Healix Desensitizer Gel is a gel-based mixture of Sodium Fluoride and Potassium Nitrate. It provides a film-like varnish for sensitive teeth, sealing dentinal tubules of exposed dentin and other areas where post-operative sensitivity is a concern. The product is used either by a dental professional in the office or provided to the patient for home treatment of dentin sensitivity. It is not to be used as home use by patient.
