Really works!!
By Brandi on Reviewed in the United States on July 5, 2024
I recently purchased the Opalescence Teeth Whitening Gel, and I must say, it has exceeded all my expectations. This product is nothing short of wonderful! Effective Whitening: The gel delivers noticeable results in a short amount of time. After just a few applications, I could see a significant improvement in the whiteness of my teeth. The difference is remarkable, and I feel much more confident with my smile now. Easy to Use: The application process is straightforward and user-friendly. The gel comes with clear instructions, making it easy for anyone to use at home. The syringe-style applicator ensures precise application, reducing wastage and ensuring even coverage. Comfortable Experience: Unlike some other whitening products I've tried in the past, Opalescence Teeth Whitening Gel is gentle on the teeth and gums. I experienced no sensitivity or discomfort during the whitening process, which is a huge plus. Professional Quality: This product feels like it provides professional-level results from the comfort of my own home. It's evident that a lot of research and quality control has gone into making this gel effective and safe for everyday use. Great Value: Given the impressive results, I find the Opalescence Teeth Whitening Gel to be excellent value for money. The pack contains enough gel for multiple treatments, making it a cost-effective solution for maintaining a bright, white smile.

Not Effective Product Lot or Customer Service
By Dawn Marie on Reviewed in the United States on October 18, 2025
I have purchased opalescence 35% before, years ago and it was some of the best whitening I had used so when I found it on amazon I was excited and got more. But this batch that I received is not good. I’m not sure if it sits too long or is in the heat with travel and warehouse etc. but it is not effective at all. I contacted the company to tell them as I would want to know if my product wasn’t being stored in proper environments or in away that would render it useless. They replied wanting the order number and lot number of the order I received which I sent and then never heard back. So not only is the product not working and was waste of money, the customer service was shoddy. I usually never leave bad reviews, especially for something that might be out of the manufacturers hands, but poor customer service is inexcusable.
