What Makes a Gum Healthy?
Choosing a healthy gum goes far beyond simply picking a sugar-free label. While sugar is the most obvious ingredient to avoid due to its link to tooth decay, a truly healthy gum should contain beneficial ingredients and steer clear of controversial artificial additives. The key is to understand what's in the gum base, what's used for sweetening, and what other substances are included.
The Importance of Sweeteners: Xylitol vs. Aspartame
The choice of sweetener is the most critical factor in determining if a gum is healthy. Sugar-alcohols and natural sweeteners provide flavor without feeding the harmful bacteria that cause cavities, unlike regular sugar.
- Xylitol: This naturally occurring sugar alcohol, found in many fruits and vegetables, is a standout ingredient. It has been shown to reduce levels of Streptococcus mutans, the bacteria responsible for tooth decay, by up to 75% in some studies. Bacteria cannot metabolize xylitol, which starves them and helps maintain a healthy oral environment.
- Stevia: Derived from the stevia plant, steviol glycosides are a calorie-free, natural sweetener. Studies show it does not negatively affect oral health and can be a good alternative to aspartame. Some users report a slight bitter aftertaste, but many modern formulations have minimized this.
- Aspartame and Sucralose: These are common artificial sweeteners that are FDA-approved but have faced some controversy. While they do not cause cavities, some individuals report side effects like headaches or digestive issues from excessive intake. Gums made with natural alternatives like xylitol or stevia are often preferred for those seeking a 'cleaner' product.
The Gum Base: Natural vs. Synthetic
Many conventional gums are made with synthetic polymers, essentially plastics and waxes derived from petroleum. A healthier, and more eco-friendly, alternative is a natural gum base.
- Natural Chicle: Traditionally harvested from the sapodilla tree, chicle is a biodegradable and plant-based gum base. Brands like Simply Gum and Chicza use chicle, offering a cleaner and more sustainable chew.
- Other Natural Bases: Ingredients like gum arabic (from acacia trees) and mastic gum (from the mastic tree in Greece) also provide a natural, plant-based alternative to synthetic gum bases.
Benefits of Chewing a Healthy Gum
Beyond just oral hygiene, chewing the right gum can offer several health benefits:
- Boosts Oral Health: Chewing stimulates saliva production, which helps neutralize mouth acids, wash away food particles, and provide calcium and phosphate to remineralize tooth enamel. Sugar-free gum, especially with xylitol, is recommended by dentists for these benefits.
- Aids Digestion: The act of chewing triggers the digestive system to produce saliva and enzymes, which can help alleviate symptoms of indigestion or heartburn, especially after a meal.
- Freshens Breath: The stimulation of saliva flow and the presence of bacteria-fighting ingredients like xylitol help combat the root causes of bad breath.
- Reduces Stress and Improves Focus: The repetitive chewing motion has been linked to reduced cortisol levels and increased blood flow to the brain, potentially improving memory, alertness, and reducing stress.
Potential Risks and Side Effects
Even with healthy gum, moderation is key. Excessive chewing can lead to problems:
- Jaw Strain: Constant chewing can put a strain on the temporomandibular joint (TMJ), potentially leading to pain or disorder.
- Digestive Issues: Overconsumption of sugar alcohols like xylitol or sorbitol can have a laxative effect and cause bloating, gas, or diarrhea in some individuals, particularly those with IBS.
- Dental Work: People with fillings, crowns, or braces should be cautious, as sticky gum can sometimes dislodge dental work.
Comparison of Healthy Gum Options
| Feature | Natural Chewing Gum (e.g., Simply Gum) | Xylitol-Based Gum (e.g., PUR Gum) | Standard Sugar-Free Gum (e.g., Trident) |
|---|---|---|---|
| Gum Base | Natural chicle, biodegradable | Synthetic polymers | Synthetic polymers |
| Sweeteners | Xylitol, stevia | 100% Xylitol | Aspartame, sorbitol |
| Additives | Minimal, often uses natural flavorings | Generally free of artificial colors/flavors | May contain artificial colors and flavors |
| Oral Health Benefit | Stimulates saliva, some brands with xylitol fight bacteria | Reduces cavity-causing bacteria effectively | Stimulates saliva, but no specific antibacterial effect from sweetener |
| Digestive Impact | Lower risk of digestive issues, especially with stevia | Potential for laxative effects if consumed in large amounts | Potential for digestive issues from sorbitol |
| Taste Duration | Often shorter-lasting flavor than conventional gum | Can offer long-lasting flavor | Designed for long-lasting flavor |
What to Look for When Choosing a Healthy Gum
When standing in the gum aisle, a few simple checks can guide you toward the healthiest option:
- Check for Xylitol: Prioritize gums listing xylitol as the primary sweetener. This is the most beneficial ingredient for fighting oral bacteria and preventing cavities.
- Look for Natural Ingredients: If possible, choose brands that use a natural gum base like chicle over synthetic polymers for a more eco-friendly and potentially cleaner product.
- Find the ADA Seal: For an extra layer of confidence, look for the ADA Seal of Acceptance, which indicates the gum has been tested and proven to be safe and effective in improving oral health.
- Read the Label: Be aware of artificial additives like colors and flavorings. Many natural brands avoid these, providing a purer chewing experience.
Conclusion
Is there a healthy gum to chew? The answer is a clear yes, but with the caveat that not all gums are created equal. By opting for sugar-free gums with a natural sweetener like xylitol and a plant-based gum base, you can enjoy the oral health benefits of increased saliva flow and bacteria reduction while avoiding controversial artificial ingredients and synthetic materials. Chewing gum in moderation can be a great supplement to your oral hygiene routine, but it should never be considered a replacement for regular brushing and flossing. Being an informed consumer allows you to enjoy a satisfying, healthy chew that benefits your teeth and overall wellness.
