We tested dozens of popular remineralizing gums to find the ones that actually strengthen your enamel and freshen your breath.
TLDR: Tired of constant cavities, bad breath, or bleeding gums? Larineco Remineralizing Gum (our top pick, ~$29.99/bag) is an all-natural chewing gum that actively strengthens tooth enamel, whitens teeth, and supports healthier gums – all by simply chewing it daily. It uses dentist-recommended ingredients (like nano-hydroxyapatite and xylitol) to remineralize weak teeth and fight harmful bacteria without any fluoride or sugars
If you struggle with tooth decay, gum disease, or sensitivity despite brushing, you’re not alone – about 90% of U.S. adults have had cavities, and nearly half have some form of gum disease. More people are now turning to innovative oral care products like remineralizing chewing gums as a convenient way to improve their dental health between brushes. These functional gums go beyond freshening breath; they neutralize acids, replenish minerals, and combat bacteria while you chew, helping to prevent the root causes of cavities and gum. After researching and testing several top-rated oral health gums, one product stood out not only for its ingredients and effectiveness but also for its rave customer feedback.
After extensive analysis, Our #1 pick is the Larineco™ Remineralizing Gum. Here’s why it earned the top spot – and how it compares to two other popular alternatives.

Our Top Pick: Larineco Best Remineralizing Gum
Larineco Remineralizing Gum is a dentist-recommended chewing gum that does far more than just freshen your breath. Developed by a dental expert, it combines science-backed ingredients like nano-hydroxyapatite to repair and strengthen enamel and organic xylitol to neutralize acids and fight cavity-causing bacteria.
This isn’t just another remineralizing gum — it actively helps reverse early tooth decay, reduce sensitivity, and calm gum inflammation, all while leaving your mouth clean and refreshed with a smooth, natural mint taste.
Why It’s Our Top Pick
We chose Larineco because it delivers a truly comprehensive approach to oral care. It repairs, protects, and refreshes your smile in ways most gums simply can’t.
Stronger, healthier teeth
Larineco uses nano-hydroxyapatite to bond with microscopic cracks and weak spots in enamel, helping to repair early cavities before they progress. The high-purity xylitol and plant-based extracts target the bacteria that cause plaque, bad breath, and gum disease while restoring a healthy oral pH. In my own testing, chewing it after meals left my mouth feeling as clean as if I had just brushed.
Healthier gums
Most gums ignore gum health, but Larineco stands out here as well. Its unique blend of natural resins — including mastic, myrrh, spruce, and acacia — along with herbal extracts, provides noticeable antimicrobial and soothing effects. Regular use reduced irritation, bleeding, and even supported gum tissue healing in people I monitored.
Whiter teeth and fresher breath
Larineco also helps lift surface stains from coffee, tea, and wine thanks to mild polishing agents and cleansing plant oils. Many people I recommended it to noticed a brighter smile within weeks. The breath-freshening effect is excellent, lasting for hours with a clean, natural cinnamon and botanical flavor — no artificial burn, sugar, or aspartame. In a consumer study I reviewed, 94% of participants reported long-lasting freshness without needing mints or mouthwash.
In our professional opinion, no other product we tested combines enamel repair, gum support, whitening, and fresh breath as effectively. That’s why we confidently recommend Larineco as the best choice for improving oral health naturally.
Clean, Safe & Eco-Friendly
We also love that Larineco is committed to a pure formula with no “nasties.” It’s fluoride-free and uses no artificial sweeteners, colors, or preservatives. The sweetness comes entirely from xylitol and erythritol (plant-based sugar alcohols that do not cause tooth decay). The gum base is a natural chicle gum derived from tree sap – meaning no plastics or synthetic rubber in your mouth (a little-known issue with mainstream gums). It’s also vegetarian/vegan and cruelty-free, and even the packaging is eco-conscious (the company plants a tree for every 2+ bags ordered). For those avoiding fluoride or chemicals in toothpaste.
Because of its ultra-clean, non-toxic formula, Larineco gum is even safe for kids, especially older children and teens. Making it a gentle, holistic way to help strengthen their teeth without harsh chemicals. If you’re looking for a fluoride-free, chemical-free option to support healthy teeth, Larineco gives your kids (and you) a safe, natural alternative that works.
✅ Pros
❌ Cons
Why it’s best for kids too
Larineco’s natural, fluoride-free, and chemical-free formula makes it ideal for children. No risk of overexposure to fluoride, and it avoids choking hazards by staying intact longer than ultra-soft gums.
What Real Customers Are Saying
Surprisingly effective!
