Fluoride is also now thought to act locally on the tooth enamel, altering the remineralisation - demineralisation balance in favour of remineralisation.
  • Inclusion of a fluoride source is also desirable when a polyphosphate anti- calculus agent is included, in order to inhibit the enzymic hydrolysis of such polyphosphates by salivary phosphatase enzymes.
