Our Technologies

The Dentin contains microscopic tubules (small hollow tubes or canals). When the dentin loses its protective covering, the tubules allow heat and cold or acidic or sticky foods to stimulate the nerves and cells inside the tooth. This may cause hypersensitivity.

SirinMED products and technologies are focused toward the idea of reducing that pain.
