Chewing sugarfree gum for 20 minutes after meals and snacks can help patients to neutralize plaque acid. The saliva stimulated by chewing gum can help reverse the fall of pH caused by plaque bacteria following the consumption of sugars and starches. This reversal is due to the increased buffering effect of higher levels of bicarbonate found in stimulated saliva. Stimulated saliva's buffering effect also can help to reduce erosion of tooth enamel.
