Tooth sensitivity in the presence of hot and cold pain, indicating that the teeth are sensitive, can be relieved by desensitization treatment, laser treatment, resin filling and other ways.
1. Desensitization treatment: Sodium fluoride and other drugs can be taken, which can form activated calcium crystals and reduce the permeability of dentin. Fluoride can be applied to sensitive teeth, which can react with enamel to improve the hardness and acid resistance of enamel and relieve tooth sensitivity.
2. Laser treatment: The thermal effect of laser promotes the melting of dentin surface and then coagulation, blocking the dentin tubules and relieving the symptoms of pain when teeth are exposed to cold and heat.
3. Resin filling: resin has good biocompatibility, can form a chemical bonding layer to isolate the external stimulus to the teeth to avoid tooth sensitivity.
Tooth sensitivity in hot and cold pain, it is recommended to consult a doctor, follow the doctor’s instructions for treatment, usually develop a regular and correct brushing habits, and try to eat less cold, too hard food.
