DOES CHEWING GUM CLEAN TEETH?

Chewing gum has long been used as a convenient way to freshen breath, but does it actually clean your teeth?

In recent years, many brands have marketed sugar-free gum as a tool for improving oral health. With claims that it can help prevent cavities and clean teeth, it’s natural to wonder: can chewing gum actually contribute to a healthier mouth?

While gum alone is no replacement for daily brushing and flossing, certain types of sugar-free gum can offer benefits that support overall oral hygiene.

The key lies in how chewing gum interacts with saliva production and the types of ingredients it contains.

Chewing gum increases saliva production

Sugar-free chewing gum stimulates saliva production, which plays a vital role in maintaining oral health.

Saliva acts as the mouth’s natural defence mechanism, helping to wash away food particles, neutralise acids that contribute to tooth decay, and deliver essential minerals such as calcium and phosphate to strengthen tooth enamel.

Increased saliva flow also helps combat dry mouth, a condition that can lead to a higher risk of cavities and bad breath.

How xylitol in chewing gum can help teeth

Many sugar-free gums also contain xylitol, a natural sweetener that has been shown to inhibit the growth of cavity-causing bacteria.

Unlike sugar, which feeds bacteria and promotes plaque formation, xylitol disrupts bacterial metabolism, reducing their ability to stick to the teeth and cause decay.

Regular use of xylitol-containing gum, in conjunction with good oral hygiene practices, may contribute to improved oral health.

The limitations of chewing gum

While chewing gum can offer benefits, it does not replace proper brushing and flossing. It cannot remove plaque buildup, clean between teeth, or eliminate bacteria from below the gumline.

Relying on gum alone for oral hygiene would leave teeth vulnerable to decay and gum disease over time.

Additionally, not all chewing gum is beneficial. Gum containing sugar can actually increase the risk of cavities by providing a food source for harmful bacteria.

Jaw pain and chewing gum

It’s important to note that excessive gum chewing may not be suitable for everyone.

Those who suffer from temporomandibular joint disorder (TMD) or jaw pain may find that frequent chewing exacerbates discomfort.

If you experience jaw pain, it may be best to limit or avoid gum chewing altogether.

The best way to keep your teeth clean and healthy

For optimal oral health, chewing sugar-free gum can be used as a supplementary measure, particularly after meals when brushing may not be immediately possible.

However, it should always be combined with a thorough oral care routine that includes twice-daily brushing with fluoride toothpaste, flossing, and regular dental check-ups.
