When you were a young child, your parents probably told you a few (hundred) times that candies and sweets would "rot your teeth." Yes, that's mostly true, but there are a few exceptions. Cavities only occur when you have the right "Cavity Combination" in your mouth.

Your Parents Were Right - Mostly

For cavities to start, you need to have a food source. This food source is sugar! This can be complex sugars, but simple sugars can accelerate cavity formation. Next you need something to eat the sugar and produce acid to dissolve the minerals out of your teeth. This is were your friendly streptococcus mutans become the star of the show. This bacteria break down the sugars and produce a waste product of lactic acid. This lactic acid is what "eats" away the tooth structure.

So I like to tell children that when they're too lazy to brush their teeth, the tooth bugs eat any candy left that didn't get brushed away and poop out acid that dissolves their teeth. You can only imagine the funny faces these children make when they hear my bug pooping story.The good news is that chewing a stick of gum may do the opposite. It does not only make your breath fresher after meals, it also has a lot of other benefits in preventive dentistry.

How Does Chewing Gum Help?

Chewing gums made today contain the same main ingredients. These ingredients include a gum base, sweeteners (primarily sugar and corn syrup), and some flavorings such as spearmint, peppermint and cinnamon. Some gums contain softeners like glycerin and vegetable oil. Because of the advancements in food science, several different types of gums have been made available today with additional ingredients that can benefit the oral health. Popular examples of these chewing gums include sugarless gums and gums containing xylitol, which is part of a good preventive dentistry plan.

You've probably read or heard that chewing gum can increase the flow of your saliva. That's correct. But, how does chewing gum after a meal help your oral health? Since chewing a gum increases saliva production, the increased flow of saliva helps in flushing out food debris, remaining sugars, and harmful acids in your mouth that were produced while you were eating your food. If not washed away, these debris, sugars, and acids can break down the outer surface of your teeth and form tooth decay overtime. Also, an increase in salivary flow carries with it more calcium and phosphate which are essential in strengthening the outer surface of our teeth. Studies have shown that chewing a sugar-free gum after a meal for 20 minutes can help in preventing formation of tooth decay. Can you see how this is a great part of preventive dentistry?

Why Not Concentrate on Prevention Tactics

I have noticed an increase in cavities in teenagers in the Lewiston and Auburn Maine area due to a lack of preventive dentistry. Most people seem to be very interested in teeth whitening and cosmetic dentistry, but if you do not have a good foundation of posterior teeth, your front teeth will fracture. Why not concentrate on preventing tooth decay, especially when it's as easy, and fun, as chewing a stick of gum.

And did you know that chewing gum can also improve your digestion? As we all get older, our body produces less and less stomach acid. Because of this, some of us can have a hard time digesting some foods. Chewing gum which is made from xylitol, a natural sweetener, contains the best digestive benefits. In order to improve your digestion, try chewing a gum which contains xylitol before eating or right after eating. More saliva may help you build up the amount of acid in your stomach that is needed by your body in order to digest your meal.

So make sure you choose a sugar free gum (look for an ADA seal), be sure it contains xylitol if you're chewing for the additional digestion benefits, and make preventive dentistry (and preventive health) a habit.

Note - Chewing gum doesn't replace brushing and flossing! And if you think chewing gum before or after meals doesn't help with digestion, consult your doctor to make sure you don't have a more serious problem regarding your digestive system. If you struggle digesting aver every meal, it could be a sign of something more serious.
