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.
