Chewing gum in various forms has been around since ancient times. The Greeks chewed sap from the mastic tree, called mastiche. On the other side of the world, the ancient Mayans favored the sap of the sapodilla tree (called tsiclte). Native Americans from New England chewed spruce sap—a habit they passed on to European settlers. Today, the base used for most gum products is a blend of synthetic materials (elastomeres, resins and waxes in various proportions). However, chewing gum is as popular as ever. Consumers may be used to thinking about chewing gum as a kind of candy, but this category of the ADA Seal recognizes chewing gum that has demonstrated scientifically that it can protect the teeth.
Gum Chewing & Oral Health
The physical act of chewing increases the flow of saliva in your mouth. If you chew after eating, the increased salivary flow can help neutralize and wash away the acids that are produced when food is broken down by the bacteria in plaque on your teeth. Over time, acid can break down tooth enamel, creating the conditions for decay. Increased saliva flow also carries with it more calcium and phosphate to help strengthen tooth enamel. Clinical studies have shown that chewing sugarless gum for 20 minutes following meals can help prevent tooth decay.
