The major enemy of oral health is plaque. Food that becomes trapped near tooth surfaces can lead to the formation of plaque — a thin coating of microorganisms and organic debris (biofilm) containing potentially harmful bacteria. Keeping plaque under control is one of the most effective means of maintaining strong, healthy teeth and gums. There are three general ways to do it: through diet, daily maintenance, and regular dental and orthodontic appointments. Taken all together, they’re your teeth’s best defense.
