W | Teeth Whitening Kit

You will see maximum results after 6 consecutive daily uses. We recommend using your Kit at night after brushing your teeth.

We recommend using the Kit once every 2 weeks to maintain your results.

Our Teeth Whitening Kit includes our whitening gel formula and LED light that delivers results in as little as 10 minutes. Our Teeth Whitening Gel uses PAP to oxidise stains, during which process, smaller and lighter coloured compounds are generated which creates a whitening effect.

We recommend using 1/4 of the syringe on the top and 1/4 on the bottom of the mouth tray (1/2 syringe total). If you find this is too much, you can reduce the amount to suit you.

Our Teeth Whitening Gel Refills are for when you have completed the initial 6-day application process and are now looking to maintain your results. The Gel Refills are for lasting results and are to be used once every 2 weeks.

You will get 6 uses out of the Gel Refills, which is 2 uses per syringe. If you find that this is too much you can adjust it to suit you, however, please note this is our recommended usage to achieve best results.

You will need to use the LED Light & Mouth Tray to whiten your teeth correctly with the gel refills. If this is your first time using W-Teeth, our Teeth Whitening Kit is the best option and has everything you need to get started. You can order this product here.

Brush your teeth thoroughly, remove plastic and reinsert the batteries with the writing side facing up. Attach the mouth tray to the led light. Twist off the gel syringe cap and apply 1/4 of the gel to the top face of the Mouth Tray and 1/4 to the bottom face of the mouth tray (the part that comes into contact with the front of your teeth)Put it in your mouth and turn the light on Whiten for 10 minutes, the LED light will automatically turn off after this time, Rinse you mouth out with water to remove excess Gel. Repeat for six consecutive nightly applications.

Not at all! Our formula has been specially developed to ensure that you will not encounter any sensitivity.

Every pregnancy can be completely different, so we recommend consulting with your Doctor or midwife prior to using W-Teeth regarding any health concerns you may have.

For hygiene reasons we recommend keeping your W | Whitening LED Light & Mouth Tray all to yourself. You can of course share the Gel Refills, however, for maximum results it’s best to use the full course as directed.

We recommend waiting until your braces are removed before using our Teeth Whitening Kit to avoid uneven whitening.

Our Teeth Whitening Kit is recommended for ages 12 years and up. If you are under the age of 18 we recommend getting parental consent before purchasing any W-Teeth products online.

Veneers and caps aren’t designed to be whitened and require special care from your dentist. This also includes crowns, fillings, bridges and dentures. The Teeth Whitening Kit works to remove surface stains from natural teeth. 

Yes, our Teeth Whitening Kit is suitable for all teeth. We just recommend applying a small portion of Gel directly to the teeth as well as the mouth tray before application. The mouth tray is made from a soft flexible rubber that fits comfortably to the shape of your mouth and teeth. Our Teeth Whitening Pen is also great for those hard to reach places.

A build-up of excess saliva while using our products is completely normal and won't affect the outcome of the whitening process at all. If you find that the build-up of saliva is becoming too much during your applications, simply spit any excess into the sink. Our formula is made with safe ingredients so if you accidentally consume a small amount of Gel during your applications it won’t be a problem.

We recommend using the gel syringes within 12 months of opening them. Ideally, it’s best to store your product in a cool dry place, out of direct sunlight during this time, your bathroom drawer or cupboard is perfect.

The LED light takes 3V coin batteries (CR2450). You can find replacement batteries on Amazon, in your local supermarket, chemist, or department store. Feel free to message our Customer Experience staff for a direct link for your location.

No, the LED Light isn’t waterproof as it does contain two batteries. Make sure you detach the mouth tray from the LED Light prior to rinsing.

Our Mouth Tray is made of silicone so it's super flexible to fit any mouth shape or size.

Our updated formula contains a new active ingredient called PAP. This is proven to not only whiten teeth as effectively as traditional whitening ingredients but like our last formula, has been shown to be non-damaging to the enamel and does not cause tooth sensitivity. Our other key ingredients Potassium Nitrate and Hydroxyapatite, have been included to remineralize teeth and help with immediate sensitivity.

Yes. The entire W | Whitening range, including our new Gel formula, have been designed with safety and results in mind. Unlike other whitening agents, PAP does not cause enamel damage and tooth demineralization which are the primary causes of tooth sensitivity. We have also included Hydroxyapatite to strengthen teeth over time as well as Potassium Nitrate for immediate sensitivity protection.
