The laser teeth whitening applied at Sonrisa Perfecta Dental clinic is a technology that has been used since the 1960s. It was around 60 years ago that the first dental treatments using lasers as one of their essential components were introduced.
In recent times, this treatment has gained much popularity due to its effectiveness, safety, and speed of results. The evolution of the instruments used for its application, as well as the development of more advanced gel formulas, have contributed to the increase in demand. What are the steps involved?
What is laser teeth whitening?
Laser teeth whitening is a cosmetic treatment in which a whitening gel with agents such as hydrogen peroxide is applied to the surface of the teeth and then activated with a laser beam to accelerate stain removal. It also aims to give the tooth enamel the most suitable natural white shade for the patient. This procedure, performed by a dentist, aims to offer fast and visible results in one or a few sessions. Each session lasts between 45 and 90 minutes, depending on the patient’s needs. A laser teeth whitening procedure (or photoactivation) is performed in the dental office and generally follows these main steps.
Step-by-Step Laser Teeth Whitening
- Preparation
Before whitening, the dentist performs a thorough evaluation:
Medical History and Oral Examination: Oral health is reviewed, and any cavities, leaking restorations, or sensitivity are detected. The patient is informed that existing restorations (fillings, crowns) will not change color.
Prophylaxis (Professional Dental Cleaning): This step is essential. A cleaning is performed to remove all plaque, tartar, and external stains (exogenous pigments) that could reduce the effectiveness of the whitening agent.
Shade Determination: The initial tooth color is documented using a shade guide (VITA scale) or a colorimeter. Photographs are often taken for before-and-after comparison.
Expectation Management: Possible results are discussed with the patient to establish realistic expectations.
- Isolation and Protection
Whitening requires protecting the soft tissues (gums, lips, and mucous membranes) from the action of the whitening gel.
Placement of Protective Measures: Lip retractors are placed to fully expose the teeth.
Gingival Barrier: A protective gel or gum barrier is applied to the gums. This material polymerizes (hardens) with a special light, sealing and protecting the gums from any contact with the peroxide. - Application of the Whitening Gel
Gel Application: The dentist carefully applies the whitening gel (usually hydrogen peroxide or carbamide peroxide based in high concentration). It is applied directly to the visible surface of the teeth to be whitened. - Laser Activation (or LED Light)
Photoactivation: A laser or a specific cold light (LED) lamp is used to emit light onto the gel. The light energy is absorbed by the gel, accelerating the release of oxygen molecules.
The Process: These molecules penetrate the enamel and dentin, breaking down the pigments that cause discoloration, thus achieving the whitening effect.
Application Cycles: The light and gel application process is performed in several cycles. For example, 2-4 cycles of 10 to 15 minutes each, until the desired result is achieved. After each cycle, the gel is removed and a fresh layer is applied.
- Finishing and Enamel Protection
Once the whitening cycles are complete:
Gel and Barrier Removal: The whitening gel and the protective barrier are carefully suctioned away from the gums.
Rinse: The patient rinses their mouth.
Fluoride/Desensitizing Application: A fluoride gel or a special desensitizing agent (amorphous calcium phosphate, ACP) is applied to seal the enamel pores. This helps reduce post-treatment sensitivity.
- Results and Recommendations
Final Evaluation: The new tooth color is compared to the initial color to verify the results.
Post-Treatment Instructions: The patient is given instructions to follow, the most important being the «white diet.» This consists of avoiding highly pigmented foods and beverages such as coffee, tea, red wine, dark sauces, and tobacco. This dietary regimen should be maintained for at least the first 24 to 48 hours.
