Suppression of cariogenic microorganisms can be achieved by dietary modification, by limiting the intake of fermentable carbohydrate (cariogenic foods); by avoiding or limiting the intake of acidic foods and drinks; by limiting snacks between meals; and by chewing sugar-free gum. The bioburden of harmful bacteria can further be reduced by the addition of beneficial bacteria to the oral flora.41 Probiotics (Figure 5) available in oral formulations, typically as a lozenge, appear to be useful in the control of cariogenic and periopathogenic bacteria.43
