Desensitising gel is a unique, sustained release gel. It is a 3% potassium nitrate and 0.11% weight by weight fluoride ion, sticky, viscous gel. Designed to be used in a custom-fabricated tray. Indications: Desensitising gel provides a film-like varnish for sensitive teeth, sealing dentinal tubules in exposed dentin and other areas where post-operative sensitivity is a concern. The product is used either by a dental professional in the surgery or provided to the patient for home treatment of dentin sensitivity.
