Depending on the degree of sensitivity of the patient’s teeth, they may choose to be desensitized with a desensitizing toothpaste. Desensitizing toothpaste is usually used as a specific anti-sensitizing toothpaste by Comfort and also as a specific anti-sensitizing toothpaste by Cold Souring, both of which are effective against the effect of sensitivity. Depending on the patient’s self-perception, if he or she is slightly sensitive when eating cold, hot, sour or sweet foods, he or she can be desensitized with a desensitizing toothpaste. If the pain is severe or sharp when the patient is cold, the patient needs to go to the dentistry department of a regular hospital in time for examination and treatment by a doctor. In some cases, tooth sensitivity is caused by wedge-shaped defects, and if hard damage to the teeth has been caused, professional repair treatment is needed to relieve the symptoms of sensitivity.
