15 Benefits Of Chewing Gum


Gum is chewed for a variety of purposes. For instance, it is believed that chewing gum may increase saliva production, clean teeth, aid digestion, reduce stress, and elevate mood.

Gum may not be a miraculous cure, but there are some intriguing advantages to chewing it.

Let’s explore these distinct but remarkable benefits of chewing gum.

Benefits Of Chewing Gum

Chewing gum that is sugar-free is an interesting tactic to munch without adding extra calories. The following are a few of the benefits of chewing gum-

  1. Improves Oral Health And Prevents Cavities

    Gum is healthy for your teeth, which is perhaps the only aspect of chewing gum that most people are aware of.

    Particularly sugar-free gum is recognized for its ability to prevent tooth decay; its benefits are comparable[1] to those of fluoridated mouthwash and toothpaste.

    After a meal, chewing on sugarless gum for just 20 minutes helps prevent gingivitis and tooth decay.

    In essence, it prevents[2] tooth decay by boosting saliva production in the mouth and clearing acids and food residue from the teeth.

    Saliva provides[3] the enamel with calcium and phosphate to strengthen it, which further aids in maintaining its strength.

    This indicates that the teeth are more resistant[4] to cavities and decay.

  2. Enhanced Digestion

    Some people believe the ancient folktales about swallowing gum, which is why chewing gum occasionally gets a bad rap.

    The good news is that there are several great digestive health benefits of chewing gum. Gum generally doesn’t block your intestines or stay in your system for a very long time.

    Although chewing gum doesn’t directly affect digestion, doing so before a meal helps with digestion.

    This occurs because chewing stimulates the production of saliva and digestive[5] acids in the mouth and stomach, effectively preparing the body for a meal.

    Therefore, keeping the stomach ready, not only makes swallowing food easier but also enhances digestion.

    Gum chewing helps to further stimulate the digestive process, which not only keeps the mouth healthy but also helps prevent indigestion.

  3. Reduce Acid Buildup

    Do you often have heartburn? After meals, chew a stick of gum to reduce the amount of acid that builds up in your esophagus and reduce heartburn and acid reflux symptoms[6].

    Saliva is produced more frequently when you chew gum, and it becomes more alkaline so that it can counteract the acid. It may also prevent[7] acid reflux after meals.

  4. Control Your Appetite

    Chewing gum can aid with appetite control and promote healthier eating habits. Additionally, chewing gum helps you burn a few additional calories.

    Moreover, sugar-free chewing gums could help in reducing[8] appetite when taken between meals as it could develop the feeling of fullness making you eat lesser.

  5. Eliminates Ear Blocks

    Many people find flying to be uncomfortable because the pressurized cabin might irritate and hurt their ears or obstruct their ears.

    A pack of gum is a fantastic approach to alleviate discomfort.

    Chewing a stick of gum will naturally aid in the air pressure in the ear equalizing with the outside pressure rather than squeezing your nose and attempting to blow your ears clear.

    After a shower or swim, it is also a helpful cure to remove any water that becomes clogged in the ears.

    The motion of chewing forces the liquids out of the ear and helps to empty the sinus cavities.

  6. Freshens Breath And Prevents Dry Mouth

    Lack of salivary flow and the resulting growth of too many germs are two factors that contribute to bad breath.

    Gum chewing increases saliva production, kills harmful bacteria, and keeps your mouth fresh all day. It may also prevent[9] the problem of dry mouth.

    All you need to keep your mouth feeling fresh throughout the day is a piece of sugar-free gum with a mint flavor.

  7. Cleaning Up Meal Leftovers

    Gum chewing can encourage the elimination[10] of food residue that remains after eating.

    Increased mastication and salivation help to wash away debris, although removal is also partially caused by the direct attachment of debris to the gum.

    Removing debris as soon as possible after food ingestion is important.

    It may be because it frequently contains fermentable carbohydrates, which bacteria use to make acids that absorb calcium and phosphate from the enamel minutes after consumption.

  8. Remineralization Of Enamel

    Saliva’s high calcium and phosphate content may help[11] to remineralize enamel and stop it from demineralizing.

