The basics of getting LED teeth whitening is to follow simple protocols such as your teeth specialist applying whitener evenly on the surface, adding a protective tool to keep the mouth open, and protecting the soft tissues of gums and cheeks. 

In this article, we will cover the following:

  • Definition of LED teeth whitening;
  • The process of how does LED light whiten teeth;
  • LED teeth whitening pros and cons and side effects;
  • What customers think about LED whitening and if it actually works;

What Is LED Teeth Whitening?

Professional LED teeth whitening is a dental procedure done without a needle. The process includes using the whitening agent and LED light. Teeth whitening is any process that makes your tooth shade lighter. It can either be done by physically removing or chemically lightening the stain. When we talk about LED teeth whitening, teeth whitening agents are used, mainly hydrogen peroxide, and then teeth whitening LED light to lighten it. 

However, over-the-counter LED teeth whitening also exists and uses a similar method to professional whitening. In fact, to have a brighter smile, Americans spend $1.4 billion on nonprescription teeth whitening products each year. There is a global industry of cosmetic dental bleaching, with people around the world spending $3.2 billion on this service.

How Does LED Teeth Whitening Work?

If you are wondering how does led light whiten teeth, the method used to whiten your teeth with LED teeth whitening is straightforward. As mentioned in the section before: thanks to active agents (hydrogen peroxide) and with the help of the LED light, your teeth can be whitened in less than an hour. But, how is the process?

If you choose to get your teeth whitened by a professional, first, they will make an in-depth professionally clean before a whitening procedure so that the whitening agent can be applied evenly, and then they will use the LED light, key to the effectiveness of the treatment. The LED light is a single diode that emits light of a single color in the visible spectrum range when connected to power. It provides long-lasting effects as it accelerates the procedure that goes into tooth enamel and breaks off bonds of stains.

There are several ways to remove tooth stains and brighten your smile, the most common being hydrogen peroxide or carbamide peroxide. Hydrogen peroxide breaks down more quickly than carbamide peroxide, releasing most of its whitening power within the first 30 to 60 minutes. At the same time, Carbamide peroxide releases about 50% of its whitening power in the first two hours and can remain active for up to six additional hours.

The same method is used if you choose an over-the-count LED teeth whitening kit; however, the results won’t last the same and be as effective as with professional whitening. This is because with whitening kits you don’t get an in-depth cleaning, and also, the ingredients used in them are not as strong as the ones used with professional whitening as they are chemicals and should be applied by a professional if in higher concentration levels.

Pros and Cons of LED Teeth Whitening

As with any cosmetic procedure, LED teeth whitening has pros and cons. When done by an experienced dentist using the best teeth whitening products, this procedure can give you a brighter, whiter smile. However, it can also lead to enamel damage and tooth sensitivity.

As you can see in the LED teeth whitening pros and cons, several of the teeth whitening LED light side effects can affect your overall oral health.
