The Science Behind Professional Teeth Whitening
Teeth whitening procedures use chemical processes to lighten the color of teeth. These treatments target molecular compounds that have discolored the tooth structure over time. Understanding the science behind these methods provides clarity on how professional whitening works, revealing the scientific principles that make the process effective. Here is more information about teeth whitening technology:
Medical-grade Whitening Solutions
Professional whitening formulations may use hydrogen peroxide or carbamide peroxide as the active ingredient. These solutions have a higher concentration than over-the-counter products, and they are formulated to remain stable until application. Once applied, the peroxide breaks down and releases reactive oxygen molecules, which is a process that penetrate the tooth’s porous enamel and dentin layers. These reactive molecules then interact with and break apart the chemical bonds of staining compounds, rendering them colorless.
The effectiveness of the peroxide solution may be related to its stabilizing agent ingredients. Gels can be formulated near a neutral pH to minimize tooth surface demineralization during procedures. Desensitizing agents, such as potassium nitrate or fluoride, may be added to the formula to help manage tooth sensitivity that may occur during treatment.
Light-powered Enhancement
Some in-office whitening procedures incorporate a specialized light or heat source during treatment. The light itself does not bleach the teeth; its function is to accelerate the chemical reaction of the whitening gel. Exposing the peroxide to light or controlled heat may increase its effectiveness. This speeds up the chemical breakdown of stains and occurs more quickly than it would otherwise.
Practitioners implement specific safety protocols during light-activated procedures. A protective barrier is applied to the gums and soft tissues, preventing contact with the teeth whitening agent. Protective eyewear is also provided to shield your eyes from the high-intensity light. These measures are part of the standard procedure for this type of whitening treatment.
Take-home Tray Technology
Dentists may provide customized take-home whitening kits as an alternative or follow-up to in-office treatments. These kits include custom-molded trays that fit your teeth precisely, allowing for even application of the whitening gel. The close fit also helps prevent the gel from leaking out and irritating your gums. Carbamide peroxide, the active ingredient in these gels, is stable and breaks down into hydrogen peroxide and urea.
The science behind take-home trays involves a slower, more gradual release of the active whitening agent. Your dentist provides specific instructions on how long and how often to wear them, based on the gel’s concentration and your individual needs. The gradual process allows for whitening to occur over several days or weeks. This method offers a different approach by focusing on:
- Gradual whitening
- Controlled application
- Extended contact time
