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.
The perception of tooth shade is determined by a complex interaction of many factors, which include translucency, lighting conditions, light scattering, human eye and brain, gloss, and opacity. The two parts of the human tooth that determine its color are the enamel and dentin.
Enamels are usually transparent and whiter in color while dentins are less transparent and darker. Compared to bones, these parts are more calcified. Therefore, a tooth is not colored like pure white, but instead it is bone-colored. Males also have darker teeth than their female counterparts. This is because a female tooth is smaller, with smaller dentin and bigger enamel. Molars, which are larger in size also appear darker.
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.
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.
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.
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.
There are many methods that one can also use to whiten. The major ones are paint-on films, rinses, chewing gums, and whitening strips. However, research indicates that the effectiveness of these methods is questionable. There is also no potential risks or effectiveness associated with the methods.
