The Science Behind Teeth Whitening: Understanding How Whitening Products Work
Teeth whitening has become one of the most popular cosmetic dental procedures in Edmonton and beyond. Its appeal lies in its ability to provide a brighter smile relatively quickly and effectively. However, to appreciate the full value of teeth whitening, a deeper understanding of the science behind the process is essential.
The Cause of Tooth Discoloration
Before diving into how whitening products work, it’s necessary to understand what causes tooth discoloration. The primary culprits include food and beverages with intense color pigments, like coffee, red wine, and tea, which attach to the white outer part of your tooth (enamel). Additionally, tobacco use and the natural aging process contribute to the yellowing of teeth over time.
The Structure of Teeth
To grasp how whitening products function, one must comprehend the tooth’s structure. The enamel is the hard, outer surface, which is translucent, and below it lies the dentin, which is naturally yellow. The color of the dentin, coupled with the staining of the enamel, influences the overall appearance of the teeth.
Active Ingredients in Whitening Products
The active ingredients in most whitening products are hydrogen peroxide or carbamide peroxide. These chemicals act as bleaching agents that break stains into smaller pieces, reducing the concentration of the color and leaving teeth looking brighter.
How Whitening Products Work
Peroxide Penetration
When applied to the teeth, the peroxide in whitening products penetrates the porous enamel and reaches the dentin. There, it reacts with the discolored molecules responsible for staining, breaking the chemical bonds that hold the stains together.
Oxygen Molecules and Stain Removal
As the peroxide breaks down, it releases oxygen molecules that interact with the stained molecules in the teeth, dispersing them. This process is what physically lifts the stains, leading to the whitening of the teeth.
The Role of Light
Some teeth whitening treatments involve a special light that claims to accelerate the whitening process. The light or laser acts as a catalyst, purportedly speeding up the chemical reactions of the peroxide.
Types of Whitening Treatments
- In-Office Whitening: Professional in-office whitening, like the services offered at Dr. Molly Rodgers Dental, uses high-concentration peroxide gels and controlled heat to provide immediate results, often in a single session.
- At-Home Whitening Kits: At-home whitening kits prescribed by dentists contain peroxide-based gels or strips and custom-made trays to fit the teeth. They are designed for use over a period of days or weeks, depending on the desired level of whitening.
- Over-the-Counter Products: Over-the-counter whitening options include low-concentration gels, whitening toothpaste, and strips. These products work over time and are less potent than professional treatments.
Safety and Effectiveness
The safety and effectiveness of teeth whitening largely depend on the method chosen and adherence to the product’s instructions. Professional treatments offer a balance of high effectiveness and safety when conducted under the supervision of a dentist.
Post-Whitening Care
After teeth whitening, it is vital to maintain oral hygiene by brushing and flossing regularly. Avoiding substances that stain teeth can prolong the results of the whitening treatment.
Sensitivity and Whitening
Teeth sensitivity is a common side effect of whitening treatments due to the peroxide. Most people experience temporary sensitivity that subsides after the completion of the treatment.
