Sugar-free chewing gum protects against tooth decay

Reduced risk of caries through sugar-free chewing gum

Chewing sugar-free chewing gum appears to reduce the development of tooth decay in the teeth of adults and children, according to a recent study.

The recent investigation by King’s College London found that sugar-free chewing gum can help us keep our teeth healthy. The results of the study were published in the English-language journal "Journal of Dental Research: Clinical & Translational Research".

Sugar-free chewing gum reduces the progress of tooth decay

The investigation found evidence that chewing sugar-free gum reduces the progress of tooth decay. This finding could potentially be used in the future as a viable preventive measure against tooth decay.

Data from twelve studies on sugar-free chewing gum were evaluated

For the current study, the results of various studies that have been published over the past 50 years have been analyzed. In this way, twelve studies were identified that deal with the effects of sugar-free chewing gum on oral health. Dental caries in adults and children in particular were the focus of the studies.

Chewing gum has a 28 percent preventive factor for tooth decay

The researchers found that sugar-free chewing gum reduces the increase in tooth decay. In addition, people who regularly chew sugarless chewing gum had 28 percent less tooth decay. The team recommends chewing sugarless gum more often to protect our teeth from tooth decay.

Were there any restrictions in the study?

Unfortunately, many of the studies evaluated were generally of poor quality. The researchers still felt that there is an urgent need to update existing knowledge about sugar-free chewing gum and its effects on tooth decay and oral health.

Further studies on the subject are planned

"We are planning further studies to determine the acceptance and feasibility of using this method in healthcare," said Professor Avijit Banerjee of King’s College London in a press release. In recent years, sugar-free chewing gum has emerged as a possible addition to existing prevention strategies to prevent tooth decay. The acceptance and feasibility of using this method in healthcare should now be determined.

Why does sugar-free chewing gum protect us from tooth decay?

The stimulation of human saliva could protect against tooth decay because the saliva present in the mouth can serve as a natural barrier to protect the teeth. On the other hand, chewing gum triggers a kind of mechanical plaque control, which in turn helps prevent tooth decay. It is also possible that sugar-free chewing gum contains antibacterial ingredients such as xylitol and sorbitol, which can protect the health of our teeth.

Evidence suggests protective effects

Before evaluating the various studies, there was no conclusive evidence to show the relationship between slowing caries development and chewing sugar-free gum. However, the current investigation provided such evidence and shows that sugar-free chewing gum can actually protect against the development of tooth decay. (as)
