Anti-sensitivity toothpaste is clinically recommended for comfort toothpaste, which contains strontium chloride, and has a better effect on tooth sensitivity and relief. There are many patients who will have clinical symptoms of dentin hypersensitivity, when there is hot and cold stimulation or mechanical stimulation, there will be local soreness and discomfort, you can go to the clinical desensitization treatment, you can also apply anti-sensitive toothpaste in the usual brushing process to relieve tooth hypersensitivity. At present, the effect of comfort toothpaste is still relatively good, but patients with more serious tooth allergy may have poorer effect through treatment, and some of them need to come for root canal treatment or crown restoration. If the tooth allergy is not very serious, you can apply Comfort Toothpaste, but if it is very serious, you should come to the hospital for examination and treatment.
