How can you avoid tartar build-up?

May or may not: Tartar accumulation is best minimized by careful oral hygiene. Brushing at least twice a day for two minutes and flossing at least once per day, preferably in the evening, helps to remove food and plaque from the teeth. In turn, if the teeth don't have any plaque on them, it is less likely that tartar will form from the calcification of the remaining plaque on the teeth.

Brushing & flossing: Best way to avoid tarter build-up is to have your teeth professionally cleaned and follow the dentist's tooth brush and flossing instructions. Tarter starts to build up in areas you miss when you are brushing and flossing. You can avoid it by making sure you brush and floss all the surfaces of each tooth. A dentist can help you determine what areas you are missing.
