Low-Sensitivity Formula, Melon, Dentist Developed and Made in USA. : Health & Household Review: ⭐⭐⭐⭐⭐ Highly Recommend! - I was honestly impressed with the results. I noticed a visible difference after just my first 1-hour session. The whitening was noticeable right away, and my teeth looked brighter without having to wear the trays all day. I experienced only minor sensitivity, which was actually less than the 10% gel my dentist previously prescribed. I was never even given the option to try a higher concentration, and I’m glad I found this instead. The biggest advantage is the treatment time. One hour is perfect. Ain’t nobody got time to wear whitening trays for 6–8 hours! This 35% gel gets the job done much faster while still being comfortable. If you’re looking for professional-looking results at home with minimal sensitivity and a convenient treatment time, I definitely recommend giving this a try. I’ll be buying it again. Review: Powerful, professional-grade whitening gel that delivers dramatic results fast! - This high-strength whitening gel works remarkably fast to lift years of coffee and tea stains, delivering noticeable brightness in just a few short sessions. The sticky, viscous consistency ensures the formula stays put in your trays without sliding down onto your gums. However, because of the powerful 35% concentration, you need to be precise with application and mindful of wear time to prevent any zingers or gum sensitivity. It is an unbeatable, professional-grade option if you want dentist-level results at home. ## Features - PROFESSIONAL-LEVEL TEETH WHITENING: Opalescence 35% Carbamide Peroxide Whitening Gel delivers professional-quality whitening from the comfort of home. Includes 8 refill syringes, Melon Flavor, each containing 1.2 mL of whitening gel, for use with properly fitted teeth whitening trays. - FAST RESULTS WITH SENSITIVITY SUPPORT: The 35% carbamide peroxide formula is designed for shorter daily applications of 30–60 minutes when used as directed. It contains potassium nitrate and fluoride to support patient comfort and help reduce tooth sensitivity during the whitening process. It may whiten teeth by up to 10 shades in 7 days, with results varying by starting shade, stain type, and frequency of use. - CONVENIENT AT-HOME WHITENING: No LED whitening light is needed or recommended. The easy-delivery syringes dispense gel directly into compatible custom whitening trays, dentist-made trays, retainers, or suitable clear aligners, including Invisalign. Trays are not included. - WORKS ON DISCOLORED TEETH: The thick whitening gel is designed to remain in place inside a properly fitted tray and help minimize migration onto the gums and other soft tissues. It helps lift stains caused by coffee, tea, wine, soda, smoking, and other common sources of tooth discoloration. - TRUSTED OPALESCENCE QUALITY: Vegan, certified gluten-free, kosher, and sweetened with xylitol, which may help reduce the risk of tooth decay. Made in the USA by Ultradent Products using globally sourced materials. Backed by over 30 years of whitening expertise, 50+ teeth-whitening awards, more than 100 million smiles whitened, and recommended by over 25,000 dental professionals. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D3S799XD | | Active Ingredients | Carbamide Peroxide | | Age Range Description | Adult, teens | | Best Sellers Rank | #49,232 in Health & Household ( See Top 100 in Health & Household ) #39 in Teeth Whitening Gels | | Brand | Opalescence | | Brand Name | Opalescence | | Customer Reviews | 4.5 out of 5 stars 216 Reviews | | Flavor | Mint | | Included Components | Applicator | | Item Form | Gel | | Item Highlight | 35% Carbamide Peroxide Whitening Gel for Custom Trays.

I've been using it for some time, and I frequently get compliments about my white teeth. I have fitted trays that I got from a dentist years ago, which helps greatly, but the gel is highly effective and you don't have to wear the trays very long -- I can pop in my trays, go out for a walk, and be done by the time I return. (Personally, I never liked the overnight gels -- I prefer stronger whitening products that you wear briefly during the day.) In addition to being effective, the gel does not cause the gum sensitivity that I have experienced with other products (unless you leave your trays in WAY too long, of course). I will definitely continue to purchase this product! ## Frequently Bought Together - Opalescence 35% with PF Gel Syringes Teeth Whitening - (4 Packs / 8 Syringes) Refill Kit Carbamide Peroxide.