    Regular sugar-free gum chewing increases saliva production, which raises calcium and phosphate levels in the oral cavity.

    Regular sugar-free gum chewing several times a day, together with good oral hygiene practices, can reduce the prevalence of caries, especially after meals.

  9. Accelerates Memory

    Although chewing gum has been linked to reducing tension and anxiety, it may also help in improving memory and increases blood flow to the brain.

    Gum chewing may boost short-term memory and increase blood flow to the brain.

    Cognitive function and overall test performance are greatly improved when munching on the gum.

    The observed rise in heart rate and blood flow is ultimately thought to be the source of this beneficial mental boost.

    The scientific findings[12] unquestionably supported this:

    The hippocampus, a region crucial for focus and reaction times, had a considerable rise in brain activity, and oxygen flow to the brain was boosted by up to 40%.

    Exam performance may be enhanced by chewing gum while studying, maybe due to the effects of gum on attentiveness.

  10. Assists With Weight Loss

    If you’re suffering from lunchtime cravings, choosing some gum instead of that bag of chips may help you stick to your weight-loss plan.

    Not only does this reduce your calorie intake, but over time the gum will start to function as a “signal” that you are no longer hungry.

    This successfully suppresses[8] your appetite and encourages you to eat less.

    The people who choose a stick of gum instead of a snack in between meals will reap the most benefits.

    It has been shown that mindless nibbling aids in appetite suppression.

  11. Reduces Nausea

    Are you prone to motion or morning sickness? Your holy grail may very well be herbal gums.

    The ginger components and increased salivation help[13] with digestion and irritation of the stomach.

    Leading anti-nausea medications may not be as helpful as chewing a piece of gum.

    After major colon surgery, colorectal surgeons routinely advise patients to chew gum to assist stimulate their digestive systems.

  12. Improves Alertness And Reduces Anxiety

    You might want to think about chewing on a stick of gum if you have an upcoming task that demands laser focus.

    Gum chewing is regarded as one of the most effective ways to raise alterity and attentiveness.

    This might be because chewing causes the blood flow to the brain to rise.

    Gum may be able to aid you if you frequently experience tension and anxiety.

    According to this study[14], chewing gum lowers stress and anxiety levels but it shouldn’t be consumed in the long term for students.

  13. Gain Mental Strength

    Would you believe that chewing gum also improves your brainpower? Many people find it to be true.

    Gum chewing has a variety of negative effects on mental health. Get mentally involved.

    When you’re feeling drowsy in the afternoon, do you rush to get a cup of coffee or tea? Grab a stick of gum instead, maybe.

    Chewing gum not only makes you more alert but also facilitates[15] cognitive function by promoting blood flow to the brain.

    Due to increased blood flow and oxygen to the brain, chewing gum also enhances memory and cognitive function.

  14. The De-Stressor

    The advantages of long-term stress reduction chewing suggest[16] that it can be a straightforward, affordable approach to lowering stress and enhancing the quality of life and well-being.

    Chewing gum can be the easy solution you’re looking for if you have trouble staying focused at work.

    The prefrontal cortex is involved in the neural processes that underlie the stress-relieving effects of chewing gum.

    These processes alter the activity of the autonomic nervous system and the hypothalamic-pituitary-adrenal axis.

    The rostral medial prefrontal cortex’s increased glucose metabolism has been linked[17] to a decrease in salivary cortisol, which implies that feeding the appropriate brain regions with glucose may lessen stress.

    Gum chewing may have an impact on stress through its effects on neurotransmission.

  15. Accountability For Health

    While it has been discovered that supermarket shopping helps you put less junk in your cart.

    It may be simpler to maintain a nutritious diet throughout the week as a result. Additionally, chewing gum will prevent you from consuming pointless calories as you prepare dinner.

Final Thoughts

Thus, Gum chewing has been shown to increase alertness, lessen anxiety, and lower stress and salivary cortisol levels.

When you need a little aid with memory improvement, stress reduction, or adhering to your diet, try chewing gum.

Though it should be kept in mind that chewing gum comes with benefits when taken in moderation and when consumed in excess, it could pose problems in the long run.
