The Science Of Teeth Whitening: Exploring Different Methods and Their Pros and Cons

June 22, 2023

A radiant smile can do wonders for our appearance and self-confidence. However, as time goes by, our teeth may lose their natural whiteness due to ageing, lifestyle choices, and dietary habits. Luckily, teeth whitening has become a popular solution to restore the brightness of our smiles. Let’s explore the science of teeth whitening and look at various methods available to help you achieve a brighter and more confident smile.

Over-the-Counter Whitening Products

Over-the-counter whitening products, such as toothpaste, gels, and strips, contain mild bleaching agents or abrasive ingredients. These components work by removing surface stains through a process called adsorption, where the stain molecules adhere to the active ingredients and are then rinsed away. However, the lower concentration of active ingredients in these products compared to professional treatments means that the whitening effects may be limited. The level of effectiveness can vary from person to person, and some people may experience temporary tooth sensitivity or gum irritation due to the abrasive nature of these products.

Tray-Based Whitening

Tray-based whitening, on the other hand, involves using custom-fitted trays filled with a whitening gel. The trays ensure that the gel comes into close contact with the teeth, allowing for a more even distribution of the active ingredients. The whitening gel typically contains hydrogen peroxide or carbamide peroxide, which work to break down the pigmented molecules responsible for tooth discolouration. The whitening process occurs through a chemical reaction where the active ingredients release oxygen molecules. These oxygen molecules penetrate the enamel, breaking apart the discoloured molecules and reducing their intensity. However, tray-based whitening may require several weeks of regular use to achieve noticeable results.

In-Office Professional Whitening

In-office professional whitening, such as the treatments offered at The Smile Bar, provides a faster and more significant improvement in teeth whiteness. During these procedures, a high-concentration bleaching gel is applied to the teeth, and a special light or laser is used to enhance the whitening process. The light or laser serves as an activator for the gel, speeding up the breakdown of stains and increasing the penetration of the active ingredients into the enamel. This professional-grade approach ensures close monitoring by dental professionals and reduces the risk of complications.

The Smile Bar goes a step further by incorporating UV-free LED Plasma Light Technology into their advanced teeth whitening system. This cutting-edge technology enhances the whitening process by working in conjunction with the specially formulated whitening gel. The UV-free LED plasma light emits a specific wavelength of light, which helps to activate the gel and accelerate the breakdown of stains. This technology ensures faster and more efficient results, while also being a safe and gentle alternative to traditional UV light systems. It reduces the risk of adverse effects, making it an excellent choice for those with sensitive teeth or special dental considerations.
