Mouthwash

Colgate Fluorigard Daily Rinse (alcohol free)

By Colgate

A fluoride rinse focused on preventing decay rather than freshening breath. Used at a separate time from brushing – after lunch, say – it adds an extra fluoride top-up, as the NHS suggests.

Can be useful for

A product can support daily care but can’t treat a dental problem on its own. See a dentist if symptoms persist.

Choosing mouthwash

  • Choose a fluoride mouthwash if your goal is decay prevention.
  • Use mouthwash at a different time from brushing.
  • Treat chlorhexidine rinses as short-term medicines and read the leaflet.
  • Check age limits on the label – some are not suitable for young children.
  • Mouthwash does not replace brushing or cleaning between teeth; see a dentist about persistent bad breath or bleeding gums.
