Opalescence Go can be a convenient whitening option for people with braces when recommended by their dentist or orthodontist. The UltraFit trays are designed to adapt around the teeth and orthodontic brackets while distributing whitening gel across the smile. Whitening gel does not need to physically touch every part of the tooth’s surface for whitening to occur. Because tooth structure is porous and allows the whitening ingredients to diffuse through the enamel and dentin, the tooth behaves somewhat like a sponge. This diffusion process can help whiten the entire tooth, including the area beneath and around the orthodontic brackets. Individual results may vary, and users should follow the advice of their dentist or orthodontist throughout orthodontic treatment. How quickly does Opalescence Go work? Results vary. Some users may notice a subtle difference after the first application, especially with surface stains from coffee, tea, or red wine. More noticeable whitening commonly appears after 2–3 applications, with fuller results after 5–10 treatments. Crowns, veneers, fillings, and other dental restorations will not whiten. How long do whitening results last? For many users, the results of a completed Opalescence Go treatment may last approximately 6–12 months and sometimes longer than one year. People who frequently consume coffee, tea, red wine, tobacco, or other staining products may need a touch-up after 3–6 months. What should you do if you experience sensitivity? Brush before and after whitening with Opalescence Whitening Toothpaste Sensitivity Relief or Stannous Complete 4 in 1, and do not rinse immediately after brushing. Remove excess gel that reaches the gums with a soft toothbrush or tissue. Do not press the trays firmly against the teeth because this may push gel onto the gums and cause irritation. Consider switching from the 15% formula to the lower-strength 10% formula or whitening every other day, every two days, or less frequently. Persistent sensitivity may indicate an underlying concern; consult your dentist before beginning or continuing whitening. How should Opalescence Go be stored? Temperature on transportation is not an issue. Its recommended to Refrigerate upon receipt and store between 36°F and 46°F (2°C–8°C). Why trust Opalescence, and why might you like Opalescence Go?
