Did you know that you can brighten your smile by about 5-10 shades in as little as 20 minutes? Not only that, but the professional teeth whitening procedure is also needle-free and does not require the use of a dental drill. Instead, the process is as simple as placing the whitening agent, applying the LED light, and letting it sit.
Sound too good to be true? Well, it’s a rare case, but that’s not the case. Modern technology actually makes it possible to have a whiter and brighter smile quickly and easily. And, yes, light does play a role in speeding up the whitening process. However, simply smiling into an LED light will not make your teeth whiter. To understand how LED lights play a role in the whitening process, you must first understand the fundamentals of teeth whitening. Next, the teeth whitening LED light supplier will share the following content with you.
What is the foundation of teeth whitening?
When you visit your local dental office for professional teeth whitening, your teeth will first be cleaned to ensure that the whitening agent can be applied evenly to the surface of your teeth. You will also be given special tools for opening your mouth and protecting the soft tissues of your mouth during the whitening process. After application to the teeth, the whitening gel will remain in place for approximately 20 minutes.

Since teeth are porous, the whitening gel is absorbed by the enamel and dentin layers of the teeth. The active ingredient in the whitening gel is hydrogen peroxide, which removes stains and is then safely absorbed by the body. While most over-the-counter whitening products use low concentrations of hydrogen peroxide, cosmetic dentists use higher concentrations for faster, more effective results.
This is because when applied to the teeth, hydrogen peroxide acts as a catalyst for the oxidation reaction that occurs. The oxidation reaction breaks the molecular bonds of the discolored molecules, causing the stain to disappear. Simply put, hydrogen peroxide dissolves the stains on the enamel and dentin layers, resulting in whiter teeth. Although the whitening gel will only stay on your teeth for a limited time, it will remain effective for the first 24 hours after application.
So, what does the teeth whitening LED light do?
At this point, you may be wondering how teeth whitening LED lights can help with this process. LEDs, or light emitting diodes, emit a single color of light in the visible spectrum when they are electrified. In the past, ultraviolet or UV light has been used to help with the whitening process. However, UV light has been found to cause mutations in cells that can lead to cancer.
As a result, LED lights are quickly replacing UV lights for whitening procedures. LED lights require minimal power, have a long lifespan, and do not require a warm-up period to be effective. Although their light is more intense than other types of light, they are also much cooler due to their ability to dissipate heat. All of this makes them ideal for teeth whitening.
One key reason LED lights are used in teeth whitening procedures is that studies have shown that they accelerate the chemical reaction that removes tooth stains. As mentioned earlier, whitening agents have an expiration date of 24 hours. Therefore, accelerating the chemical reaction simply means that more stains can be removed in that time. Ultimately, the more stains that are removed, the brighter your smile will be. On average, LED teeth whitening can lighten your smile by 6-8 shades in a single whitening session.
Overall, adding LED lights to your whitening procedure improves the effectiveness of the whitening agents, giving you a brighter, whiter smile. Nevertheless, whitening agents are still a key element of whitening treatments. While LED lights alone will not achieve results, they produce amazing results when used in conjunction with whitening gels.
