What's the difference between the Teeth Whitening Pens and Refill Gels?

The Teeth Whitening Pen is used to brighten your teeth on the go. It’s compact so it can be taken anywhere and is perfect for use when going out for a meal or drinks. The Teeth Whitening Pen should NOT be used in conjunction with the LED light provided with our Teeth Whitening Kits.

Whitening Gel refills should be purchased for continued use of the Smile & Sparkle Teeth Whitening Kit.

Containing ingredients which help with sensitivity, the Teeth Whitening Powder calms the nerve by forming a barrier over the microscopic holes in your enamel, in the same way, sensitive toothpaste work.
