The chewing effect itself can be beneficial, in that chewing any gum stimulates salivary flow which buffers the effects of plaque. There are products available now that incorporate xylitol, a natural sugar. They prevent acid production by bacteria and make it more difficult for bacteria to stick to teeth. Since the pH doesn’t drop with xylitol-sweetened products like it will with other sugars, enamel breakdown is prevented. For patients who chew gum regularly, these products can now offer a supplement to benefit your oral hygiene routines.
