Frequently asked questions+
How do I use the Teeth Whitening Kit?
Each Kit comes complete with an LED Light and Mouth Tray, Shade Guide, and 3 Gel Syringes for a total of 6 applications.
The Mouth Tray is a one-size-fits-all design, so getting started is as simple as attaching the Mouth Tray to the LED Light. Apply ¼ of the gel to the top and ¼ to the bottom of the Mouth Tray to whiten both top and bottom teeth.
Pop the device in, press the button, and the whitening process begins. The LED Light includes a built-in 10 minute timer that will automatically turn off at the end of your application. Spit and rinse, and repeat over 6 consecutive days for the best results.
How long do results last?
After your first 6 day treatment results can last between 3-4 weeks. For longer lasting results, try to limit your intake of any dark foods or drinks that stain teeth. This includes coffee and tea, wine, pasta and curry sauces, and even some fruits and berries.
To keep your teeth white and bright, we recommend completing a single use of the HiSmile Teeth Whitening Kit every 2 weeks after your initial round of whitening.
Does it hurt? Will it make my teeth sensitive?
Not at all! You won’t encounter any pain or sensitivity during or after your treatment. HiSmile’s whitening formula includes a number of soothing and repairing ingredients with various anti-bacterial and anti-inflammatory properties, ensuring a pain-free experience.
