How Laser Teeth Whitening Works?

Laser teeth whitening works through a process that involves the application of a bleaching agent to the teeth, which is then activated by a laser. Here is a step-by-step overview of how the procedure typically works:


  • The dentist will first perform a thorough cleaning of your teeth to remove any plaque or tartar.
  • Your gums and lips will be protected using a rubber or plastic shield to prevent exposure to the bleaching agent.

Application of Bleaching Agent:

  • A whitening gel, usually containing hydrogen peroxide or carbamide peroxide, is applied to the surface of your teeth.

Laser Activation:

  • A specialized laser is directed at your teeth. The laser’s light energy activates the bleaching agent, which begins to break down the stains on the enamel and dentin layers of the teeth.
  • The laser enhances the effectiveness of the whitening gel, allowing for faster and more pronounced results.

Multiple Sessions:

  • The process may be repeated several times during the same visit, depending on the desired level of whitening and the initial color of your teeth.

Post-Treatment Care:

  • After the treatment, the dentist will remove the protective shields and clean any remaining gel from your teeth.
  • You may be advised to avoid certain foods and drinks that can stain your teeth for at least 24-48 hours post-treatment.


  • To maintain the results, follow good oral hygiene practices and consider touch-up treatments as needed.

    How Long Does Laser Teeth Whitening Last?

    The duration of laser teeth whitening results can vary depending on several factors, including your oral hygiene habits, diet, and lifestyle. Generally, the effects of laser teeth whitening can last anywhere from six months to two years. To maintain the results for as long as possible, it is important to:

    1: Practice good oral hygiene by brushing and flossing regularly.
    2: Avoid foods and beverages that can stain your teeth, such as coffee, tea, red wine, and tobacco.
    3: Schedule regular dental check-ups and cleanings.
    4: Consider using touch-up treatments or whitening toothpaste as recommended by your dentist.
