Why do I need Gel Refills?

Our Gel Refills are for when you have completed the initial 6 daily applications with the Teeth Whitening Kit and are now looking to maintain your results. Surface stains can begin to reappear over time so you should use the Gel Refills for lasting results.

You will get 6 uses out of the Gel Refills, which is 2 uses per syringe. We suggest just one use every 2 weeks to maintain your results. This way the Gel Refills will last you 12 weeks. You can adjust it to suit you, however, 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 HiSmile, our Teeth Whitening Kit is the best option and has everything you need to get started. You can order this product here.
