• Safe

    Opalescence take-home whitening gels are available from your dentist only. The sticky, viscous gel won't leak out of the tray onto your gums, and Opalescence gels include potassium nitrate and fluoride (PF). Findings have confirmed that the potassium nitrate and fluoride actually help to reduce cavities, minimize sensitivity, increase enamel hardness, and improve the overall health of your teeth. 1–5

  • Effective

    Powerful, professional-strength Opalescence take-home whitening gels are available with 10%, 15%, 20%, and 35% carbamide peroxide concentrations. Opalescence take-home whitening gels can provide results after just one treatment, though you should expect to see noticeable results in about a week.

  • Customized

    Opalescence take-home whitening gel is delivered via a customized bleaching tray that your dentist will create from an impression of your mouth. This customization is part of why Opalescence take-home whitening gels are so effective. You can further customize your experience with Opalescence take-home whitening gels by choosing from the four concentrations and three flavors (Mint, Melon, and Regular).
