How does dental varnish work?

How fluoride varnish works. It slows down the development of decay by stopping demineralisation. It makes the enamel more resistant to acid attack (from plaque bacteria), and speeds up remineralisation (remineralising the tooth with fluoride ions, making the tooth surface stronger and less soluble).
