How does Opalescence GO whiten eligible natural teeth?
Opalescence GO is a preloaded take-home whitening tray system that uses peroxide gel to lighten eligible natural tooth enamel and dentin.
The product name refers to a take-home whitening system with a disposable tray containing carbamide peroxide gel. Peroxide breaks down into reactive oxygen species that alter stain molecules within tooth structure.
Which teeth and restorations can Opalescence GO whiten?
Whitening changes natural teeth, not porcelain crowns, veneers, fillings, or composite bonding. Existing restorations may therefore look different after surrounding teeth lighten.
A dentist should check for cavities, leaking restorations, gum disease, exposed roots, and sensitivity before whitening; follow the prescribed wear time and discard the tray after use.
