Opalescence 20% Tooth Whitening Refill Equipment (2 Packs / 4 Syringes) Carbamide Peroxide. Made by Ultradent, in Mint Taste. Tooth Whitening Refill Syringes – B-5196-4

5 stars
My dental hygienist recommended this product to use in my custom made trays. I have people ask me ALL the time how my teeth are so white. It’s been over a year since I whitened with this, and I still get compliments all the time from both friends and strangers. I only do 30-45 minutes for 3-5 days or until I’m happy with the results. Repeat every 8-12 months or when you notice it’s time to refresh. For me, it’s every 12 months because I am not prone to yellowing/ staining. Picture was taken a year after using product, and I drink coffee almost every day. A little goes a very long way! As long as you don’t overfill, you will not bleach or burn your gums. If any gets on your gums, immediately wipe it off.

Great product so far !
Already can tell it’s a better quality than EZGO ! It’s way thicker and just seems better quality ! Stays in trays very thick not like EZGO at all ! EZGO was like water compared to this brand ! Better taste too and because it’s so thick it’s not all in my mouth either ! This is my first use so I would have given it 5 stars but not sure how good of a job it will do long run but so far so good !

Works and it didn’t hurt!
As a coffee drinker of 20 years I desperately needed a teeth whitening. I have super sensitive teeth and gums so I was worried whitening treatment would hurt. My dentist actually recommended buying this gel online rather than his office since it’s cheaper. The directions said I could use my Invisalign retainers, which I happen to have. If you don’t have them you can get trays from the company too. I used the gel every other day for 4 hours at a time and my teeth are white again. The yellow teeth were embarrassing and made me look older. Now I have a younger and fresher look.

not like it used to be…
I have used this for years. Usually, 2 syringes over 2 or 3 days (to preserve my gums) would yield noticeable results. If I were going on vacation or had an event, I’d do it for 3 nights over 5 days and results were awesome. The last batch I received in Nov 2023 had an expiration date of Oct 2024. The packaging was sealed. When I purchased from my dentist, he always had it in the fridge and mentioned that prolonged the life of the product, so I always refrigerate after it comes. This last time, it just didn’t perform like other times and there was little whitening. With a year before expiring, I don’t know why, but also don’t know how old it can be and still considered fresh. Packaging looked the same but syringes seemed a little smaller and a bit flimsy compared to the past. The little end tips used to twist off easily but this time, the whole end came off up to the barrel of the syringe and was difficult to distribute in the dental traps. Not cool. The missing info could be how the product is stored before delivery to the end user and under what temps it is shipped. I’m going to try the new “Opal” product this time. I don’t know if it’s the same product as before with new packaging, but it HAS to be fresher.

I try it before and it was amazing bleaching process
