Opalescence Tres White Supreme Pre Filled Whitening Trays

I wasn't too happy about using pre-filled trays, but I gave them a try anyway. I was totally amazed at the results. Now I admitt that I may have allowed the product to stay on longer than necessary; some sensitivity did occur. Leave on about an 20 minutes to an hour; NO LONGER. Hydrogen peroxide doesn't need to stay on as long as hydrogen carbamide. Unless one's teeth are totally "JACKED UP", two or three sections will prove to be enough. Save the rest for later dates.This product is much, much, cheaper than a dentist's treatment, and one can control their level of brightness. Give it a try for yourself. This is an unbias report, I'm not getting paid for these comments; which is too bad.

This product really made my teeth white after just 1 use! I used whitening strips before but it took at least a week before I was happy with the results. I got the Tres White because my dentist recommends Opalescence, but I didn't want to pay for whitening trays. It's a little more expensive than the whitening strips you find in drugstores but you'll definitely see results sooner. Oh and I didn't experience any sensitivity with these either.

I purchased these about a month ago and I thought I would just share my opinion with everyone out there just in case you are in the market for some teeth whitening products. Now I don't know how helpful my review will be since this has been the only teeth whitening product I have ever tried, but I guess it doesn't hurt to share my experience. First off I just want to give everyone a little background, I am in my 40's and drink coffee on a daily basis and drink soda a few times a week as well. Overall my teeth are pretty stained from the years of poor maintenance. I wouldn't say they are horrible but on a scale of 1 to 10 they are at a 5. After looking at some pictures of myself I noticed my teeth were pretty yellow and dull. So I went online and purchased this product, I purchased this product because I do not have whitening trays and these looked like they would work. After just using it for 2 days (2 applications) I already was receiving a few compliments. After using the products for 2 weeks and going through 7 applications I noticed a day and night difference in how white my teeth were. I honestly did not know it was this easy to get white teeth. Now I would say my teeth are at an 9 out of 10 in how white they are and I still have 3 applications left. Now just a side note to everyone, I used this product every other day because my teeth did get a little sensitive after each use. It wasn't anything to bad, but it was noticeable so I decided to break it up by whitening them every other day allowing them to get a break. Overall I am so happy that I have white teeth now and it only took 2 weeks and cost less then $50.
