Aspartame doesn’t trigger dental decay as regular sugar does, pointed out Fatima Khan, a dentist and co-founder of Riven Oral Treatment in Houston, Texas

“Standard sugar is fermentable and functions as a food resource for cavity-triggering microorganisms,” she instructed Fox News Digital. 

“Having said that, synthetic sugars like aspartame are not fermentable, and as a result cavity-leading to bacteria can not use them as a food supply.”

Whilst aspartame itself will not right hurt the teeth, some dentists alert that other ingredients in the gum could cause tooth decay.

Sugar-no cost chewing gum has substances these types of as carbonic acid, phosphoric acid, malic acid, citric acid, tartaric acid and fumaric acid, all of which are discovered in a variety of eating plan sodas, Khan reported.


“All of these acids lessen the pH in your mouth,” she reported. “When your mouth’s pH falls underneath 5.5, your enamel demineralizes, the calcium and phosphate in your enamel weakens and breaks down, and your enamel erode.”

Tooth enamel allows to guard the enamel from dental decay, Khan claimed.

“The layer beneath, recognised as dentin, is much less mineralized and a lot more vulnerable to decay due to its softer nature,” she extra.

“Sugar and acid are two of the greatest culprits when it will come to tooth decay,” Dr. Sean Kutlay, a normal dentist in Santa Clarita, California, verified to Fox Information Electronic. 

“Any sugar-free of charge gum is wonderful, as it stimulates extra saliva, which allows to reduce the acidity of the mouth and avert cavities, particularly following a meal.”

Although aspartame was a short while ago considered a doable carcinogen, Kutlay claimed the ordinary individual would need to have to ingest about 450 sticks of sugar-free of charge gum to surpass the daily prompt restrict.


“A adhere of gum following just about every food chewed for 10 to 15 minutes will supply so significantly gain for your oral wellbeing,” he stated.

Aspartame-containing gum can also result in prospective digestive health and fitness issues, which can indirectly influence oral health and fitness, according to Dr. Nicole Mackie, a dentist at the Dental Implant Specialty Center in Las Vegas, Nevada.

Whilst aspartame doesn’t trigger tooth decay or cavities, dentists advocate opting for xylitol, a naturally developing sweetener found in vegetation, as a extra beneficial sugar-absolutely free alternative.

“The motive xylitol is advised is for the reason that cavity-creating microbes are not able to metabolize this sugar and use it as gas, and it starves the cavity-leading to bacteria and can help prevent tooth decay,” Khan claimed. 

“It decreases cavity-producing bacteria, increases saliva creation and aids remineralize enamel.”
