Like most things in this world, the matter of gum chewing is not one that is black and white. While some may consider it to be an unattractive and even damage-causing habit, research studies have demonstrated that there are indeed benefits to chewing gum.
The Cons…
- Sugar: Chewing gum sweetened with sugars like high-fructose corn syrup are unquestionably bad for your dental and general health, leading to tooth decay and weight gain.
- Artificial sweeteners: Some of the gums on the market that are sweetened without sugar usually contain Aspartame or
- Sucralose: which can have side effects like diarrhea if consumed in larger quantities and have been associated with health risks including cancer and neurological problems.
- Stomach problems: The act of chewing gum causes one to swallow quite a bit of air which can cause stomach upset and discomfort.
- Stress and additional wear and tear on jaw muscles: The repeated act of chewing can put additional strain on your jaw muscles and cartilage, causing premature deterioration and chronic headaches.
- Appetite stimulant: Chewing stimulates the body to produce digestive juices and can increase one’s desire to eat which for many of us, is not a good thing.
The Pros…
- Cavity reduction: A study published in the Summer of 2012 in the Journal, Caries Research, associated frequent gum chewing with higher salivary flow rates and reduced severity of cavities. A common ingredient in sugarless gum is Xylitol, a sweetener that actually helps prevent cavities by reducing the growth of bacteria that causes tooth decay.
- Helps relieve sensitivity associated with whitening: Another recent study published in British Dental Journal found that chewing sugar-free gum after in-office whitening could reduce the intensity of tooth sensitivity.
- Increased mental performance. Teachers have anecdotally reported that students who chew gum require fewer breaks, pay more attention and stay quieter than those who do not.
- Helps lose weight: Here’s a tough one to wrap your head around… Contradictory to what I just reported, other research studies have demonstrated that chewing gum can be an effective tool in losing weight. According to the Mayo Clinic, the body burns 11 calories an hour working the jaw. Some people report that chewing gum can satisfy food cravings without having to eat.
- Helps alleviate stomach problems: In another contradiction, it has been observed that individuals who suffer from acid reflux disease find relief in chewing gum, as the increased saliva flow can lead to an antacid effect in the stomach.
- Relieves Dry Mouth: Chewing gum has been shown by research to stimulate the flow rate of saliva by a factor of ten. This is essential for patients suffering from Dry Mouth or Xerostomia.
In Summary…
As I mentioned earlier, there are no clearcut answers here. Generally speaking, I would suggest an approach that relies on the old adage, “everything in moderation.” Everyone is different and I would advise that the best approach for one would not be for another. As health professionals, it is the role of your dentist and your physician to assess what the best solution is for each individual patient.
