Teeth whitening is one of the most opted cosmetic treatment in dentistry. The latest advancement in this procedure is the use of Laser for teeth whitening. It is also the most expensive form of teeth whitening treatment.

How does LASER work in Teeth Whitening?

Why Laser Teeth Whitening?

In order to avoid the following changes in the teeth surface:

  • Traditional teeth whitening techniques causes changes in the hardness of the enamel.
  • Subsequently, a reduction in the fracture toughness of the tooth surface.
  • It can cause tooth surface loss.
  • Also weakening the microscopic structure of the mineral content of the teeth.
  • Finally, to gain more whiteness of the teeth.

Steps in Laser Teeth Whitening:

  • Firstly, a complete professional dental cleaning along with an assessment of already filled teeth and filling of any new decay for a complete seal.
  • A pre-procedural medication to help them overcome the mild sensitivity usually felt after the treatment.
  • The dentist places a rubber barrier to separate and secure the oral tissues.
  • Then a gum barrier gel is applied on the entire gum surface to protect it from the bleaching gel.
  • The bleaching gel is completely applied to the tooth surface.
  • Finally, a pen styled laser helps in activating the gel for teeth whitening.
  • After a few minutes, the gel is removed with a vacuum suction tool and rinsed off with water. Cover the other surfaces with the same procedure.
