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.
How tooth shade is perceived is a matter that depends on complex interaction of several factors such as translucency, light scattering, opacity, lighting conditions, human eye and brain, and gloss. A human tooth is composed of several parts, but the color is determined by two main parts, that is, the enamel and dentin.
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.
A deciduous tooth is also generally whiter in comparison to an adult tooth. The same logic applies in that the ration of enamel to dentin varies. The tooth changes in its mineral structure causing it to become darker. Tooth wear may also cause thinning and/or perforation over time.
Tooth bleaching falls into two classes, that is, at-home and in-office treatments. In-office treatment is done by a dentist after a thorough examination of the mouth. The examination requires the dentist to obtain a dental and health history of the patient, including any sensitivities and allergies. Soft and hard tissues are observed as well as the condition of restorations. Irregularities may be determined better using x-rays.
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.
Several methods also exist for use at home, including paint-on films, whitening strips, rinses, and chewing gums. The effectiveness of these methods is not certain according to research findings. Also, these methods do not have any long term potential risks or effectiveness.
