Description

Opalescence Go 15% prefilled teeth whitening trays provide convenient whitening at home or while traveling. The discreet UltraFit trays are prefilled with the optimal amount of mint-flavored whitening gel and adapt comfortably to most smiles for broad tooth coverage. No impressions, custom trays, syringes, lab work, or LED whitening lights are required. Wear the trays for 15–20 minutes daily as directed. 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? Opalescence is one of the most clinically studied professional teeth whitening brands and was developed by dental professionals. Its prefilled trays are made in the USA from globally sourced materials, are easy to use, require no LED light, impressions, lab work, or custom trays, and are designed to provide fast, noticeable results. When used as directed, the whitening system is designed to provide comfortable and gentle whitening for your teeth. Opalescence is trusted by more than 25,000 dentists, and reviewers consistently praise how much simpler and more convenient the prefilled trays are compared with traditional whitening strips. With over 30 years of professional whitening experience, more than 50 teeth whitening awards, and over 100 million smiles brightened, Opalescence is recognized for professional-quality teeth whitening. What options are available? Opalescence Go is available in 10% or 15% hydrogen peroxide concentrations and Mint or Melon flavors. It is vegan, contains no animal- derived ingredients, and is certified gluten free and certified kosher. Can Opalescence Go be used with braces? Yes. 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.

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? Opalescence Go 10% is generally recommended for people with greater tooth sensitivity because of its lower peroxide concentration and gentler whitening approach.

Compared with Opalescence Go 15%, the main difference is the recommended wear time.

Opalescence Go 10% is especially suitable for people who experience greater tooth sensitivity or prefer a gentler whitening option. Can Opalescence Go be used with braces? Yes.

  • Great results! Can cause sensitivity.
This item works!! This can cause some sensitivity, so maybe skip a night or two. It’s being used with daughter’s retainer. This was recommended by the orthodontist and I’m happy with the results.

  • The same product my dentist gave me with one exception.
Last year before some dental work my dentist had me use this product to whiten my teeth and it was superb. I'm not sure how exactly it's measured but I was able to get a really good shade of white on my teeth. He had a custom plate made for my upper and lower teeth, but due to the work i could no longer use them. So to freshen up my teeth I had the choice to buy this brand in pre-filled trays or to buy this syringe and make my own custom trays. I chose to buy the mouth guards that you dip in water and form the mold. It was easy to do, and I'd highly recommend going this route. When you have your own custom mold, you can focus on using the syringe on the front part. Keep them in the fridge. Once you open the syringe (applicator?) one of those will last 3+ uses, you really don't need much. This is professional grade. It comes in various strengths. 10-15 I think you leave in your mouth 4-8 hours, 20% is recommended for 2 hours. Higher concentrations are meant for shorter uses, but the higher you go the more chance you have for sensitivity on the tooth and gums. When you do a custom tray, leaving it in your mouth for two hours is no big deal. ... show more

  • Lesson Learned
I had previously tried the 33% but it was too much “burn”, if you will, especially if the gel made contact with the gums. The 20% works great and way easier to tolerate. Package has four Gels. I use two on the top and two on the bottom … usually 4-5 applications using two syringes on each.

  • This Works! No Sensitivity.
The gel works. But i use it with my mouth tray made for periodontal gel. One syringe is adequate for two treatments. Only use a small dot on front teeth. More is not needed. Read instructions and leave on according to instructions for strength. Happy to find this. Much better price than dentists and same product. Absolutely no sensitivity. ... show more

  • This One Actually Works
I got the 22% and the 33%, both work great! Only one I’ve seen results after two treatments. I smoke and drink coffee and occasionally dark soda, so my teeth weren’t very white but now they don’t have that yellow tint and are starting to look “normal” white. I did one treatment each strength a week apart, no sensitivity. Just remember that these are maintenance products and might not give you that glaring white like from professional results. ... show more
