My local GP actually recommended chewing Extea gum for a healthy breath freshener. Zingy minty burst of flavour that lasts quite a while. Would recommend to all

Wrigley’s Extra Active gum is handy in the handbag to have after a coffee and eating to freshen my breath,the flavour is fresh and clean.

Gotta love wriggleys chewing gum, but I find that the flavour does not last long after putting it into your mouth. And popping the pieces too much to get the flavour causes diarrhoea.
