With over 100,000 loyal customers and the title of Australia’s Best Teeth Whitening Kit, Smilie’s rapid rise to cult status is thanks to one thing: it works.

Born from the brilliant minds of co-founders Natalie Wiltshire and award-winning dentist Dr. Daniel Tankard, Smilie was designed to fill a major gap in the market, a professional-level whitening system that’s actually gentle enough for sensitive teeth.

Backed by 15 years of research and developed by a team of over 70 dental pros, it’s no surprise Smilie has become a staple in Aussie bathrooms.

But let’s talk savings, because this sale is next level. The Smilie Birthday Bundle, normally $376, is now just $145.

That’s a whopping $231 off.

Inside, you’ll get:

• The award-winning Teeth Whitening Kit
• A Whitening Gel Refill Pack
• The on-the-go Whitening Pen

A set of ultra-convenient whitening strips

Whether you’re chilling on the lounge with Netflix or doing a quick touch-up before a night out, this bundle has every base covered.

And the best bit? Most users see results after just one go.

Yep, 98 per cent of customers report a visible difference after a single use, and the five-star reviews keep rolling in.

One happy customer raved: “Fantastic! It is easy to apply, no mess, no unpleasant taste, the whitening effect starts the very first time.” Another added: “Very pleased with the product. I saw results within a week or so.”

Smilie has also earned its place on the shelves at Chemist Warehouse and Woolworths, proof that this isn’t just another influencer fad. It’s science-backed, dentist-developed, and real-results verified.

This May, Smilie is going bigger than ever. So if you’ve been putting off whitening your teeth because of cost, sensitivity or the endless mess, this is your sign.

A million brighter smiles (and counting) can’t be wrong.
