The 44% Ganencsnc teeth whitening gel refills box arrived nicely sealed in a thin plastic coating. This gave me assurance that the product was not tampered with or otherwise contaminated since leaving the manufacturer’s production site in China. All ten individual gel refills and the associated items were shipped enclosed in a resealable thick aluminum bag. The light blocking bag is essential as the gel formulation will degrade over time when exposed to strong light. The resealable light blocking bag will help ensure that the gel formulation will remain at maximum strength when stored. The enclosed directions indicate the gels have a shelf life of up to 36 months. Inside the resealable bag, there are the ten individual 3 ml gel refills, ten extensions that can be used to help dispense the gel individual teeth indentations on your mouth mold, directions for use and storage and a tooth shade guide that can help the user access how effective the whitening process is performing. Since these are refills, there are no whitening trays or whitening lights included. This formula is designed to be used with a whitening light and a gel tray so it is not a beginner kit. The directions on use are straightforward and concise. The gel is designed to interact with a whitening light for 16 minutes. The directions include how to prepare your teeth for application and then how to rinse your teeth afterward. The directions also include storage directions and cautions. The manufacturer does caution that this is a very strong formula. If this is the first time using a whitening tray and gels, the manufacturer recommends starting with their 35 % formula which is less likely to sensitize teeth or cause gum irritation. While my feeling is that individual results may vary, my experience has been that Ganencsnc teeth whitening gels are extremely effective at removing stains and restoring a natural white smile. The cost is the equivalent to what a person would pay for teeth whitening kits in a large pharmacy retail store. Everything that is under the control of these teeth whitening gels has been manufactured with foresight and excellent quality control. This is a five-star product. Read more

I was looking to replace some whitening gel for trays, and this seemed like a good option as it matched the strength I had used in the past. I'm pretty impressed with it! I didn't take photos for comparison in this case, but to my eye it seems to have done a similar job to the more costly gels I have owned. I do recommend not leaving it on for more than 30 minutes at a stretch; I left on for two hours at one point and it ended up irritating my teeth. Read more

I am giving this teeth whitening gel a five-star rating because of its convenience and fast acting ingredients. After the first use I did notice a change in the color of my teeth as they were indeed whiter. The first time I used the product some of it leaked out of my whitening tray and onto my gums. I did not experience any irritation and the product continued to whiten my teeth. I am now on day number four and my teeth are even whiter than before. I will continue to use for the time given in whitening teeth to to determine the maximum results. I don't use this product everyday as I do have sensitive teeth and I don't want to have any issues. But I can say that I have not had any problems with the sensitivity of the product. The syringes are convenient for storing away and grabbing when needed without taking up a lot of space in my bathroom drawer. I do recommend this product and a little bit goes a long way. Although it does not come with trays I use my retainers in place of dental trays for whitening and they work just fine. Having 10 syringes of this whitening product means that even after I have gone through the whitening phase, I still have some left for touch ups as I need to apply. This is a great product I do recommend as the cost for professional whitening is much more expensive than an at-home product that you can use at your own pace. The cost is minimal and I would buy again. Read more

These 10 pre-filled syringes are speciffically made for the 'Ganencsnc' LED Light Tray, which is also available on Amazon. These refill syringes are enclosed in a sterile package. The tips and the syringes that are filled with the whitening formula are high-quality made. It comes with good usage instructions, and also comes with a teeth shade guide that you can hold up to your teeth to evaluate your whitening progress. After using for only about a week, I can defintely see a brightness in my teeth. Your gums can be irritated by the peroxide in the gel, but it does not last long after your treatment. I am very happy with this product and would definitely recommend it. So much less expensive than a dentist would charge as well! Read more

These Ganencsnc teeth whitening gel refills are easy to use and worked well for me. After the first use, my teeth appeared a bit brighter within a few hours. As noted in the listing, a whitening tray is required but not included. The gel comes in prefilled applicators, which makes it easy to place the gel into a tray. Each applicator has a cap so it can be resealed for later use. The package includes 10 applicators with 3 ml of gel each, basic instructions, a shade guide to help track changes, and a resealable light-blocking bag to store the gel. Because my teeth can be sensitive, I chose to use the gel every 3 days and I haven't had any issues so far. Overall I’m pleased with this purchase and feel it offers good value for the price.

This teeth whitening gel is incredibly effective at reversing stains from coffee and other common culprits. After just a few uses, I noticed my teeth becoming noticeably whiter. As a refill kit, it doesn’t include trays, but if you already have a set, this product works well, just apply the gel to your trays and put them in. The formula is gentle yet powerful, ensuring minimal irritation and no sensitivity, making it suitable for most users. I had no issues with sensitivity I did wait 48 hours between sessions. It's easy to use and offers excellent value, especially for those looking to maintain their smile at home without expensive dentist visits. Highly recommend giving it a try! Read more
