Opalescence 10 before and after

What affects the results seen with Opalescence 10?

Opalescence 10 results depend on starting shade, stain type, wear time, and restorations, so before-and-after photos need context.

What type of whitening system is Opalescence 10?

Opalescence 10 is a carbamide peroxide tooth-whitening system used in a tray. Carbamide peroxide breaks down to release hydrogen peroxide, which oxidizes stain molecules in enamel and dentin.

How can you use the whitening tray safely and consistently?

Use the tray and wear schedule supplied for your product, keep gel off the gums, and record shade changes in consistent lighting. Do not expect crowns, fillings, or veneers to whiten like natural teeth.

Which whitening symptoms mean you should stop and seek advice?

Stop and seek advice for marked sensitivity, gum burns, ulceration, or pain. A dentist should assess darkening from decay or trauma before whitening.

What should you ask about shade, tray fit, and restorations?

Ask what type of discoloration you have, whether the tray fits correctly, and how existing restorations will affect the final shade.

Why do online before-and-after photos differ?
