Dr.Collins BioMin® Restore Toothpaste® contains BioMin® C, a patented ingredient combination of calcium, phosphate, silica and chloride, that is an integral component of the DR COLLINS BIORESTORE™ Complex. When BIOMIN® C comes into contact with saliva, it creates BIORESTORE™ (hydroxycarbonated apatite), a chemical that is structurally similar to tooth mineral. BIORESTORE™ is able to attach and seal porous tooth structure, thereby reducing tooth sensitivity. BIOMIN® RESTORE TOOTHPASTE® is a fluoride-free toothpaste intended for cleaning the tooth surface on a daily basis. The toothpaste is formulated to provide rapid and continual desensitization through mechanical occlusion of exposed dentinal tubule.
