Chewing gum. Good? Bad? Both? Read more

A quick survey of any store’s candy shelves will tell you that there are a lot of chewing gum options out there. And not all chewing gums are created equal. But can chewing gum be good for you? If so, what kind of gum might be the healthiest to chew? Different experts see it different ways. In this article, we’ll cover some of the pros and cons of chewing gum as it connects to your dental health.

When chewing gum isn't helpful

There are some cases where chewing gum can lead to problems. A few tips:

  • Avoid chewing a lot of gum that’s made with sugar. Dental experts agree that chewing gum with sugar is a poor choice. In fact, the sugar in the gum can actually increase your chances of getting a cavity.1
  • Chewing gum is a no-no for people who have jaw pain, or who have symptoms of “TMD” or “TMJ” – “Temporomandibular Disorder.” This is basically a problem of the joint in the jaw. Chewing gum can make TMJ worse. 2
  • Skip chewing gum with artificial sweeteners like aspartame, which has been linked to cancer.3 Read the label on your chewing gum package and “eschew” gum with aspartame.
  • Dental work like crowns, bridges, and fillings might be loosened, or even broken by sticky gum.

The good news

But chewing gum has its good points, too.

For one thing, chewing makes our mouths produce more saliva. Saliva is our “natural mouthwash” that helps keep our teeth clean. It not only “rinses” food particles out of our mouths, but also reduces acids that can be hard on tooth enamel. In times or places where you can’t brush or floss your teeth, a piece of chewing gum might be better than nothing.4

Sugar-free gum is the chew to choose

Another area where dental experts agree: sugar-free gum is the best choice by far. But some sugar-free gums are better than others. It all depends on what’s in them.

Some studies show that sugar-free gum with a sweetener called Xylitol can actually help fight tooth decay. Xylitol has been shown to slow the growth of bacteria called Streptococcus mutans. This bacterium is a cause of cavities, and Xylitol keeps it from sticking to tooth enamel. Over time, it seems Xylitol can even help discourage Streptococcus mutans and other mouth bacteria from forming in the first place.5

There’s also some new research into a sugarless gum ingredient called calcium lactate. When it’s used in chewing gum that also has Xylitol, it seems that calcium lactate can boost “helpful” minerals in tooth enamel.8

Other sugar-free gum sweeteners approved by the American Dental Association (ADA) include sorbitol, mannitol, and aspartame.6 But as we mentioned earlier, many experts believe there’s a link between aspartame and cancer.

No matter which kind of gum you choose to chew, it’s important to note that the only kinds of gum that the ADA approves are sugarless.7

Read the label

As with any other food, it pays to read the label on that pack of gum before you buy it. All experts say the most important thing is that it’s sugar-free. From there, you can look for the kind of sweetener the gum uses. Sugar-free gum with Xylitol and calcium lactate seems to be the best option today.

Not a replacement for brushing and flossing

As you choose your sugar-free chew, please keep one more thing in mind. The ADA, and all dental groups we reviewed, is very clear that brushing and flossing are the number-one things you can do for your mouth’s health. Chewing sugar-free gum may help, but doesn’t come close to daily brushing and flossing.

That said, you can go ahead and enjoy that piece of sugar-free gum, guilt-free, especially at times when you can’t brush or floss. Chews – er, cheers – to a happy, healthy smile!
