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.
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.
The enamel is whiter and semitransparent while the dentin is darker and not as transparent. These two parts are more calcified compared to bones. As such, the color of the tooth is not pure white, but rather, it is bone-colored. Naturally, females tend to have whiter teeth than males. This can be attributed to smaller tooth size, which reveal smaller dentin layers. Similarly, larger teeth such as molars tend to be darker in color.
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.
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.
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.