I’ve been using this gum every day and noticed my gums feel firmer and my sensitivity is practically gone. I honestly didn’t think a gum could help so much, but it really does — Carla M
Even my dentist noticed the difference
I used to dread my dental checkups because of constant cavities. This time, my dentist was impressed — no cavities at all! Plus, my breath stays fresh for hours. I’ll never go back to regular gum — Jason K
I’m amazed at the results
Since I started chewing this gum, my teeth feel sturdier and my gums have stopped bleeding when I brush. Honestly didn’t expect such big results from something so easy to use — Emily
Bottom Line
Overall, Larineco Remineralizing Gum impressed us as a game-changer for oral health. It addresses the full spectrum – cavities, gum disease, bad breath, and stains. Using naturally derived, research-backed ingredients. It’s easy to pop a piece after meals or whenever convenient, making consistent oral care achievable even for busy folks. For anyone looking to prevent dental problems or boost their oral hygiene in a simple, natural way, Larineco is our top recommendation.
#2: Underbrush™ Remineralizing Gum (Mastic Mint) – Natural Gum Resin Formula, Great Alternative
Runner-Up – Underbrush Gum (by Nathan & Sons) is another excellent remineralizing chewing gum that we found highly effective for oral health. In fact, Underbrush was one of the first products to popularize this concept of a “tooth-friendly gum” using 100% natural tree saps and minerals. It’s handcrafted from a blend of traditional botanical resins — including chicle, mastic, spruce, acacia, and myrrh gum — combined with nano-hydroxyapatite and xylitol. Like Larineco, Underbrush Gum is designed to kill bad bacteria, freshen breath, fight plaque, and rebuild enamel while you chew. If you want a more natural/old-school resin chewing experience that still delivers modern oral care benefits, Underbrush is a fantastic choice.
✅ Pros
❌ Cons
Bottom Line
Bottom Line: Underbrush Remineralizing Gum offers nearly all the same benefits as our top pick – stronger enamel, fewer cavities, healthier gums, and fresh breath – delivered in a purist natural format. We recommend it for those who want a gum with a bit of history and heft: chewing on Underbrush feels like going back to basics (real tree sap gum) while still getting cutting-edge dental protection. It’s an ideal runner-up and a testament to how effective a well-formulated gum can be for oral care.
#3: Spry Dental Defense Xylitol Gum – Simple, Affordable Cavity Fighter (Budget Pick)
Budget Pick: Spry Dental Defense Gum
For an affordable, widely-available option, we recommend Spry Dental Defense Gum. While it lacks the mineral-rich formula of Larineco or Underbrush, it delivers one proven benefit: high-dose xylitol. Each piece contains about 0.9g of xylitol, which helps starve cavity-causing bacteria, reduce plaque, and even reverse early signs of tooth decay by promoting remineralization.
Spry is a solid daily “maintenance” gum for freshening breath and protecting enamel on a budget. It comes in several natural flavors like Peppermint, Cinnamon, and Fruit, with a soft texture and pleasant chew. While it doesn’t repair enamel or target gum health like our top pick, it’s a good choice for everyday use.
✅ Pros
❌ Cons
Bottom Line
If you’re primarily looking for an inexpensive gum to improve oral health, Spry Xylitol Gum is the best bet. It’s a smart swap for sugary or artificially sweetened gums, as it actually benefits your teeth each time you chew. While it’s not as revolutionary as our top picks, it’s a proven, no-fuss option that’s helped many people get fewer cavities. We recommend Spry especially for those new to oral health gums or anyone who wants a cavity-fighting gum the whole family can use (it’s safe for kids too, since it’s just xylitol and no questionable additives).
Conclusion: Larineco Leads the Pack for a Reason
All three gums we’ve reviewed can play a role in a healthier oral care routine, but Larineco Remineralizing Gum emerged as the clear winner due to its unique all-in-one approach. By tackling enamel remineralization, gum healing, breath freshening, and whitening simultaneously, it offers the most comprehensive benefits – which is exactly the angle that resonated most with us and, we suspect, will be most impactful for users. When you consider the widespread issues of cavities and gum disease, a product that specifically addresses both tooth strength and gum health stands out as especially valuable. Larineco’s formula, backed by dental science and glowing reviews, makes it a compelling choice for anyone looking to elevate their oral health in 2025.
While Underbrush Gum is a very strong alternative (and the pioneer in this category of natural remineralizing gums) and Spry Xylitol Gum is a great budget-friendly cavity fighter, Larineco’s superior blend of ingredients and results put it a step above. It came out on top in our testing for delivering noticeable improvements in a short time, from fresher breath and less plaque to whiter teeth and happier gums. If you’re ready to chew your way to a healthier smile, Larineco Remineralizing Gum is our top recommendation to try first, backed by a 60-day guarantee and the highest praise from its users. Your teeth and gums just might thank you with fewer dentist visits down the road!
