Did you know that in as little as 20 minutes, you might have your smile brightened by 5–10 shades? Additionally, professional teeth whitening techniques do not include the use of a dental drill or needles. Instead, the steps are as easy as attaching an LED light, adding the whitening chemical, and waiting.

In this circumstance, however, that is not the case. In fact, there are quick and simple ways to have a whiter, brighter smile thanks to modern technology. And the light does contribute to the quicker whitening process, yeah. However, merely grinning at an LED light will not make your teeth whiter. You must first comprehend the fundamentals of how teeth whitening functions to comprehend how LED lights contribute to the whitening procedure.

What are the Fundamentals of Teeth Bleaching?

Your teeth will first be cleansed when you go to your neighborhood dental practice to have them professionally whitened so that the whitener can be applied uniformly to the surface of your teeth. Additionally, you will be provided instruments that are designed to hold your mouth open and safeguard your mouth’s sensitive tissues while the whitening process is being done. The teeth-whitening gel will stay on your teeth for roughly 20 minutes after application.

Because teeth are porous, the enamel and dentin layers of the tooth absorb the whitening gel. Hydrogen peroxide, which safely absorbs into the body after removing stains, is the active component in whitening gels. While cosmetic dentists employ higher doses of hydrogen peroxide to achieve quicker, more effective outcomes, most over-the-counter whitening treatments use lower quantities.

This is so that an oxidation reaction can take place when hydrogen peroxide is sprayed to the teeth. The discoloration of the molecules’ molecular bonds is broken by the oxidation reaction, which removes the stains. Simply put, hydrogen peroxide whitens teeth by dissolving stains from the enamel and dentin layers. The whitening gel will still work for the first 24 hours after application even though it is only on your teeth for a brief period.

How LED Lights be Useful?

You may be asking how an LED light can facilitate this procedure at this stage. When exposed to power, an LED, or light-emitting diode, emits only one hue of light on the visible light spectrum. UV, or ultraviolet radiation, was once employed to speed up the whitening process. However, it has been discovered that UV light can result in cancer-causing cell alterations.

Thus, LED lighting swiftly took the place of UV lighting in teeth-whitening processes. LED lights use very little power, have a long lifespan, and do not need to warm up before using. Due to their capacity to dissipate heat, they are much cooler even though their light is more powerful than other types of light. They are the perfect light for teeth whitening because of all these factors.

Research has revealed that LED lights speed up the chemical reactions that remove stains from teeth, which is the main reason they are utilized in teeth whitening methods. As previously stated, whitening chemicals work for 24 hours. Therefore, accelerating the chemical processes simply allows for the removal of more stains in the same amount of time. In the end, your smile will be more radiant the more stains are eradicated. In general, a single use of LED teeth whitening machine can lighten your smile 6–8 shades.

Overall, the use of LED lights during teeth-whitening procedures has increased the efficiency of whitening agents, resulting in smiles that are whiter and brighter. However, the major component of whitening treatment continues to be the whitening chemical. Even though an LED light cannot create results on its own, it can produce amazing results when combined with whitening gels.
