Used to treat hypersensitivity by using the elements that are naturally found in the tooth, (Calcium & Phosphate) and restoring them to the tooth in the form of Hydroxyapatite plugs that quickly block the open tubules. The Calcium & Phosphate continue to release therefore causing mineralization to occur and further seal the tubules. Treats exposed roots after perio surgery, bleaching procedures, scaling and root planning, and hypersensitivity due to gingival recession
