Learn how to use Opalescence Go prefilled whitening trays at home for effective teeth whitening with hydrogen peroxide. Step-by-step instructions and tips.

Quick answer

Use Opalescence Go prefilled whitening trays at home by following a simple daily routine: wear the trays for the recommended time, avoid eating or drinking during treatment, and track your progress for best results.

Why choose prefilled whitening trays

Opalescence Go trays come preloaded with hydrogen peroxide gel, so you don't need to mix or measure anything. This makes them a convenient option for at-home whitening, especially if you want consistent application without the mess of syringes or custom trays.

Important safety considerations

Hydrogen peroxide can cause tooth sensitivity or gum irritation if used incorrectly. Always follow the wear time recommended by your dental professional. If you have sensitive teeth, consider starting with the 10% hydrogen peroxide option.

How to use Opalescence Go whitening trays

1. Prepare your teeth: Brush and floss your teeth thoroughly before inserting the trays. Dry your teeth with a tissue or gauze so the gel adheres better. Avoid using toothpaste with whitening agents before treatment, as it may cause extra sensitivity.
2. Insert the trays: Remove the upper and lower trays from their sealed pouches. Place them over your teeth and press gently to ensure full contact. Do not chew or bite down hard. If the tray feels loose, it may not fit well. Stop and consult your dentist for a proper fit.
3. Wear for the recommended time: Keep the trays in for the duration prescribed by your dentist—typically 30 to 60 minutes. Do not eat, drink, or talk excessively while wearing them. Set a timer to avoid overexposure. Over-wearing can increase sensitivity without improving results.
4. Remove and rinse: After the time is up, remove the trays and spit out any excess gel. Rinse your mouth with water. Do not brush your teeth immediately after treatment. Wait at least 30 minutes before brushing to let your enamel re-mineralize.
5. Clean and store the trays: Rinse the trays with cool water and let them air dry. Store them in the provided case away from heat and direct sunlight. Do not reuse single-use trays. Discard them after one wear as instructed.
6. Track your progress: Take photos every few days to compare shade changes. Most users see noticeable results after 5 to 10 treatments. Stop treatment once you reach your desired shade. Over-whitening can make teeth look translucent.
