There's nothing like a product that goes above and beyond to deliver on its claims. Gum is a good (and slightly unexpected) example. While it's naturally a quick breath freshener, it's also something that can now benefit your teeth and gums.

This is all due to the Nathan & Sons Underbrush Remineralizing Gum, a mastic-based gum that's gone viral thanks to its clean formula and distinctively unique chew.

Underbrush Gum stands out for its firmer, mastic-based chew and a formula designed with oral health in mind

Its texture is part of its appeal. While most gum disappears quickly, this one gives you something you can really chew on for a while. 

Some shoppers have noted that this adds to the experience, especially for those who've been curious about the potential jaw-snatching effects.

At its core, though, Underbrush is all about oral health. It's formulated to support your teeth and gums with ingredients that help replenish minerals lost throughout the day.

It's basically a dental workhorse, inhibiting bacteria to protect your mouth from plaque and tartar while reducing bad breath and gently whitening without sensitivity. So many people have reported just how much better their mouths feel after using the product.

It's free of all of the 'bad' stuff, too. There's no gluten, sucralose, aspartame, or sugar in Nathan & Sons' products. The blend is natural, with ingredients like mastic gum, spruce gum, acacia gum, myrrh gum, stevia extract, and fruit powders.

The ingredients have been scientifically proven to do everything from prevent cavities to reduce inflammation, both of which are key to superior oral health.

The gum has gained a following online, with shoppers calling out its fresh feel and satisfying texture, and noting how it's improved their oral health significantly

One reviewer wrote, 'I genuinely can't believe how great this is. I haven't even finished one pack yet and already ordered four more packs.'

'Excellent product,' another customer agreed. 'It has helped stop my receding gums and no cavities anymore!'

Now is the time to buy, too: If you're a new subscriber, you can take 15 percent off your monthly delivery through May 31, 2026, when you enter SUBSCRIBE15 at checkout.
