gently brush your teeth and gums at least twice a day for 2 minutes
use a fluoride toothpaste
gently clean your tongue once a day using a tongue scraper or cleaner
clean between your teeth with interdental brushes or floss at least once a day
get regular dental check-ups
keep dentures clean and remove them at night
use sugar-free mints or chewing gum after having strong-smelling food and drinks
try using an antibacterial mouthwash or toothpaste
do not rinse your mouth with water straight after brushing your teeth
