Tooth hypersensitivity requires desensitization treatment, commonly used is fluoride. Tooth allergy is a common symptom, mostly seen in hot, cold and sweet allergies. The outermost part of the tooth is the enamel, and once the enamel is worn away, it exposes the dentin inside, which has many dentin tubules leading to the pulp tissue, and the hot, cold and sweet can cause pain and discomfort. Tooth hypersensitivity requires desensitization treatment, which can be applied with Dulux fluoride. It can seal the dentin tubules and reduce the irritation of the pulp tissue from hot and cold. Alternatively, dentin tubules can be closed with sodium fluoride, or muscimol. Tooth hypersensitivity can also be caused by hot and cold hypersensitivity if the teeth are incorrectly brushed, such as a wedge-shaped defect in the cervical region of the tooth after horizontal brushing, reaching the dentin layer. This condition can be treated with filling of the tooth. Pulp preservation can be done with calcium hydroxide followed by resin restoration to insulate the tooth from external hot and cold stimuli. Dental allergies can also be desensitized through dietary therapy, such as chewing tea or walnuts. Or chewing garlic, slicing it and then applying it to sensitive areas to achieve relief from dental discomfort.
