This procedure, commonly known as tooth whitening, involves lightening the shade of the patient’s natural teeth. It is a very efficient technique for whitening the teeth and putting it back in its proper place. Each person may have a different tooth color. Tea, coffee, and cigarettes are examples of outside elements that stain our teeth. Since ancient times, bright, white teeth have been among the most desired components of an attractive smile. Therefore, you should visit your dentist if you believe that the color of your teeth has changed. The surface of the tooth is not abraded by this technique. There is no layer removed from its surface. Special substances are applied to the tooth surface to whiten it. Other tissues than the teeth are protected using isolation gels during the operation. A gel containing the active ingredient Hydrogen Peroxide or Carbamide Peroxide is administered to the tooth. Blue light is utilized to activate the product and enhance its impact.
