Bleaching: It is a method by which the color of the yellow and badly colored teeth can return to normal or they can be more whitened than normal.
When it comes to teeth bleaching, you have three choices: bleaching at the dentist’s office, home bleaching, and combination of one or two sessions at the dentist’s office plus a complete home-based kit. In all the three methods, hydrogen peroxide based bleaching agents are used. The materials used in home bleaching contain peroxide 3% to 15% while peroxide 15% to 40% is used at the dentist’s office. The duration and method of use of each substance are different and specific. Substances are prescribed according to the conditions; increase and decrease in the duration and amount of the substance not only do not improve the results, but may also make the teeth more sensitive.
It should be noted that bleaching cannot whiten porcelain veneers or tooth-colored composites.
Bleaching at the dentist’s office: Bleaching done at the dentist’s office makes your teeth more whitened in a shorter period. Bleaching agents used by the dentist are more powerful than their home counterparts. In addition, heat and light, or the combination of both, may be used to accelerate and intensify the tooth whitening process. To achieve the best results at the dentist’s office, the teeth are 3 to 8 degrees whiter – about 60 to 90 minutes are required.
