Nite White Excel 3 ACP Z 22% Teeth Whitening 6pk Kit (Packaging may Vary)

Although my teeth were pretty white to begin with, I thought I would give them a try because of some soft coffee staining. Teeth were clearly whiter after the first use. I used them in a custom tray overnight. After two nights of use my teeth were a little sensitive so I then used them every other night and I had no other problems. I have only used them for about five nights total because I don't think my teeth can get any whiter for the time being. I would suggest using a sensodyne or other desensitizing toothpaste a week or two before starting to use this if you have any sensitivity issues. I would suggest wearing this solution for at least four hours a day for the best results from all of the research I have done on the different concentrations. If you are truly afraid of sensitivity the 10% and 15% carbamide peroxide will get you the same results as this 22%, but it may take a little longer! Definitely worth the price...I love this stuff. People were saying how white my teeth were literally one day after using it.

This product is the same as my dentist sold me, but I got double the product for the same price. I had made a mistake and bought the "limited free trial" of other products, only to find you have to send them back for a partial refund or you are locked into paying/receiving products for a long time and much more cost then this product. Stay away from them, as they are rip-offs. However, this product is the real thing! It works! Yes, sensitive teeth folks, it will be uncomfortable at times, but you just take the trays off sooner. I have found I had to give up coffee completely in order to keep my teeth white, but I decided it is worth it. This product works, and you don't have to keep smiling for 15 minutes hoping it will work. You just put a small amount, as per the directions, into the trays; put the trays on your teeth, and 1-2 hours latter you have noticeably white teeth!

I purchased the NiteWhite ACP 22% 6 pk kit from Direct Super Center (DAB Nutrition)because it was fulfilled by Amazon.com and it was eligible for free super saver shipping. It arrived in a timely manner within a week.I have been using NiteWhite for more than 10 years. I have custom trays from the dentist. I'm familiar with the product. The kit I received from Direct Super Center/Amazon.com is the NiteWhite ACP The Standard Kit - 6 (2.4ml ea) syringes, instruction book, container to put your trays. The label on the box with Exp Date of 6/2011 and lot #. I would have preferred a Exp date closer to 18 months, but no prob, I am splitting the kit with my sister. And it still gives me 10 months to use the product before Exp. date. The box came shrink wrapped.The price was very good but if had waited a few more days, the price would have been even better since it is even cheaper now. But still far cheaper than a dentist.

Great whitening gel. This is the authenticate genuine kind of whitening gel you want to use in your trays to bleach you teeth. I am very happy with this product except for the experiation date is always 6 months close from the time i receive them. Meaning i have to use the item within 6 months. I feel they should send me ones that dont expired for at least a year as that what i have read from others. I will be switching brand if it happens one more time.

It is strong and does exactly like they say.If you have bought this, it is strong and you need to follow the directions. DO NOT think longer is better like some people on line have done and leave it on for more than the recommended time. I tried leaving it on for 3.5 hours and it made my gums raw. I had to deal with the pain for several days. It was MY FAULT for listening to others on the Internet saying they left the 22% on overnight. I'm so thankful I wore mine during the day because if I had gone to sleep with it on I would have really been in a mess. I took it off when it started to hurt.My failure to follow directions and the results were MY FAULT and not the fault of the product. It is a great product.

This product whitens your teeth well when used in custom trays according to directions. After three days in a row of use you end up with sore spots on your gums, so be careful with how often you use it.

This product DOES work. However, I believe what they send you is an EXPIRED 22% Nite White (not excel 3) product. It does not come in the Excel 3 pack. So DO NOT expect it to work if you only use it for an hour a day. I used it overnight (usually 6 hours). I am still using it, but I only applied 2 syringes so far and I CAN see a difference. I do not recommend you use your invisilign retainers to hold the gel unless you have been wearing them often enough that it no longer hurts your teeth. I bought a mouth guard to hold the gel, it works fine. Before you sleep make sure there is no - limited amount of gel touching your gums. Sensitivity of the teeth may occur. Skip a day or two if your teeth/gums begin to hurt. Shipping is quick/on time. No damage to the products. Directions are on the back of the label covering the syringe container.
