## Description

desertcart.com: Dr Song Teeth Whitening Gel Refill 4X Syringes 35% Carbamide Peroxide : Health & Household

Review: Noticeable results and a great value overall - After just a couple of uses, I could already see a difference in my teeth — especially when comparing them to the whitening guide included in the box. It actually works, which is always nice when you’re trying something new. I also appreciated that they threw in an extra syringe of gel; little touches like that make a difference. I had read a few reviews mentioning black specks in the gel, but thankfully mine was completely smooth and clear. The only small issue I ran into was that the gel tends to come out in a thick glob because the syringe stopper sticks a bit, but it’s easy enough to spread around in the mouth trays. The taste isn’t great, but honestly, that’s pretty standard with whitening gels. Overall, this kit delivers what it promises. My teeth look brighter, it’s easy to use, and the value for the price is solid. If you’re looking for a whitening system that actually makes a difference without spending a ton, this one’s definitely worth trying.
Review: Best at home teeth whitening! - 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  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!

## Questions & Answers

**Q: Why weren’t trays included?!**
A: Because it’s a refill.

**Q: How much is in each syringe?**
A: 3ml per syringe

**Q: Did you feel the product working (bubbling, causing sensitivity)--even a little bit--right away?**
A: No and there was no sensitivity to the teeth or gums. Really like this product. I've used other products that caused sensitivity. Hydrogen peroxide products typically cause that bubbling sensation, not Carbamide peroxide.

**Q: do these have to be refrigerated like other teeth whitening products?**
A: They do not

### ⭐⭐⭐⭐⭐ Best at home teeth whitening!
*by B***B on May 23, 2022*

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).

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!

### ⭐⭐⭐⭐ Great product, not so great packaging
*by N***R on October 19, 2020*

I'd like to give this a 5 star rating, but have to take off a star due to packaging. The product itself works, just like any other 35% solution (most of which are much more expensive). I have regular trays (not the light activated ones), used this for 10 minutes the first time, and saw significant improvement! I generally use 35% solution for 3-4 days consecutively, then I'm good for at least a month or 2. I've done 2 treatments and still have about 25-30% of a syringe left, so a little goes a long way. My complaint is in the packaging. The only thing telling you what this product is is a sticker on the box. The syringes aren't labeled, there isn't an "ingredient list" type of thing inside the box. This doesn't really inspire confidence in the product. The instruction sheet provided is only for a light activated tray, so I had to do some additional research to make sure this would work in regular trays. Finally, the syringes don't move really smooth. You need to use a little pressure, and then Splat! A whole blob comes out at once. Luckily, they include a tiny brush, which I then used to spread the blob around the tray, and transfer some over to the other tray. This has happened both times. The taste is horrible, but I'm not faulting Dr. Song for this, since every bleach I've used tastes horrible.
