21 Mar The LED light in teeth whitening treatment.
Having a bright, white smile is something many people strive for, and teeth whitening has become an increasingly popular cosmetic procedure. In-office teeth whitening treatments are a fast and effective way to achieve a brighter smile, and one of the key tools used in these treatments is LED light.
LED light is used in teeth whitening because it does not pose the same risks as UV light. In this article, we’ll take a closer look at why LED light is used for in-office teeth whitening, and explore the potential harm of UV light.
What is LED Light?
LED stands for “light emitting diode,” and these lights produce a narrow spectrum of visible light. LED light is used in a variety of applications, from lighting to electronics, and is known for its energy efficiency and long lifespan.
In the case of teeth whitening, LED lights are used to accelerate the whitening process by activating the hydrogen peroxide gel that is applied to the teeth. The light waves produced by the LED activate the gel, which breaks down the stains on the teeth and leaves them looking whiter.
Why Use LED Light for Teeth Whitening?
There are several reasons why LED light is preferred for in-office teeth whitening treatments. Firstly, LED lights are safe to use and do not emit harmful UV radiation. This is important because UV light can cause damage to the skin and increase the risk of skin cancer.
In addition, LED lights are highly effective at accelerating the whitening process. Because they produce a narrow spectrum of light, they can be calibrated to a specific wavelength that is optimal for teeth whitening. This means that they can deliver targeted, precise light waves to the teeth, which results in faster and more consistent whitening results.
Finally, LED lights are energy-efficient and have a long lifespan. This means that they can be used repeatedly in teeth whitening treatments without needing to be replaced, which helps to keep costs down.
The Harm of UV Light
While UV light can also be used in teeth whitening, it is not the ideal method due to the potential harm it can cause. UV radiation is known to cause skin damage and increase the risk of skin cancer, and prolonged exposure to UV light can also damage the eyes.
In addition, UV light can cause the hydrogen peroxide gel used in teeth whitening to break down too quickly, which can result in inconsistent whitening results. This is because the UV light can cause the gel to dry out before it has had a chance to fully penetrate the teeth. In some cases, UV light can cause additional pain since it generates extra heat.
Overall, LED light is the preferred method for in-office teeth whitening due to its safety, effectiveness, and efficiency. By using LED light in teeth whitening treatments, patients can achieve a brighter, whiter smile without exposing themselves to harmful UV radiation and unnecessary sensitivity.
