You should use it once a day. Each whitening session lasts for 16 minutes. We recommend using the kit for at least 12 consecutive days. Then, a maintenance session (once every two weeks) is recommended to maintain the whitening effect.

Phthalimidoperoxyxcaproic Acid (PAP) is the primary whitening agent used in Smile Avenue’s Teeth Whitening Kit which is completely safe for your teeth. PAP oxidizes tooth stains and creates lighter compounds within your teeth to produce a whitening effect. It’s proven to whiten teeth as effectively as traditional ingredients, with the added bonus of not causing enamel damage and tooth demineralization that come with traditional whitening ingredients.

Our gel has been specifically designed to be safe for the gums, tongue and the teeth. You shouldn’t use any whitening product if you have signs of gum disease.

Yes, but veneers and fillings aren’t designed to be whitened and require special care from your dentist. This also includes crowns, caps, bridges and dentures. The Smile Avenue formula works to remove surface stains from natural teeth.

We recommend waiting until your braces are removed before using the Teeth Whitening Kit to avoid uneven whitening. For a retainer, it’s best to speak to your dentist before use.

For hygiene reasons we recommend keeping your Smile Avenue LED light all to yourself. If you really wish to do so, make sure to properly rinse the LED light after each session.

For any refund request, please send us the complete kit as well as dated photos showing your shade before and after treatment to
