the trays around your teeth

How do I use Advanced Whitening Strips?

It’s as easy as 1.2.3… 

In each pouch there are 2 strips (1 upper,1 lower ) in each pouch. We offer 20,30,40 and 50 strips in total.

1) TEAR - To begin, tear carefully at the top of the pouch to reveal the strips inside.

2) APPLY -Take the longer strip first from the plastic film, place the gel side of the strip against your top teeth. Repeat the process with the other strip to the lower teeth

2) REMOVE - Once you complete your session, remove the strips and discard, lightly brush your teeth with warm water to remove any excess gel. Reveal your new Crystal White Smile and enjoy!


For best results, dry your upper and lower teeth before using the strips

We recommended using a mirror to guide the strips in place.

Apply each strip individually, top teeth first then the bottom teeth.

Press the strip firmly against your teeth using your fingers for alignment. Whist doing this, breath air in a fast motion, sucking the strip against the teeth.

Use the strips for up to 30 minutes a day. 

Do not eat or drink foods with colouring agents in during your chosen whitening course

Smoking is not recommended during the whitening process
