• Screening: The dentist conducts an initial screening to see if the gums have receded to expose the tooth root.
• Pre-Treatment: The pre- treatment is the preparation step and includes cleaning the teeth and ensure that all cavities are treated and filled before the bleaching process.
• Medication: Tooth whitening agent can cause temporary sensitivity. To avoid this, medications are prescribed prior to the first whitening session.
• The Whitening: The dentist begins the actual bleaching process by holding the mouth open with a plastic or rubber guard. A barrier gel is applied over the gums to protect them from the whitening agent. Next, the dentist uses a syringe to apply the whitening agent to the front of the teeth and uses a pen-style laser to activate the compound. From the energy of the laser beams the compound is activated and starts to foam and lifts the stains from the surface of the teeth. After all of the teeth have been treated with the whitening agent and laser beam, the dentist will allow the foam solution to remain for a few minutes. Later the foam is wiped off using a small vacuum tool. A new layer of compound is applied and the process is repeated as many as three times. After completing the bleaching process, the mouth is rinsed out gently and removes the protective layer from the gums.

After a laser teeth whitening session, there is an increased sensitivity for few days and medications are prescribed to avoid or reduce sensitivity. Follow up appointments are necessary to see the progress of the bleaching and it is highly recommended to avoid highly acidic food and beverages including tea, coffee and red wine to have long lasting results.
