How to use your Bright Lab Teeth Whitening System
Every session follows the same steps: switch on, connect, scan, add the gel, whiten. The app guides you through each one and starts the blue light for you.
Before your first session
- Charge the device using only the plug and cable provided by The Bright Lab. The device needs a specific voltage, so do not use another charger. A full charge takes about 1 to 2 hours.
- Download The Bright Lab app from the App Store or Google Play.
- Create your account in the app. You need one to use it, and the app is free with no subscription.
Switching the device on and off
To switch on or off: press and hold the button on the device until you hear a sound.
Is it on? The device can be on even when no light is showing. If you can see it in the app, ready to pair, it is on.
Each session, step by step
Switch on and connect
Press and hold the button on the device until you hear a sound. Open the app and pair the device. You pair it at the start of every session.
Scan your teeth
Place the device in your mouth, without gel, and follow the app to scan your shade. Remove the device when the scan is finished.
Apply the gel
Use one syringe of gel for each session. Apply half of it to the upper tray and the other half to the lower tray, as a thin, even line along the inside of each tray, where the front of your teeth will sit.
Do not overfill, so the gel stays on your teeth and off your gums.
Start your session
Put the device back in your mouth and tap to start the session in the app. The blue light switches on automatically, so there is no need to press the button on the device. The app times the session, usually 15 to 25 minutes.
When the session ends, follow the app, then press and hold the button until you hear a sound to switch the device off.
Light off or light on?


You never need to switch the blue light on yourself. Just follow the steps in the app.
After each session
- Remove the device and rinse the trays, the part that goes in your mouth, under running water to remove the gel. Do not submerge the device in water.
- Dry the device and store it in its case.
- You can brush, eat and drink as normal. Some people avoid coffee, tea and red wine for a short time afterwards.
- Keep the gel in the fridge or a cool, dry place, out of direct sunlight.
Your course
Your Whitening System includes gel for your first course. When you want to whiten again, a gel refill gives you another eight sessions. Follow the plan in the app and do not use the device more often than it recommends.
Missed a day? Carry on the next day. For the best result, try not to skip days.
Troubleshooting
The device does not appear in the app
It is switched off or the battery is low. Press and hold the button until you hear a sound, or charge it with the plug and cable provided, then pair again.
The device will not switch on
Charge it with the plug and cable provided by The Bright Lab for a few hours and try again. Check that the charging pins are clean. If it still does not power on, contact us with your order number.
No light is showing, but I switched the device on
That is normal. The device can be on with no light showing. If it appears in the app, it is on. The blue light comes on by itself when you start the session in the app.
The timer stopped during a session
You can safely finish the session using your own timing. Afterwards, send us a short message through the app or our contact page so we can look into it.
The app will not open
Update the app, restart your phone and try again. If it still will not open, contact us with your phone model and operating system version.
Is it right for you?
The kit is for adults aged 18 and over. It is not suitable during pregnancy or breastfeeding unless a healthcare professional approves it, or for anyone with untreated cavities, gum disease or an allergy to any gel ingredient. Crowns, veneers and large fillings do not whiten. If in doubt, speak to your dentist first.
