5 XL 38% Teeth Whitening Gel Dentist Recommended High Intensity Carbamide Peroxide Pro Dental Lab Direct, Sensitivity Free, Sold by Dentists, Whiter Smile Labs Fast WHITENING Results

I’ve only used this once for about 20 minutes with a blue light bc I happen to have one but I’m not new to teeth whitening. I’ve been doing it off & on for years & I can already tell this is a great product. I drink coffee daily & love teeth staining foods like blueberries. So I have to whiten regularly.I’ve had trays made from a mold of my teeth. You can find this online - they send you the mix & basic upper & lower treys to make your impression (just like they do in the dentist’s office - I used to be a dental assistant) . You send that mold back. They then make upper & lower treys of the mold & send them to u. These are the best to use bc they fit perfectly so they’re very comfortable & u don’t waste any whitening product. But I previously used a 35% carbamide gel (for which I paid more) & I can already see that this works better. Absolutely no irritation at all which is amazing bc I do brush with Sensodyne or Pronamal daily for my typically sensitive teeth. So that’s a HUGE bonus for me.Also, you will easily get 3 treatments out of each syringe. You don’t want to overload the tray bc it will just spill over into your mouth when you insert them which wastes product.I keep these in my fridge as the manufacturer suggests.You’ll be pleased with this product. I hope this review helps.

I have used this product before and it works well, but it takes time. I can't use anything with mint flavor, so my options are quite limited, and I am pleased with the results of this product. I used this product with the trays for about two or three weeks, every other day for about thirty to forty minutes to get the results I wanted. It takes a very small amount for each tooth placed in the trays, so the five vials should last through an entire treatment, with possibly some left over. I stored any excess and new vials in the fridge.I experienced a slight sensitivity using it two days in a row, so I started using it every other day and had no sensitivity issues.

It whitens well, it creates a little sensitivity but not bad, just can't use it multiple days in a row. The problem is that the liquid in the syringes broke down quickly, turning from a gel to a liquid within a couple of months, which made it pretty useless. I ended up throwing half of them away. I tried refrigerating them, but that didn't make a difference. Next time I'll order just a few syringes at a time rather than a huge batch.

First I will say that this is the first serious DIY tooth whitening product I have tried. I have never noticed a difference with the various whitening toothpastes, so figured, I needed something more professional. I made my decision based on origin of product, customer reviews and price. This product is near the maximum strength ever approved by the ADA. I have a lot of fillings which is a concern. I also have a little bit of gum recession, so didn't want to use something too strong, which may cause unwanted effects or necessitate another purchase of anti-sensitivity gel. I don't know why some report this product didn't whiten their teeth. I just completed my first application, and see a significant improvement - moreso than after a teeth cleaning session I recently had at my dentist. You can tell the product is working because it foams a little bit as the hydrogen and oxygen escapes. I only used about 3/4 cc, so these 5 syringes will probably provide 20 whitening sessions, but I was careful to apply the gel only to the front of my trays. I used this gel in combination with the Whiter Smile Teeth Whitening trays, because they appear to be made in the USA and are BPA free. I will provide a separate review for them. I do not trust Chinese health products, which was a positive influence for this purchase. I cannot say whether a stronger formulation would work better for me, but I can say I think this is a good product, which works well, so I can fully recommend this whitening gel. If I experience any undesirable effects I will amend this review.

I HESITANTLY purchased this product a few weeks ago. I normally whiten with Nite White purchased from my dentist or Crest Premium Whitening Strips, but I'm a product junkie and purchased this due to the 38% peroxide. The first two uses were extremely painful. Possibly, I used too much but I'm not sure. The syringe was difficult to use and I had to remove the top portion which caused the gel to come out in large amounts. Overall I am satified because I have noticed a change in my teeth after the first three usages. My teeth are pretty white so I am not sure how many more shades they can be improved, but I will keep you all posted.SIDENOTE: The package came with a guide on liking the product page on facebook and a website that is not existent. This was a little scary for me! Just wanted to share!
