Chewing gum's health impact depends heavily on its ingredients and frequency of use. While it offers some oral health benefits, excessive chewing can lead to problems.
Oral Health Benefits of Chewing Gum
- Increased Saliva Production: Sugar-free gum stimulates saliva production. This is crucial because saliva neutralizes acids produced by plaque, strengthening teeth and reducing tooth decay. [American Dental Association, Multiple Sources].
- Plaque Acid Reduction: The increased saliva flow helps wash away food particles and harmful sugars, further reducing plaque acid and improving oral health. [Mulgrave Dental Group, American Dental Association].
- Protection Between Meals: Chewing sugar-free gum between meals provides a protective effect when brushing isn't immediately possible. [Oral Health Foundation].
Potential Drawbacks of Chewing Gum
- Jaw Problems: Excessive gum chewing can strain the jaw muscles, potentially leading to temporomandibular joint (TMJ) disorders. [Cleveland Clinic, Rejuvenation Health].
- Dental Issues: While generally beneficial, excessive or forceful chewing can damage teeth or fillings. [Cleveland Clinic].
- Sugar Content: Sugar-containing gums contribute to tooth decay, negating the positive effects of increased saliva. Always choose sugar-free options. [WebMD].
Mental Health Aspects
Some studies suggest that chewing gum may offer minor cognitive benefits and stress relief, but more research is needed to solidify these findings. [Colgate, PubMed]. The effects on mood or fatigue are still unclear. [NCBI PMC].
Conclusion
Chewing sugar-free gum in moderation can be beneficial for oral health due to its effect on saliva production and plaque reduction. However, excessive chewing may lead to jaw and dental problems. The impact on mental health requires further investigation.
