If you're considering teeth whitening, you may be wondering whether to choose an LED or UV (also known as Violet) light. In this article, we'll compare LED and UV teeth whitening lights, and help you decide which one is right for you.

LED teeth whitening

LED teeth whitening is a popular teeth whitening method that uses cold blue light technology to speed up the bleaching process. LED lights are usually gentler on teeth and gums and therefore, are widely used by both dentist professionals and over-the-counter providers.

One of the main benefits of LED teeth whitening is that it is much faster than other methods. In most cases, a 10–20-minute session is all that is needed to achieve noticeable results. This makes it a great option for people who are short on time or who want to get their teeth whitened quickly.

Another advantage of LED teeth whitening is that it is generally less expensive than other methods, such as professional in-office teeth whitening.

UV teeth whitening

UV teeth whitening is another teeth whitening method that uses light to speed up the bleaching process. UV lights are usually more powerful than other methods, such as LED teeth whitening. However, they can also be more harmful if not used properly.

The main benefit of UV teeth whitening is that it’s a more powerful option as the light uses higher frequencies and emits heat.

There are some downsides to be aware of as well. One of the biggest disadvantages is that it can be more harmful to teeth, gums, lips and mouth due to the heat that the light emits. It is also recommended to avoid contact with the eyes as the UV rays can be harmful.

Which is better

There is no one definitive answer to the question of which teeth whitening method is better. It ultimately depends on each individual’s needs and preferences.

Both are non-invasive, affordable options and provide instantly whiter teeth. Compared to UV light, LED light is safer but is still as effective.

Ultimately, the best teeth whitening method for you will depend on your individual needs and preferences. If you are unsure of which method to choose, it is always best to consult with a qualified dentist or dental specialist.
