Opalescence uses hydrogen peroxide to penetrate enamel and reach the dentin layer beneath. The peroxide oxidises deep stain molecules, making them lighter — without damaging tooth structure or causing enamel wear.

Opalescence Go 15% can whiten teeth up to 5 shades in as little as 10 days with daily 15–20 minute treatments. Individual results vary depending on the nature and depth of staining.

Some users experience mild, temporary sensitivity during whitening. Opalescence formulas include potassium nitrate and fluoride — clinically shown to reduce sensitivity and strengthen enamel. If sensitivity is a concern, try the 10% formula or our Sensitivity Relief Whitening Toothpaste before and after each session.

Results typically last 6–12 months, depending on your diet and oral hygiene habits. Foods and drinks like coffee, red wine, and tea can re-stain teeth over time. A quick top-up treatment every few months keeps your smile brilliant.

The whitening trays and gels are designed for short-course treatment — not daily indefinite use. Our Opalescence whitening toothpastes, however, are safe for everyday brushing and can help maintain your results between whitening sessions.

Opalescence formulas use professional-grade concentrations of hydrogen peroxide that are more effective than over-the-counter alternatives. Our UltraFit™ trays conform to any smile for full molar-to-molar coverage, and every formula contains fluoride and potassium nitrate for safety and comfort — ingredients you won't find in most strip kits.
