The Solution to
a Brighter Smile

Teeth whitening is a popular cosmetic treatment used to brighten your smile. Following an initial consultation at Green Square Dental, we will create your custom whitening trays and provide you with your at-home treatment. 

Green Square Dental is proudly a Polanight by SDI provider.


Benefits of Polanight by SDI


With two concentrations of teeth whitening gel, you can tailor your treatment to suit you.


Taking impressions of your mouth to create your trays, your treatment is bespoke to you and designed to be as comfortable as possible.


You can decide how long you wear your trays for, depending on your desired results. This can vary from as little as 4-6 hours to 8-10 hours per day (overnight).

How Does Polanight Work?

We will take a 3D scan of your mouth to create custom teeth whitening trays, designed to fit your mouth comfortably and hold the gel.

The Polanight gel sits in the tray as you wear it overnight, allowing the carbamide peroxide to enter your enamel and do its job.

Teeth whitening occurs as oxygen molecules from the whitening agent spread throughout the tooth and react with the discoloured molecules in your teeth.
