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.
The color of deciduous tooth is usually white compared to those of adults. What causes the different is the ration of enamel to dentin, with the later having more enamel and less dentin. Change in mineral structure also contributes to the difference. Over time, perforation and/or thinning occurs as a result of tooth wear.
The process of tooth bleaching can be classified into in-office and at-home treatment. In-office treatment starts with an examination of the tooth by the dentist. As they perform the examination, they may take health and dental history, including sensitivities and allergies. They observe soft and hard tissues, and the condition of restorations. Sometimes they may use x-rays in determining irregularities within the mouth.
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.
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.
