Will it make my teeth sensitive?

It will not make your teeth sensitive. Our formula has been specially developed to ensure that you will not encounter any sensitivity.

How long will my results last?

Without maintenance, results will last between 3-4 weeks depending on your diet and/or consumption of dark foods and drinks like alcohol and coffee. Applications every 2 weeks is recommended to maintain your results.

How many times do I have to use the kit to get results?

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


How does the Kit work?

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.

Can I use the kit with braces?

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

You may be able to use the Kit with a retainer however this will depend on the sort of retainer you have. Our best recommendation is to speak with your dentist prior to using TwentySmiles.
