Great product! Just don't use too much, it's very strong and will whiten your teeth in thirty minutes. This is my second time purchasing this product.

I'm going to make this short and sweet. You need a fitted mouthpiece for this stuff. It works 10X faster than the 20% stuff that I got from my dentist. And, I only use it for like an hour a day compared to the 20% which I used between 3 hours up to overnight. This stuff gives you very quick results and I would recommend it to everyone!!!

I have used the Opalescence whitening line for a few months. I used both 15% which I had to wear overnight and the 20% which is worn for an hour a day. I started using the 35% concentration because I really did not like wearing my dental trays overnight -- they hindered my sleep quite a bit. In addition, I liked the idea of only wearing the trays for 30 minutes each day (as opposed to the hour for the 20% concentration).
I have used the 35% for about a week and am seeing great results already. I really like the product but would mention a few precautions to those looking to try it:
(1) It will be pretty uncomfortable for someone with sensitive teeth. I notice some discomfort in my back teeth after removing the trays but it is usually gone by an hour or so. Sometimes the discomfort lasts longer but it is manageable.
(2) Using too much gel can cause your gums to burn. The instructions that came with my purchase failed to indicate how much gel was to be used during each bleaching session. I followed the instructions from my previous uses with the 15% and 20% concentrations, using a half of a syringe per treatment. This was too much. Despite having custom trays (which is a MUST with this system), the excess gel burned my gums in some places turning them white. The whiteness from the burn is gone in an hour and really is not uncomfortable but considering there was enough gel to reach the gums, it is pretty wasteful to use that much. Consequently, I now attempt to get 2.5-3 treatments per syringe. This has eliminated the potential for burning and reduced the discomfort associated with the high concentration. The bleaching process may take a little longer but it is worth it to alleviate these issues.
(3) I have had some uneven bleaching thus far. I have a few spots on my front teeth that are whiter than the rest of the tooth. From afar, this is not noticable but close up, it is obvious. I still have many treatments to go and am assuming it will all even out over time (it is already better now than it was 1-2 days after I started last week).
(4) Lastly, as I noted above, I would only recommend this treatment with custom molded trays. As I noted above, I have had some unevenness in my whitening thus far and cannot help but believe that this issue would be compounded if I did not have custom trays (and would be much harder to correct).
All in all, I am very pleased after a week of using this product. I gave it 4 stars only because I think the instructions should be more clear (i.e., how much gel is appropriate). I would recommend it to anyone looking for a great whitening product, excluding those with sensitive teeth.

I've just finished my first bleaching session with this product and, in all honesty, I have used whitening products from aquafresh, crest, colgate (including the version from colgate that dentist offices sell for bleaching), and two other versions of 35% Carbamide Peroxide solution...But Opalescence has been the best so far. The viscosity of the solution keeps the stuff in the mouth trays (mine are custom-made) better. I think anyone who bleaches their teeth will likely agree that the solution, the feel of the trays, and the occasional burning or stinging if there's too much product around one area of the gumline will make you salivate more than usual. (Duh!) Other products were notably thinned out or almost totally dissipated by the time I'd had the trays in for the recommended length of time for each. I would say there's an element of truth to assuming that, unless you can stop making saliva for 30 min. to an hour, having a 'thinner' solution that keeps seeping out of the trays (and thus the 'gel/spit' ratio decreases, spit being the victor) cuts down on the effectiveness of the treatment. A 'thicker' solution such as Opalescence pretty much didn't budge. I rinsed after the first time I used this product (which was, as I stated, just now and I was so impressed I leapt online-this is the first review I've ever written-it was THAT GOOD) a tactic which usually cleaned out most of the residue from the other bleaching gels I've used, and found that there was still a decent layer on my teeth for me to brush off. Yes the syringes are a little small and it's a little more expensive, but I'm no longer even interested in trying anything else. Opalescence will be the only bleaching product I buy from here on out. If you're on the fence about what brand to buy or whether you should bleach (though if you've never bleached before, perhaps try the lower percentage) I'd recommend this brand to anyone and it's absolutely worth a try.

I have tried several types of teeth whitening products. I really like this product because you only apply it to your teeth for 1/2 hour. Quick and I can see the results because of the 35 percent peroxide mix . . . much higher than other products used.
I recommend this product.
