Teeth bleaching on a simple scale is the treatment of teeth using an oxidizing or bleaching agent to lessen or eliminate stains by lightening the discolouration of the enamel of the teeth. Causes of teeth discolouration can be due to aging, consumption of staining substances such as coffee, tea, smoking, trauma and nerve degeneration. Professional dental treatment is strongly encouraged. Tooth bleaching may lead to increase in tooth and gum sensitivity to coldness during treatment.
