptoms, multiple teeth or feeling full teeth under the stimulation of cold and hot temperatures. The neck is sore and weak, and the teeth will feel visibly weak when biting.

5, acid reflux tooth sensitivity

Gastrointestinal diseases can also cause teeth to become sore. This is because the refluxed gastric acid corrodes the teeth in the oral cavity and causes the surface of the teeth to decalcify. As a result, the teeth are susceptible to external stimuli and feel sensitive.

6, menstrual period tooth sensitivity

is common in young women, and may be related to the impact of changes in hormone levels during menstruation on the oral environment, or mental anxiety during menstruation.
