The process of teeth whitening refers to the restoration of tooth shade to the natural color or bleaching beyond the natural color shade. When restoring the color of tooth, calculus and surface stains have to be removed. Stains result from food and other substances that people consume. Common sources of stains include coffee, tea, tobacco, and wine. The process can be done at home by oneself or in a dentist office. For professional teeth whitening Houston offers the best location one should pay a visit to.
The perception of tooth shade is determined by a complex interaction of many factors, which include translucency, lighting conditions, light scattering, human eye and brain, gloss, and opacity. The two parts of the human tooth that determine its color are 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 emergence of better technologies replaced the use of light accelerated bleaching. Light accelerated involves the use of light energy to accelerate the rate at which bleaching occurs. Various kinds of lights can be used for the acceleration. Some of the most common ones are plasma arc, halogen, and LED. These methods may cause sensitivity of teeth. They may also not be effective if only small amounts of bleaching agents are used.
There are many methods that one can also use to whiten. The major ones are paint-on films, rinses, chewing gums, and whitening strips. However, research indicates that the effectiveness of these methods is questionable. There is also no potential risks or effectiveness associated with the methods.
