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.

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

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.

With products as this, it is best to precursor the review with some instruction and expectation setting: Instructions: --This product is meant to be used as a refill to custom trays fitted by your dentist. Otherwise, you will have issues with uneven application and gum burning. --Application muust follow instructions that are provided. Do not overapply or the gel will burn your gums and turn them white for a little while. Expectations: --At the end of the day, research suggests that the 35% whitens as much as the 15%. The difference is twofold: The 35% needs to onlt stay on for 30 minutes, but the 15% needs to stay on an hour. Second, the 35% will get your teeth whiter faster. E.g., if it takes 12 weeks for the 15% to get to the desired whitening, it may take 8 weeks for the 35%. --The 35% will make your teeth more sensitive than 15%. For me, it was worth the extra sensitivity to get faster results. --It takes time! Results do not occur overnight for most people. Expect 12-16 weeks, applying once a day at night for 30 minutes. If it occurs faster, use the remaining gel to periodically keep them white. --The gum line part of the tooth may still be yellowish. My guess is it is hard to get right to the gum line without burning. So the application will still be a little uneven. My review: I had noticable results after 4 weeks, from 2-4 shades. One tooth was 4 shades, most were 3, and the rest were 1 to 2. I am under Dentist care for the entire process. For the 4 week period, the Dentist was highly pleased with the progress. I was pleased as well. After 6 weeks, though, the progress seemed slower, and the lower teeth are still too yellow. As well, one issue remains: one upper front tooth would not whiten well. It had undergone tramua when I was young. So, the 2 upper front teeth will need veneers. Right now it is a race to whiten as much as possible to get the whitest shade of veneers possible. My method: -- I used 12) 15% gel for 6 weeks that the denstist provided -- I used (8)35% gel for 4 weeks that I bought from Amazon -- I applied twice a day for at least half the time -- I used between 1/3 to 1/2 of the syringe per application In all, you have to be patient and not expect quick results. Some teeth will whiten faster and others may not whiten much at all. From what I researched and the Denist's input, results widely vary. However, you should certainly see viable results and the effort is not hard. 30 minutes after bushing and flossing is pretty easy. I disagree with the low ratings for this product. Just because someone does not use the product properly, does not reflect on the product quality. Results based on non-custom trays are invalid in my opinion and should not reflect on the rating. I would have given a 5 star, but I felt somehow they need to get the gel to the gumline without burning, providing full tooth coverage.

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.

Works well to brighten up my teeth.

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.

تبييض للاسنان من دون تحسسها

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
