Ever wondered if chewing gum could actually help your teeth instead of harming them? That’s exactly what Underbrush Remineralizing Gum promises. Marketed as a sugar-free, plastic-free, natural gum that restores minerals to your tooth enamel, it’s creating quite the buzz. But is it really worth your money—or just another health fad with good marketing?
Let’s dive deep into Underbrush Remineralizing Gum reviews and uncover whether it truly lives up to its claims.

What Is Underbrush Remineralizing Gum?
Underbrush is not your ordinary chewing gum. It’s a functional gum designed to help remineralize your teeth—that is, to restore the minerals that protect your enamel from decay. Instead of being made with artificial ingredients and plastic bases like many commercial gums, Underbrush focuses on natural, eco-friendly components.
It’s available in refreshing flavors like:
- Mastic Mint
- Berry
- Cinna-Mastic
The brand recommends chewing a piece after meals to help combat demineralization, freshen your breath, and support overall oral health.
How Does Underbrush Gum Claim To Work?
So, what’s the science behind this gum? According to Underbrush, their product works by:
- Promoting Saliva Production – Saliva naturally helps wash away food acids and bacteria that attack enamel.
- Delivering Minerals – The gum contains minerals such as calcium and phosphate, which aid in enamel remineralization.
- Maintaining pH Balance – It helps neutralize acid levels in the mouth, which can reduce the risk of cavities.
In simpler terms, it’s like giving your teeth a mini spa treatment after every meal—at least, that’s the promise.
Ingredients Breakdown: What’s Inside Underbrush Gum?
Let’s see what’s inside the pack that claims to be a game-changer for oral health. The exact formulation may vary slightly, but typically, it includes:
- Mastic Gum – A natural resin from the mastic tree, known for its antibacterial and anti-inflammatory properties.
- Calcium Carbonate – A source of calcium that helps in remineralizing tooth enamel.
- Xylitol – A sugar substitute that’s tooth-friendly and prevents bacterial growth.
- Natural Flavors – Like mint, berry, or cinnamon for taste.
- Plant-Based Gum Base – Unlike typical gums that use synthetic plastics, Underbrush uses natural resins for chewiness.
Sounds impressive, right? But do these ingredients actually deliver on their promise?
Is Underbrush Really Plastic-Free?
Yes, and that’s one of its strongest selling points. Most chewing gums on the market use polyethylene or polyvinyl acetate, both forms of plastic, as their base. Underbrush uses tree sap and natural resins instead. This not only makes it biodegradable but also healthier—since you’re not chewing microplastics without realizing it.
If you care about both your health and the planet, that’s a big win.
Does It Actually Help Remineralize Teeth?
Here’s where things get interesting. Some of the ingredients, like xylitol and calcium carbonate, have scientific backing for supporting enamel health. Xylitol reduces harmful bacteria, while calcium carbonate can aid in mineral absorption.
However, the effectiveness of remineralizing gums varies from person to person. The key factor is how long you chew and your oral hygiene routine. While it can support enamel repair, it’s not a replacement for brushing, flossing, or fluoride toothpaste.
Think of it as a supplement to your dental routine, not a miracle fix.
The Taste and Texture Experience
Taste matters—a lot—when it comes to gum. Users have reported that:
- Mastic Mint has a clean, herbal freshness with a hint of tree sap.
- Berry feels mild and slightly sweet.
- Cinna-Mastic gives a warm, earthy cinnamon kick.
The texture is chewier than regular gum, and since it’s natural, it softens quickly but doesn’t become sticky. If you’re used to commercial gum, it might feel different at first—but it’s a small tradeoff for a cleaner, natural product.
Packaging and Eco-Friendly Approach
Underbrush doesn’t just focus on teeth—it also cares about the environment. The packaging is recyclable and minimalist, avoiding plastic entirely. That’s a big thumbs-up for anyone trying to live more sustainably.
Each box contains a small number of individually wrapped gums, making it convenient for travel or post-meal use.
How To Use Underbrush Gum for Best Results
To get the most out of it:
- Chew one piece after meals for at least 10–15 minutes.
- Avoid chewing immediately after brushing your teeth.
- Keep it in your car, bag, or desk for easy access after snacks or coffee.
Remember, consistency is key. You won’t notice results overnight—but with regular use, it may help improve your enamel strength and breath freshness.
Benefits of Underbrush Gum
Here’s what sets Underbrush apart from ordinary chewing gums:
- Supports Enamel Health through remineralizing minerals

Are There Any Side Effects?
Underbrush is generally safe for most people. However:
- Some users may find mastic resin taste unusual at first.
- Excessive use of xylitol can cause mild digestive discomfort.
- If you have allergies to tree resins, consult your dentist before use.
Always remember—natural doesn’t always mean risk-free, but the chances of side effects here are very minimal.
What Are Customers Saying?
User feedback is largely positive. Many reviewers highlight:
- Noticeably fresher breath
- A cleaner mouthfeel after meals
- Reduced sensitivity over time
However, a few customers mention the price is slightly higher than regular gums. Given the premium ingredients and eco-friendly packaging, that’s not too surprising.

You can purchase it directly from the official Underbrush website or select online retailers like Amazon. Buying from the official source ensures you get the authentic formula and can take advantage of discounts or bundles.
Be cautious of third-party sellers offering it at unusually low prices—they might not be legitimate.
Price and Value: Is It Worth It?
A pack of Underbrush gum costs more than your typical convenience store gum, but you’re paying for:
- Better ingredients
- No plastics
- Oral health benefits
- Sustainable packaging
If you value your dental health and want an eco-friendly alternative, it’s worth the investment.
