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.
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.
Tooth bleaching is placed into two categories, in-office and at-home treatments. Dentists usually do in-office treatment after they first examine the mouth thoroughly. While examining the patient, the dentist notes any allergic reactions and sensitivities the patient may have. They also take a health history as well as a dental history. The status of restorations is noted and observation of hard and soft tissues is done too. X-ray and imaging methods may also be used.
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.
