The process by which the natural color of tooth is recovered is called tooth whitening or tooth bleaching. Sometimes the bleaching may be intended to achieve whiter tooth beyond the natural color. The process involves removing calculus and other stains formed on the tooth. Coffee, tobacco, tea, among other substances are the causes of the stains. One can perform the process at home or they can visit a dentist at a dental office to have it done. When in need of professional teeth whitening Houston should be the first place to visit.
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.
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 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.
The bleaching process involves application of either carbide peroxide or hydrogen peroxide on teeth. Light-cured protective layer is applied on the papilla and gums to prevent damage being done on soft tissues. Bleaching is effective on yellow-colored teeth as opposed to gray ones. The process varies in time depending on how discolored the teeth were. If the results of bleaching are not effective, custom bleaching trays may be used to achieve better results.
Light accelerated bleaching is less common these days because better technologies have replaced it. Light accelerated bleaching as suggested by the name employs light energy to make bleaching occur faster. LED, plasma arc, and halogen are examples of light energy used. This method requires the use of large amount of bleaching agents to achieve the best results.
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.
