The Revolution Will Be Drank

Big Soda. Big Sugar. Same story: packed with sugar, damaging to teeth, sold everywhere. And don't make the mistake of thinking it's just Soda. Thousands of drinks: fizzy cans, “healthy” juices, teas, energy blends, have the same hidden danger. Sugars and invisible acids. Within 1 minute of tasting, those acids attack. They soften the enamel. They weaken the surface. Until you lose.

Brushing and flossing can’t keep up with the modern world. Teeth don’t regrow. They don’t repair. Without the right daily habit, the damage wins. And every sip may take something you can’t get back.

Your smile is one of your greatest assets: confidence, identity, happiness. It deserves better than an industry that erodes it while profiting. We needed better.

So a line was drawn. A stand against Big Soda and Big Sugar was made. No more drinks that harm while they claim to hydrate. No more industries thriving on decay. Out of that decision came something new: a drink made to keep your smile at it's best.

Over a thousand hours went into its making. Ingredient after ingredient tested until we got it right.
Black Tide is crisp, hydrating water with smile-friendly ingredients like xylitol. Every sip keeps your smile strong, confident, and at its best.
Because what's life without a smile?

Your Smile Reveals A Lot. What's Yours Saying About You?

A smile shapes first impressions more than any word you speak. Confidence, warmth, youth, health, and beauty are all judged in an instant. 

Cultural historians even speak of a “smile revolution” in 18th-century Paris. As dentistry improved, good teeth became a visible sign of vitality and social status. From that moment forward, the smile became one of the most powerful assets a person could display. And it still is. Today we know a smile dominates another’s impression in milliseconds and judgements that can last for days. Yet, it's vulnerable to so much of what we consume. What is yours saying about you?

A century ago, people learnt the habit of brushing. It transformed dental health, letting millions enjoy happier, confident smiles for longer. But the world has changed. Now we live in a flood of sugar and acid drinks formulated to hook our taste buds, while their hidden acids begin working against us from the very first sip. 

For those unaware, their smile is under attack in a way humans have never faced. For those aware and for those who care, we need a simple extra hand to swap out the harm for something that helps - keeping great smiles amazing. We have that now, and it's as easy to drink as water. 

Black Tide is crisp, hydrating water made with smile-friendly ingredients, such as xylitol, which contributes to the maintenance of tooth mineralisation. Every sip is designed to keep your smile strong, confident, and at its best.

We already drink water. Now we can choose the best version. We keep all the gains of hydration – for skin, for health, for life – and now include the smile too. A simple, daily swap. At your fingertips. Whenever you want.

Great smiles aren’t luck. They’re smart habits. And this is the easiest one you can make.

These People Never Had The Choice, You Now Do

We kept seeing the same painful stories online: people wishing they had protected their teeth. It inspired us to look at what we consume and create an alternative: a drink that supports you, not harms.

Because science shows that consumption of drinks containing xylitol instead of sugar contributes to the maintenance of tooth mineralisation. Every can is made with xylitol instead of sugar, so it supports your smile while others erode it.
