Dr Song Teeth Whitening Gel Refill 4X Syringes 35% Carbamide Peroxide

After using Dr. Song's teeth whitening for more than 2 years I finally take the time to give them a well-deserved review. Their kit of <35% carbamide peroxide + light + little applicator brush> is all you need to safely whiten your teeth at home. I first did an "intensive" whitening with daily use until the desired color, and then every now and again for maintenance. This kit costs a fraction of what it would cost to have it done at a dental office. Also, a competitive price compared to all the other home-whitening kits out there that charge you much more for the same results in a fancier package.After several purchases I can tell: It always delivers promptly, is well packaged, and syringes with carbamide come in a bag with an expiration date (this is important as carbamide peroxide will expire and stop working). The product works just as promised. I personally have not had any teeth sensitivity with repeated use. But I think people prone to teeth sensitivity might want to space the treatments to every other day or more.Do not look any further. You are buying a very good product at a great price!

I really like the formulation of this product, for the price point. Works great, it gave me some sensitivity but an equal amount to a 2% Hydrogen peroxide whiting gel I've tried before, which is amazing for the strength of the product (if sensitivity is a concern, get some teeth remineralization gel such as the one from Hismile or products that contains potassium nitrate such as Sensodyne products to reduce sensitivity). Carbamide peroxide is a great ingredient because it continues to work even after absorption into the enamel, unlike hydrogen peroxide (I do my research). I also really like the company as well, in my latest purchase, they even put in an extra whitening syringe as well as a teeth shade chart to track progress.

I’ve been whitening my teeth for years and for some reason the past three years I have not been able to find anything that really works. Dr. songs seems to be doing the job. It doesn’t make your teeth sensitive, but it does seem to be whitening better than others out there.

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 do notice a bit of whitening from this, but not like the 35% that I bought from my dentist(and also from amazon, same brand). I do like that the taste is not horrible, and there is no sensitivity at ALL..but that makes me question the concentration of active ingredients. I have done 5 daily applications to get close to what I could do in 2(spread over a week) of the old stuff. HOWEVER, the price is excellent and if you dont mind sitting with this in your mouth for 30 minutes daily, it does whiten things up.

I was a bit hesitant to try Dr. Song Whitening Tooth Gel, especially as a coffee drinker, but I’m so glad I decided to give it a shot! This product has been perfect for me.I've noticed a significant improvement in the whiteness of my teeth since I started using it. The gel is easy to use and doesn’t have an overpowering taste, making it a pleasant addition to my oral care routine.Overall, I highly recommend Dr. Song Whitening Tooth Gel to anyone looking for an effective way to brighten their smile—especially if you’re a coffee lover like me!

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.
