Teeth Whitening Gel Refill 4X Syringes 35% Carbamide Peroxide

Product works great. Unlike other whiteners this caused me no irritation to the gums at all. I sleep with the mouth piece and gel overnight . The process is quicker and it makes it so much better that there's no irritation in the morning. Perfect whitening product.

I use teeth whiteners on a regular. I drink tea every day. I usually use white strips, however they make my teeth sensitive. I don’t whiten every day, I just whiten as needed. I was finding that the white strips were really making my teeth sensitive. Id want to touch up the area at gum line and between teeth, but didnt want to over due it. Especially when the rest of my teeth were sensitive just a few days ago.I know a Dr that said his colleagues really like this product, so I got on and ordered it. I love that you can put the gel in the area (in the tray) where its at the gum line, vs the way with white strips you have no choice but wrap across the top of the tooth where it can get sensitive. Im not having sensitivity to this. Seems to last days as well ( the whitening after a treatment ). I don't feel like I need to do it often. They still look good days later. I felt like with the white strips, in a couple days they weren't as white already. Love I can put it in the tray more where I need it vs hurting my teeth. Too much whitening can really damage enamel. We don’t want to do that. My IG is TamaraWestCoast you can see if you go there, I like my teeth looking good lol. Im a bit OCD about them.Sorry I wont upload a pic here, not letting Amazon access to all of my photos just to add a teeth pic. Ugh. Why can’t I just add a pic without such craziness.Oh and I love in 10 min you can do this. Doing dishes, out of the shower putting your lotions on or brushing out your hair. 10 min goes fast vs the 45 min with strips. I do add another 10 a lot. If I doing stuff, might as well use the whitening longer. So I usually do more like 25 min to get the most out of the gel.

It’s cheap

Not as White but workable

Don't let the incredibly low price of Dr Song Teeth Whitening fool you into thinking it can only mean it's not as good as what you get from your dentist. On the contrary, it is every bit as good and then some!I had my teeth initially whitened about 10 years ago using a product (I don't want to mention the brand) that my dentist recommended/offered. It did a fantastic job, making my upper and lower teeth a good 5 to 6 shades whiter. My dentist explained that tooth color is largely determined by genetics and your consumption of stain-inducing products, such as coffee, tea, tobacco, and some medications. Depending on my consumption habits, he said, I might need to touch up my teeth every so often. So, when it came time to needing more whitening gel, I contacted my dentist's office. I paid $90 (and that was several years ago) for 8 syringes, each containing the active ingredient, carbamide peroxide, at 20 percent concentration.Then I heard about Dr Song's Teeth Whitening system. After doing a fair amount of research on this product (which contains the same active ingredient but at 35 percent concentration) and on teeth whitening in general, I decided to give it a try. I purchased the Kit initially, largely because it offered not only the whitening gel, but also an accelerator light, a mouth tray (I did not need this, as I'd had customized trays done by my dentist), and several syringes of another gel for gum sensitivity. My dentist's product offered only the 8 syringes of whitening gel -- at 4 to 5 times the cost!Dr Song Teeth Whitening works just as well as the "professional" product my dentist offers. But because of the higher concentration of carbamide peroxide in Dr Song gel, results are achieved much faster. I will never go back to ordering refills from my dentist when I can get professional results at a mere fraction of the cost!

I love this kit! I got gel pens, the light and the tray that attaches to the light that you put the gel into (it's like a silicone mouth guard). I was skeptical at first and a little nervous since I have sensitive teeth but I used it every day or every other day when I started and it made a huge difference. It didn't make my teeth sensitive or hurt at all! I got more results with this gel and light then I ever did with a plain Crest strip. Each syringe can be used for 3 treatments. Just squeeze some into the mouth tray and recap the leftover gel. The gel pen is a little tricky to dispense 1/3 of the gel into the syringe at a time. It tends to over squirt into the tray and sometimes I used more than I needed so I went through the gel quicker than I wanted but they were so affordably that it didn't matter as much to me. Now I just use them once an while to keep my teeth white. I would definitely recommend this. They sell these with or without the light. If you don't have a light, buy their kit w/light. If you already have a light, they sell a set of 4 syringes without the light.

I've always been using these for years! It was great, saw lasting results, love the mouth guard light, don't mind the brush and syringes. However, the last two times I've bought them was bad!!! At first, I thought it was me because I put them in the bathroom. So I thought it was too damp and gets steamy in the bathroom that caused it. However, when I bought these back in October 2024, I put them in a dry, cool place and it still went bad! It's been barely 3 months and it already went bad!! I'm not using this on my teeth!! Wasted my money, I'm not purchasing it from here anymore and neither should you.
