I ordered these gels to go with the trays I already had from my dentist and they work very well. The price is a fraction of what the dentist charges and they are delivered right to my door within a few days. I can see the results and love having extra gels on hand just in case i need a touch up.

I've only used it a few times but seems to do a good job.

I order de product thinking that it would be like the dentist givse to whitening the teeth from home. The results were not has obvious as the one from the dentist. I end up not using it and made my teeth sensitive. My teeth are pretty white, I only want the product as maintanance but did not notice much difference. If you want serious results I do not recommend this specific product.

I should have paid attention to the other reviews - the product didn't whiten my teeth at all. I suspect it is outdated or of much weaker strength than stated. I would not recommend this to anyone!

This is a great product - it's strong stuff, and works quickly. I have used a number of teeth-whitening products in the trays I got from my dentist, and this is a very good bleach.

This product is very good, only a small amount is necessary. To much can hurt your gums as the bleaching agent is strong. The mineral gel is worth the extra cost. Overall cost is very good. Results are very fast, usually after the first application. Recommend for adult use only.

I have used 32% whitening gel from my dentist before and I don't think this is really 35%. With my dentist's gel if I left it on more than 30 minutes, my gums would get sensitive but I can leave this on for hours without any problem. Also unlike my dentist's get, there is no foaming and hardly any peroxide taste . I have been using it for 2 weeks and see absolutely no improvements. Maybe I just got old gel, but I won't be buying this again!

I have trays for my teeth for whitening and I do it on a regular basis. This whitening is a great product with heavy strength. It takes a shorter time and quicker results. Follow the instructions and do no leave on more then a few hours at most. Also because of the strength I give a few days in between if I want to do for a few times so your gums do not get sensitive.Highly recommend.

Great product...be careful not to use too much at first. Gradually increase the usage time. Whitening lasts much longer than other over the counter products I have tried.

Far superior to retail whiteners. Far less expensive than my dentist's. The gel needed to be refreshed with water (explained how in the instructions sheet). That was a bit annoying, but the results are great. I'll buy again next year.

Very minimal results from this product. Horrible taste and thickened in syringe. It's too much of a time and effort investment for the results. I doubt it's really 35%. After two applications in one day my teeth weren't even a little sensitive which is a good way to judge the strength. I'm going back to the 20% I used before.

The whitening product seemed to work well after numerous applications. Much better value than a dentist. Still trying to get as white as the dentists system but they are noticable whiter and I have used the 5% products before. Not completely convenced of the sensitivity gel, but I don't believe it can hurt and for the price it's a great buy overall.

This product has exceeded my expectations. The stronger gels work much faster and they are 3 times as big as the gels from the dentist. The free sensitivity gels are a bonus. Will be back to buy more... Thank you Overstock

The product doesn't work & didn't whiten my teeth at all!

I was pleasantly surprised not to feel any gum irritation despite using the product 3 times on the same day for 45 minutes each time. I noticed a slight brightening effect, less than expected. (My teeth are not stained but rather yellowish from age.) I'll keep using the product until both syringes are empty. The application was extremely easy and not messy at all.

This stuff really works. it was quite noticeable right away. Will definitely buy it again.

Worked pretty good. I still like the kind I get from my dentist better, but for convienance, this is fine.

since i smoke and practically live off coffee, my teeth tend to discolor regardless of how often i brush. i already had a tray, so it was nice just to be able to purchase the refills and not the whole kit. i only used the whitner, not the finishing gel that comes with it. after four nights using it for 2 hrs per night, i noticed a difference. not dramatic, but definitely helped reduce the yellowing stains. i'm hoping a few more nights and i'll be happy with the results. as long as your expectations are reasonable, and you're willing to put in the time, than it's worth it.... just don't expect miracles after one application.

Excellent product- will order again. Very easy to use.
