The Whiter Smile Express Kit is your best choice if both you and your partner (or friend) want to whiten your teeth. It’s set up for people who want visible results in the shortest time possible without endless add-ons or extra purchases. Inside the box you’ll find everything needed to start and finish a complete whitening course at home, along with a generous amount of gel so you can maintain your results later with simple top-ups rather than buying refills straight away. The kit also includes a remineralisation gel for after each session, a handy whitening pen for quick touch-ups between treatments, and our compact 6 LED blue spectrum light to support the process while you whiten.
What makes this kit practical is how seamlessly it all works together. You mould the trays to your teeth in warm water, apply the whitening gel, and use the small blue light during your session to help you get the most out of each application. After you rinse, you apply the remineralisation gel to settle any sensitivity and support your enamel so your mouth feels comfortable and ready for the next session. The whitening pen lives in your bag or bathroom cabinet for those moments when you want a fast freshen up before a night out or an important meeting.
LED Whitening Light
The LED light is designed to be used at the same time as the gel. Its blue wavelength is matched to the photo initiator in our formula, which helps the active ingredients do their job more efficiently while you’re wearing the trays. There’s no heat and no abrasion. It’s a simple, lightweight companion to your treatment, created to enhance the whitening step rather than replace it.
Remineralisation Gel
Sensitivity is a common worry, so we’ve made sure the kit includes a dedicated remineralisation and desensitising gel. After whitening, you apply a small amount to the trays and wear them briefly. This step helps calm that zinging feeling some people get and supports the enamel so your course stays comfortable from start to finish. If your teeth are usually on the sensitive side, this extra step makes a noticeable difference to how pleasant the process feels day to day.
Mouldable Mouth Trays
Getting a good fit with the trays is straightforward. They’re made from a flexible material that softens in warm water and then shapes to your teeth as you press them into place. Once they cool, the trays hold that custom fit so the gel sits neatly where it should. We include a third spare tray in case you want to re-mould or make a fresh set, and a hygienic storage case so they stay clean between uses.

USA Dental Lab Made
Our teeth whitening gel is proudly made in the USA, where strict regulations and advanced manufacturing processes ensure the highest levels of safety and effectiveness. Unlike gels produced in countries with lower quality control standards, USA made gels undergo more rigorous testing to guarantee purity, consistency, a more precise formulation, and optimal whitening performance. Additionally, it meets both Australian and international safety regulations, providing peace of mind that you’re using a trusted, high quality product designed for the best possible whitening experience.

Always Made Fresh
Unlike many teeth whitening brands that produce gel in bulk just once or twice a year, we manufacture ours every 2–3 months. This means our teeth whitening gel is always fresher, delivering better results with a longer shelf life. Fresher gel maintains its potency, ensuring maximum whitening power and reduced sensitivity. We’re so confident in the quality and effectiveness of our formula that we offer a satisfaction guarantee - if you're not completely happy with your results, we’ll send you free refills until you are. With our product, you’re getting a premium, consistently high performing whitening gel.

No Dangerous Ingredients
Our FDA registered, Kosher Certified, USP grade teeth whitening gel is made using only the finest quality ingredients - free from harmful fillers or additives. Unlike gels containing animal byproducts, which can irritate soft tissues, our formula is 100% pure, with an optimised pH for enhanced whitening performance and reduced sensitivity. Manufactured under strict guidelines, our gel is lab tested for quality and safety, ensuring a premium, high-performance product you can trust. Plus, all raw materials and auxiliary ingredients are sourced from the USA, guaranteeing the highest standards.
