How Does Laser Teeth Whitening Work? A Step-by-Step Guide

Laser teeth whitening is a popular cosmetic dental procedure that can dramatically transform the color of your teeth, leaving you with a brighter, more radiant smile. If you’re considering this treatment, it’s essential to understand how the process works. In this step-by-step guide, we’ll walk you through the procedure of laser teeth whitening brisbane.

Step 1: Preparation

Initial Examination

The process begins with an initial examination by your dentist Ashgrove to assess your oral health and determine if you are a suitable candidate for laser teeth whitening. They will check for any existing dental issues that may need to be addressed before the procedure.

Step 2: Cleaning

Professional Cleaning

Before the whitening process begins, your dentist or dental hygienist will clean your teeth to remove any plaque, tartar, or surface stains. This ensures that the whitening gel can make direct contact with your tooth enamel for optimal results.

Step 3: Shade Selection

Choosing the Right Shade

Your dentist will use a shade guide to determine your current tooth color and identify the target shade for the whitening treatment. This step helps in setting realistic expectations for the outcome of the procedure.

Step 4: Application of the Whitening Gel

Protecting Gums and Lips

To protect your gums and lips from the whitening gel and laser, your dentist will place a rubber dam or a protective barrier over them. This isolation technique ensures that only your teeth are exposed to the whitening treatment.

Application of Whitening Gel

A highly concentrated hydrogen peroxide or carbamide peroxide gel is applied to the surfaces of your teeth. This gel acts as a bleaching agent and penetrates the enamel to break down and remove stains and discoloration.

Step 5: Laser Activation

Laser Exposure

A specialized dental laser is used to activate the whitening gel. The laser emits a focused beam of light that accelerates the whitening process, making it more efficient. The heat from the laser helps to activate the gel and enhance its effectiveness in breaking down stains.

Step 6: Multiple Sessions

Reapplication and Laser Exposure

The whitening gel may be reapplied and exposed to the laser multiple times during the same session. This process is repeated until the desired level of whitening is achieved.

Step 7: Post-Whitening Evaluation

Shade Comparison

Once the desired level of whitening is achieved, your dentist will compare the post-treatment shade of your teeth to the initial shade recorded at the beginning of the procedure. This allows them to assess the effectiveness of the treatment.

Step 8: Aftercare Instructions

Post-Treatment Care

Your dentist will provide you with aftercare instructions, including dietary recommendations to avoid staining foods and beverages immediately after the procedure. They may also recommend fluoride treatment to reduce tooth sensitivity.

Step 9: Follow-Up Appointments

Monitoring and Touch-Ups

Your dentist may schedule follow-up appointments to monitor the long-term results and provide touch-up treatments as needed. Regular dental check-ups and good oral hygiene are essential for maintaining the whiteness of your teeth.


Laser teeth whitening is a highly effective and efficient way to achieve a brighter smile. Understanding the step-by-step process can help you feel more informed and comfortable if you decide to undergo this cosmetic dental procedure.
