Carbamide peroxide is an oxidizing agent that contains both hydrogen peroxide and urea. Many dentists use this with lasers to promote bleaching of your teeth. The hydrogen peroxide oxidizes stains on the tooth enamel. Many people use hydrogen peroxide to help whiten their teeth for several reasons:

• It promotes a healthier mouth
• No harmful acids or abrasives
• Ease in use
• Inexpensive

Hydrogen peroxide is used in a number of mouth and teeth rinses and pastes. In fact before many of the teethe whitening concoctions were developed, people used hydrogen peroxide and baking soda to brush their teeth. Both are excellent whiteners and a little table salt adds an extra exfoliant to the process. However since manufacturers have been producing teeth whiteners, there have been some rather remarkable results that have been obtained from using hydrogen peroxide as a whitener.

One particularly impressive tooth whitener that uses Carbamide peroxide is called Nite White ACP. This is a tooth desensitizer that uses a patented Amorphous Calcium Phosphate chemistry to bond with your tooth’s surface to fill any microscopic defect. This makes your teeth smoother and gives them luster. In addition to filling the microscopic defects in your teeth that make them so sensitive, most users have less fading of the white after six months of use of Nite White ACP. It comes in a three syringe pack that is good for 9-12 dual arch whitening sessions. It is used in an arch tray system and it is mixed by the syringe as it is placed in the trays.

Day White ACP is used just like the Nite White ACP but is designed to be used for less time. Where the Nite White ACP is only a 16% or 22% solution used for either 1 hour a day or overnight depending on which product, the Day White ACP is a 38% solution that is used for a period of only 15 minutes. It also comes in a three syringe pack that is enough for twelve dual arch trays and mixed by the syringe. These two whiteners are great for sensitive teeth because it helps fill in the small defects that make teeth sensitive while it whitens.

There are a large number of whiteners to choose from and many people must play a trial and error game before they find the whitener that works for their teeth. Since most people have different shades of white naturally on their teeth, it may take several uses before any difference is noticed. One should not judge a whitener by the effects of one application. You should use it a few times before switching to another whitener.
