What is teeth whitening? What are the techniques? Are there teeth whitening methods that can be done at home?
Teeth whitening is simply a process that eliminates discoloration and stains on the teeth. The procedure also brightens the natural pigmentation of the teeth. The nature of the stains as well as the severity of the discoloration determines the degree of improvement after the treatment.
When your teeth become brown or yellow due to coffee, tea, or smoking, stains will generally lighten four to five shades. Gray teeth caused by natural pigmentation or use of antibiotics will lighten two to three shades.
