Most whiteners use a peroxide-based chemistry. Peroxide compounds have the ability to whiten teeth through an oxidation process. It has been demonstrated that peroxide has the ability to penetrate the inner aspect of the enamel within a matter of only a few minutes after application. There are complex organic molecules within the tooth that reflect a specific wavelength of light and are responsible for the color. It is believed that by releasing free radicals, peroxide has the ability to oxidize the color-producing organic compounds found within the enamel’s matrix. When these organic compounds are oxidized, the residual molecules reflect less light, or can also be described as colorless, thereby creating a reduction or elimination of the discoloration — whiter teeth!

Dental bleaching, also known as tooth whitening, is a common procedure in general dentistry but most especially in the field of cosmetic dentistry Whitening is not a one-time procedure. It will need to be repeated from time to time if you want to maintain the brighter color. What It's Used For The outer layer of a tooth is called the . The color of natural teeth is created by the reflection and scattering of light off the enamel, combined with the color of the under it. Your genes affect the thickness and smoothness of the enamel. Thinner enamel allows more of the color of the dentin to show through. Having smoother or rougher enamel also affects the reflection of light and therefore the color. Every day, a thin coating (pellicle) forms on the enamel and picks up stains. Tooth enamel also contains pores that can hold stains. The most common reasons for teeth to get yellow or stained are: Using tobaccoDrinking dark-colored liquids such as coffee, cola, tea and red wineNot taking good care of your teethAging also makes teeth less bright as the enamel gets thinner and the dentin becomes darker. It is also possible to have stains inside the tooth. These are called intrinsic stains. For example, intrinsic stains can be caused by exposure to too much as a child while teeth are developing. Other causes include antibiotics. They can stain a child's teeth if taken by a mother during the second half of pregnancy or by a child who is 8 years old or younger. Teeth are still developing during these years. Trauma may also darken a tooth. Tooth whitening is most effective on surface (extrinsic) stains. Preparation Other dental problems can affect the success of tooth whitening. For example, cavities need to be treated before teeth are whitened.

Laser Teeth whitening can be performed with or without light technology. Light technology is referred to as photopolymerization and was first approved by the FDA for teeth whitening in 1996. There are two light techniques that can be used: blue-light or argon laser light. Both techniques require about one hour in the dental chair. Application of a high concentration hydrogen peroxide is applied to the tooth surface four times at 15-minute intervals. Both light systems claim to work by accelerating the chemical reaction. This provides faster, more effective results. There are some concerns associated with the light generating heat and the possible adverse effect it may have on the teeth. Additionally, recent debate has spurred further examination in the dental community about how necessary the light actually is in the process. Power whitening without light technology simply uses an in-office application of a high concentration of hydrogen peroxide to jump-start the process. Both techniques (with or without light technology) will usually include an at-home whitening process involving custom trays made by a dental professional. A whitening agent is placed in the trays and they are worn usually once a day for up to three hours. The length of time worn and duration is determined on factors considered by you and your dentist. Custom trays are made to continue the whitening process at home and ensure you achieve optimum whitening results. The primary benefit of power whitening is that the process takes only one in-office visit and results can be dramatic and almost immediate. The disadvantages include cost. Power whitening is significantly more costly than other methods. You are paying for the technology, professional application and guidance along with the convenience of fast results.
