Smile Booster

Our team spent over a year perfecting it, asking and answering a dozen hard questions:

Could it taste as crisp and hydrating as pure water?
Could it be light and digestible for daily use?
Could it provide an alternative to every drink that poses a risk to your smile?
Could it contain ingredients gentle enough for daily hydration, yet purposeful enough to support oral health?

And this is what we created: Black Tide Smile Booster:
- No added sugar, No added flavours, just water elevated.
- Xylitol: Recommended for years in dental research for reducing cavity-causing bacteria. Now it’s in your water.
- Calcium: The mineral your enamel craves, easily absorbed.
- Balanced at PH 7.5. Crisp, refreshing, and soothing.

Any issues with the product reach out to our friendly and understanding team, who will assist. No fault refunds for 14 days after purchase.

The creator of Black Tide always took care of his teeth. The kind of person who never missed a brushing, never skipped a mouthwash, and even flossed. Daily discipline carved into daily routine, the same for most people. Then one day, without warning, part of a back tooth broke away. A sudden decayed fracture. A living nightmare come true and proof that even the most careful could be blindsided.

That moment turned into a revelation. If vigilance wasn’t enough, what chance did anyone else have? Why was doing everything "right" not enough? The answer was waiting in plain sight: the endless stream of sugar and soda, marketed as feel-good refreshment while hiding the acids that start to eat through enamel within minutes.

It is a quiet war, waged on millions of smiles every day. On adult and child alike.

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 that refused to take away, built instead to give back.

The tyranny of large corporations profiting while our health suffers is coming to an end, one can at a time.

Xylitol

Xylitol is a naturally occurring probiotic, often used as a sweetener. It has been widely studied for its effects on oral health and is commonly recommended by dentists, especially in chewing gums.

Dental Health Benefits

Reduces risk of tooth decay
One of the leading risk factors for cavities is the oral bacterium Streptococcus mutans. This bacterium feeds on glucose from food and is the main driver of plaque formation. Excess plaque can trigger immune responses, leading to gum inflammation and conditions like gingivitis. Xylitol cannot be metabolised by these bacteria. Instead, when they ingest xylitol, their glucose processing pathway is disrupted, which starves and kills them. As a result, plaque levels decrease while beneficial oral bacteria remain unaffected.

Scientific findings Xylitol-sweetened gum has been shown to reduce harmful bacteria levels by 27–75%, with friendly bacteria staying stable. Human studies demonstrate that replacing sugar with xylitol, or adding it to the diet, reduces cavities and tooth decay. Animal studies suggest xylitol can improve calcium absorption, supporting stronger teeth and bone health.

Other Potential Benefits

Ear infections
Because the mouth, nose, and ears are connected, bacteria in the mouth can cause ear infections — especially in children. Xylitol may reduce these bacteria, though recent trials show mixed results.

Yeast infections
Xylitol can interfere with Candida albicans by reducing its ability to stick to surfaces, which may help prevent yeast infections.

Collagen and skin health
Animal studies suggest xylitol may increase collagen production, which could help counteract age-related skin changes.

Bone health
In rat studies, xylitol increased bone volume and mineral content, suggesting potential protective effects against osteoporosis. Human studies are still needed.

Gut health
Xylitol functions like a soluble fibre, feeding friendly bacteria in the gut and supporting digestive health.

Fluoride (SMILE BOOSTER MAX ONLY)

Fluoride is a naturally occurring mineral widely recognised for its role in protecting teeth. It strengthens enamel, reverses early decay, and reduces the growth of cavity-causing bacteria.

How Fluoride Works

Strengthens enamel: Hardens the outer surface of teeth, making it more resistant to acid attacks.

Remineralises teeth: Replaces minerals lost during the early stages of demineralisation.

Reverses early decay: Can repair early-stage enamel damage before cavities form.

Inhibits bacteria: Reduces the ability of plaque bacteria to produce acid.

Benefits

Prevents cavities in both children and adults.

Protects developing teeth in children by creating a stronger, acid-resistant surface.

Saves money and time by reducing the need for dental treatments.

Improves overall wellbeing by preventing decay-related pain, difficulty eating, and social impacts.

Public Health Impact

In the UK, 31% of five-year-olds and 46% of eight-year-olds have tooth decay — the leading cause of hospital admissions for children aged 5–9.

Tooth decay is entirely preventable, yet it continues to cause pain and place strain on NHS resources.

Decades of research show that fluoride, including through water fluoridation, is highly effective in reducing decay.

Safety

At levels permitted under UK legislation, fluoride is safe and effective. The main risk is dental fluorosis—a cosmetic mottling of teeth (often white lines or patches). This occurs in both fluoridated and non-fluoridated areas and is monitored by Public Health England. The proven benefits of fluoride in reducing decay far outweigh this cosmetic risk.

Some people have a personal preference to avoid fluorinated water, which is why we have two options available. So you can make a personal decision.
