5 XL 38% Teeth Whitening Gel Syringes Dentist Recommended High Intensity Carbamide Peroxide, Sensitivity Free, Sold by Dentists, Whiter Smile Labs

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 done a lot of research on teeth whitening gels. I went to my dentist and was recommended to visit this company, I normally purchase from him for a lot more money, but was on a tight budget this month, I have been seeing him for 10 years now, and he does his best to help save me money, he said that they sell the same products with same quality , but direct to public. He was right. I used the gel for the first time last night and after 20 min, I saw a difference right away. And after the second use my neighbors complimented me on my whiter teeth (quit smoking 4 months ago) without me telling them I started a 7 day whitening cycle. I previously ordered some other kinds that were much cheaper, but did not experience anything but gum irritations and sensitivity. Now I know why the price was so low. This gel did NOT give any gum irritation or sensitivity. Overall I give this product a 5 star all around, and it came packaged real nice, so no one could tamper with it. and had instructions and tips for proper use. The gel also came with a dispensing tip that is far better than any other kind I used.. it is a metal tip that screws on the end of the syringe (not the cheap plastic kind) and allows you to guide the gel and apply the proper amount. It really takes the guess work out of how much gel to apply. I will buy again and also recommend to others.

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!

I've whitened my teeth at home and professionally and for me at least, this was the best by a wide margin. Here's why: - Speed. My coffee and wine stained teeth were whiter on day two. By day 7 a friend said, "that's enough!" and kept me from going too white. - Cost. This was among the least I'd spent on whitening and worked the best. Value? It's through the roof. I still have 3 1/2 tubes in the refrigerator. - Simplicity. Note: ** I have and used custom made trays from my dentist** I filled my trays as per the instructions and went about my business. - No burning or sensitivity. I've 'burned' my gums before, but not using these. I could tell there was a little sensitivity, but not enough that it was painful, only enough that I knew it was there. A nothing for me. Everyone's teeth might react differently but here's what I did each day. 1. Flossed and brushed my teeth. 2. Filled the upper and lower trays. 3. Dried my teeth with a paper towel. Useless? Maybe, but it's what I did. 4. Rubbed some in between my teeth with a Q-tip 5. Put the trays on 6. Left them on for 30-40 minutes. 7. Took them out and then rinsed. This product worked so well for me. I am amazed and happy with the results.

total waste of money. I already have pretty teeth and I get complemented on my teeth and smile often(all thanks to God & my parents)... but sometimes it is nice to have a hint of a brighter/whiter smile... I bought this because it says its dentist grade and it doesnt hurt or irritate... wrong. not working well, and it is messy, and it is painful, and not just when it is on, but well after... my teeth are more sensitive to cold and even just breathing in air at night if my nose is stuffy... just not a great buy. thanks, but no thanks.

I have tried various types of products including strips and gels purchased at retail drug stores. This by far beats all products I have used up to date. My teeth are sensitive to normal hydrogen peroxide rinse so I was looking for a product that didn't irritate. This product was shipped normal mail and took a little longer that my normal Amazon orders but it arrived by date promised. The product arrived and looked exactly as described. I followed the directions for first time use to test for sensitivity and used in a "tray" that I had left over by a previous product. It was not a custom made tray that would probably help with better results. I only left gel in for 15 minutes, and I am sure some got onto my gums but when I took the tray out and gave a quick rinse I noticed IMMEDIATE results. I would say that using one application, (about 1/3 of one syringe) gave me the same results as using Crest strips for several days. The next application I left on for about 30 minutes, thinking that this would probably irritate for sure but I had none! So far I have used only 1 1/2 tubes and have great results and that made this an even better value. I am not sure what the results would be by just placing drops onto teeth. The taste was fairly neutral so the whole experience was pleasant. I will recommend this product to anyone and it was worth the little longer delivery time.
