Opalescence 35% CP Mint - Gel Syringes Teeth Whitening - Refill Kit - Carbamide Peroxide Gel. Made by Ultradent. Tooth Whitening Refill Syringes 5197 (0.04 Fl Oz (Pack of 4))

This teeth whitening product really impressed me with how quickly and effectively it works. After just a few uses, my teeth looked noticeably brighter and more natural compared to other products I’ve tried. It is quite strong, so it’s important to follow the instructions carefully—using too much or applying it too often can make your gums sensitive. As long as you use the right amount and give it time between treatments, the results are excellent.

I've been using Opalescence 35% teeth whitening gel (bleach) since I was 16 and am now in my 30s. If you think $100+ crest white stripes or gimmicky LED light products are the answer... kindly give this a try. Bear in mind you do you need a custom made retainer/teeth tray to use this product. Unlike over the counter teeth whitening products (that just oxidize off stains), Opalescence actually turns your teeth white - if that makes sense. It is a 35% carbamide peroxide, typically dispensed (at inflated prices) at dentist's offices. It comes in 10%, 15%, and 35% variations. The 10% and 15% are meant for overnight. The 35% is for a convenient 30 minutes. This product dramatically bleaches and whitens appearance (in a visibly noticeable fashion) after two or so uses. Consistent use (8-9 times in a row spaced out a few days) will make your teeth glow from outter space. It gives an iridescent optical effect that catches the eye. You will get so many compliments. I'll do it once a year or so and my teeth will be white for like a two years lol. Products incredible. Be cautious not to get the product on your gum line or to leave it on longer than 30 minutes. It will increase teeth sensitivity.

High quality. Works as intended. They noticeably whiten teeth, even after 1 use. They do not make my teeth as sensitive, compared to other products.

Opalescence is the best teeth whitening product I have found. I would buy this directly from my dentist up until he retired. You get the best results from custom made trays, however, using generic whitening strips with the Opalescence gel gives good results as well. Badly stained teeth may need daily whitening to begin, but once a week will keep them maintained. The only downside is that it's a little pricey. I recommend this product.

4 stars because of the price and quantity in the syringe. There are other brands out there that whiten teeth equally as well, offer larger syringes that hold twice as much solution and dont cost as much.

The product works! The sellers are aware it will make your gum and teeth sensitive. in the box there is instructions of how to lower teeth sensitivity when applying the gel. I had the gel on for 2-4 hours and I can see results already. I suggest this but know it will make your teeth tingle. tray is not included. I used my retainer as a tray

Really works, love it great product I will buy it again

The best teeth whitening gel! I’ve used opalescene since you had to buy it from your dentist! It works great and is easy to use!

Best whitening gel on the market- sold at most dental offices. Be careful as it can easily bleach the gums if you do not have properly fitted trays! Only wear them for about 25 mins max. Bleaching goes away in about 2 hours (swish w warm salt water until gums heal).

Nice

Excellent products and excellent customer service as well
