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.
Complex interactions among various factors determine the perception of tooth shade. Some of the factors that interact include lighting conditions, translucency human eye and brain, opacity, gloss, and, light scattering. The enamel and dentin are the two components determining the color of tooth.
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.
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 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.
When bleaching, the bleaching agent, which could be hydrogen peroxide or carbide peroxide, is applied on teeth. Papilla, gums and other soft tissues are protected using light-cured protective layer. The process of bleaching is only effective on teeth that have turned yellow and not gray. The amount of time taken depends on the level of discoloration. Better results can be achieved using custom bleaching trays where ordinary bleaching proves to be ineffective.
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.
