Teeth Whitening Gel Refill 4X Syringes 44% Carbamide Peroxide

This is a great value - best price for the strongest gel. I only used it twice so far and I'm super happy with the results. Totally works just like another brand I used to buy at twice the price.

I have been using this for the last year, works great.

This is my first teeth whitening product. I have heard of other people using LEDs to whitening teeth before and some using strips. I thought I'd try the LED route because I like lights. That being said I bought the original pack with the device and one refill, which altogether is somewhat cheaper than one pack of strips I believe.I have seen some progress in this gel's ability to combat my collegiate coffee stains from my teeth and will leave the product at 4 stars until I investigate further with likely another refill.5 stars for ease of use but 3 stars for whitening speed capabilities makes for a 4 star product, in my eyes, for now!Thanks for reading my review.

Like most of us here, crawling down within the reviews, the whiteness of my teeth has a newfound importance, even amidst this global pandemic. Glossy, luminous teeth have always been a necessity of attractiveness and a supreme indicator of one's good health. Yet today's appearance-driven world takes this even further, and white teeth and the methods of obtaining such perpetuate the media, and thus each of our lives. Having tried strips and "paints" from the local drugstores, I wanted more, and a thorough search led me here, to an equally effective but safer, less irritating method of whitening--carbamide peroxide.Now, truth be told, Crest's strips whitened, but I could no longer tolerate the sensitivity that accompanied their use, and I sought a substitute equal--or greater!--in effect, and, well, with the utmost certainty, I can say that this is surely that product. These gels are put onto a mouthguard-like applicator, which should be appended onto an LED light, enhancing the overall efficacy of delivery. Ten to twenty minutes of this miraculous gel-osmosis is more than enough, and is likely even less time than a set of strips requires its user to wear. The whitening result is phenomenal, apparent after only one-to-two uses, and accumulates atop of each subsequent application! I have not had one speck of sensitivity either, which is, once more, something I cannot genuinely say regarding Crest's top-tier line, the Professional Supremes.With not a negative in sight, alongside a whitening effect exceeding the most comparable products, I'd pay top dollar for these from Smile Titan (this particular concentration, at 44%, is the highest available on Amazon, and it surpasses in efficacy the gels provided in most all-in-one kits, which hover around 30%), but, somehow, that isn't necessary: these are currently about eight dollars! These are a must-buy; your teeth will whiten, and you will have taken an irrefutable step forward towards (even more) attractiveness!Smile confidently, and look your best!!!

Too much gel comes out at one time - even when slowly pushing the syringe plunger. The syringe hole needs to be smaller. I’ve only used it three nights and so far there’s been no change in my teeth color.

Nearly no results after two tubes of this stuff. Also the black syringe plunger is breaking down and spreading black bits throughout the product. I've used Opalescence in the past and it worked fantastic but thought I'd try this instead. Learned my lesson and will stick with what works.

Ordered the product since the 44% concentration was the highest I could find on Amazon and Smile Titans have it at a very low price tag. I have used the strips in the past but just didn’t get good coverage and hate how they feel.I used some pre molded teeth trays with the gel syringes. On my first use, I used a little less than half a syringe and was careful moving the plunger slowly. I kept the gel on for about 15 minutes and didn’t notice any tooth sensitivity and the taste was fine.I noticed a slight whitening but my teeth are highly stained from coffee. I will keep at it daily till I’m out of gel (8-9 treatments) and hopefully see good results. It likely would have worked better using the LED light so recommend getting the kit.Also, nice to support a small family business!Cheers!

Finally got around to using this a couple months after using it. It does recommend using it with 3 months.Perfect amount for a 10-day or so course. I have molded retainer insert from my dentist, and this stuff worked perfectly with them. I did not use any sort of LED or "light activation" device, just painted the stuff on the teeth part of the retainer inserts and popped them in for 20 or so minutes.I was consistent with time of day and amount for time leaving the product in, and I'm really pleased with the results. My teeth aren't dazzlingly bright white, but they are seriously very much whiter. Also, I was admittedly not the most careful or precise when putting the stuff on the retainer inserts, so some did get on my gums but it didn't irritate my gums or bleach them.Super pleased enough to buy another round to apply in a few months.
