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.

Very happy with how well these work to whiten my teeth. I will use them again in the future if needed.

These were recommended to me by my make up lady. I am so glad that I got them. They work so great on my teeth and got them so white. I would recommend 👌

Agree with J Lucas. Does not whiten down to the gum line. And leaving on too long and trying to apply down to the gum line results in somewhat painful sensitivity.

I couldn't be more pleased! My teeth look great and I'll buy another package to keep on hand for a monthly "refresh" I think. This 4 pack was half the price of the exact same product sold in my dentist's office. I already had custom molds but I'm pretty sure you could use them with the sport molds that you heat and put in your mouth to shape.

Product works, juts don’t leave for tos long. 10 minutes max. Will burn gums if you leave for more than 10 minutes. Also be ready to use sensitive tooth pastes the next week after use.

Works well to brighten up my teeth.

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).

Excellent products and excellent customer service as well

Es muy bueno

Nice
