Topical oral gel dentifrice formulated with calcium magnesium phosphate and potassium nitrate to protect against sensitivity. Unique desensitizing gel alleviates tooth sensitivity and discomfort by delivering nanosized calcium phosphate minerals to the tooth surface, occluding and penetrating deep inside the dentinal tubules. Patented microsphere technology reacts with saliva to deliver mineral-forming calcium phosphate ions. Does not contain any milk-derived proteins, so it is safe for all patients. Low-abrasion formulation does not harm the enamel surface.
