I have seen number of patients that suddenly have generalized teeth sensitivity after use of tartar control formula tooth pastes. The reason for this sensitivity that goes away after the use of the tooth paste is stopped is due to the anticalculus component of the tartar control dentifrice. Tetrasodium and /or Tetrapotasium Pyrophospahate are the chemical names of these tartar control components. Pyrophosphates alone are not responsible for hypersensitivity. In order to mask the strong bitter taste of pyrophosphates concentration of flavoring agents, known to cause sensitivity are increased. Also increased concentration of detergents is needed to make Pyrophosphates soluble in the dentifrice. These changes are the causative factors in hypersensitivity reactions. Teeth restored with restorations like porcelain veneers should not have sensitvity.
