Teeth whitening is also called tooth bleaching. It is the process of restoring teeth color to the natural tooth shade or bleaching the color beyond the natural shade. Restoring the natural color of tooth involves removing the surface stains and calculus. The stains are caused by substances people consume such as tobacco, coffee, and red wine. The process is can be done by a dental professional in a dental clinic or at home using oral hygiene techniques. For the best teeth whitening Houston is the place to go.
Complex interactions among various factors determine the perception of tooth shade. Some of the factors that interact include lighting conditions, translucency human eye and brain, opacity, gloss, and, light scattering. The enamel and dentin are the two components determining the color of tooth.
Enamels have whiter shades and are semitransparent while dentins are darker and less transparent. Enamels and dentins are more calcified than bones. As such, a tooth is colored more like bones than pure white. Female tooth is usually whiter compared to that of males. This is caused by smaller dentins and larger enamels in female tooth. Molars are also bigger in size hence are darker than incisors and canines.
Deciduous tooth is also whiter in color when compared to adult tooth. The cause of the color variation is presence of larger dentins than enamels. The difference is further contributed to by changes in mineral structure. Teeth get perforated and thinning occurs with time due to tooth wear and tear.
Tooth bleaching is placed into two categories, in-office and at-home treatments. Dentists usually do in-office treatment after they first examine the mouth thoroughly. While examining the patient, the dentist notes any allergic reactions and sensitivities the patient may have. They also take a health history as well as a dental history. The status of restorations is noted and observation of hard and soft tissues is done too. X-ray and imaging methods may also be used.
Some of the bleaching agents used include carbide and hydrogen peroxides. These agents are applied to the teeth while protecting soft tissues such as gums and papilla using a protective layer cured by light. Teeth that are yellow in color are bleached in a better way than those which are gray. How long the process takes depends on the level to which discoloration has occurred. Custom bleaching trays are better at bleaching than ordinary bleaching.
The use of light accelerated bleaching is no longer in wide use as better technologies have come up. In this process, light energy is used to make the bleaching process to occur at a faster rate. Although various types of lights can be used to accelerate the bleaching, the most commonly used ones are plasma arc, LED, and halogen. The disadvantages of these lights is that they may increase sensitivity of tooth and may not be effective is the amounts of bleaching agent used are small.
Methods for bleaching are very many. Some of the main ones include rinses, chewing gums, whitening strips, and paint-on films. The level of effectiveness of the various methods has always been questioned. No potential risks have been associated with the method just as long term effectiveness is not guaranteed.
