A juicy watermelon twist on Boka's signature hydroxyapatite toothpaste — a flavour the whole family will actually fight over.

Boka Whitening hydroxyapatite Toothpaste in Watermelon Mint is built around hydroxyapatite (HA), the same mineral that makes up 97% of tooth enamel. It cleans thoroughly and helps lift surface stains for a brighter-looking smile — gently, and without peroxide.

The toothpaste is 100% biocompatible and meticulously crafted to be free from fluoride, sulfates, parabens, and artificial flavours and colours — and it's safe if small amounts are accidentally swallowed, which makes it a popular pick for households with kids who are still mastering brush-and-spit.

The flavour is the fun part: a burst of juicy watermelon rounded off with a touch of natural mint. Fruity enough that kids look forward to brushing, fresh enough that adults don't feel like they're using a children's toothpaste.

Soothing aloe vera, xylitol — a plant-derived sweetener popular in oral care — and antioxidant-rich green tea round out a formula that keeps every brush clean, fresh and enjoyable.
The Benefits.

  • Hydroxyapatite (HA): the same mineral that makes up 97% of tooth enamel.
  • Gentle Whitening: helps lift surface stains for a brighter-looking smile.

FAQ

▸ What does Boka Watermelon Mint taste like?
Sweet juicy watermelon balanced with a crisp mint finish. It's fruit-forward without being sugary — the watermelon sits on top, the mint provides the clean breath finish. Popular with anyone who finds traditional mint boring.

▸ Is it good for kids?
Yes — Boka Watermelon Mint is a big hit with older kids who don't like peppermint. Because it's fluoride-free, it's safe if small amounts are accidentally swallowed. Suitable from around age 3+ with supervision.

▸ Is Boka fluoride-free?
Yes. All Boka toothpastes are formulated with hydroxyapatite (HA) — the same mineral the enamel is made of — instead of fluoride. They're fluoride-free and SLS-free, with no artificial dyes or preservatives.

▸ Who makes Boka?
Boka is a US-based natural oral care brand that pioneered mainstream hydroxyapatite toothpaste in the West. The brand is fluoride-free and SLS-free, with a focus on clean formulations and approachable flavours.

▸ Does it actually taste like watermelon?
Yes — unlike some 'fruit flavoured' toothpastes that taste artificial, Boka's flavour profile leans on natural extracts. The watermelon is bright and clear, balanced so it doesn't become cloying.

▸ How does it compare to Hismile watermelon?
Both are fluoride-free fruit-mint toothpastes. Boka includes hydroxyapatite — the same mineral the enamel is made of — which Hismile's flavoured range doesn't have. If you want a fruity toothpaste with hydroxyapatite included, Boka is the choice.

Switched from a mainstream brand to Boka and haven't looked back. The texture is smooth, not gritty like some natural pastes. My teeth feel genuinely clean after brushing, not just minty. The Watermelon Mint scent is lovely and subtle. A bit pricier than supermarket options but absolutely worth it for the quality ingredients.

Finally found a toothpaste that actually works for sensitive teeth! The nano-hydroxyapatite has made a noticeable difference in just two weeks. My dentist even commented on how much healthier my enamel looks. Love that it's fluoride-free and SLS-free too. The Watermelon Mint flavour is refreshing without being overpowering. Will definitely repurchase.

Great toothpaste overall. I appreciate the natural formulation and the fact it doesn't contain SLS. The Watermelon Mint flavour took a day or two to get used to coming from a conventional mint, but now I prefer it. My mouth feels fresh for hours after brushing. Only wish the tube was a bit bigger for the price.

Good natural toothpaste option. Cleans well and the Watermelon Mint flavour is nice. I do find it doesn't foam as much as regular toothpaste, which took some getting used to, but that's because there's no SLS. Overall happy with the purchase and would recommend to anyone looking to switch to a cleaner oral care routine.
