What is the Recommended Carbamide Peroxide Level for a Whitening Gel?

After having done whitening for more than twenty years, here's what works best:


If you have sensitive teeth, De-sensitize first for two weeks. THEN start your whitening. We use a lot of prescription strength Fluoride gel in my office to accomplish this.

Find a time of day (or it's even OK to leave your trays in while you sleep) that you can do your whitening every day. 

EVERYBODY gets sensitive at some point, Skip a couple of days, but then get right back to it.

Sensitive patients should start at 10%. You may be able to work up to 16% later. If you start with too high of a percentage, you will be VERY sensitive and you will wind up stopping and not really accomplishing any real whitening.

Very good question. The answer depends on how fast you want to whiten and how sensitive your teeth are. 15-16% is fairly low and considered non prescription. You can get this same percentage from a number of reputable manufacturers. Some people are mixing up whiteners in their bathtubs and selling them online to unsuspecting consumers. Be careful to purchase whitening gel from reputable sources. Especially when online.
