Purple Light and Teeth Whitening

What Does Purple Lightening Do For Your Teeth?

When it comes to teeth whitening, there is no such thing as Purple Lightning. A new approach for dental bleaching, however, uses Violet light. According to some emerging research, Violet light has a wavelength of around 405-410 nm. This wavelength is closer to the UV range and still is in the visible light spectrum. Dentists are bringing forward the concept of using Violet light for teeth bleaching and whitening since for a specific reason.

Violet light activates a specific type of hydrogen peroxide called photogenerated hydrogen peroxide (PGHP). This stable form of Hydrogen Peroxide, when exposed to Violet light, can break down into free radicals. These radicals, when penetrating into tooth enamel, break down stains and discoloration. It, therefore, acts for teeth bleaching or teeth whitening. 

How Does UV Teeth Whitening Work?

Violet light has been showing promising progress in teeth bleaching, but remember, there isn’t any such thing as ‘Purple Light .’The common phrases you may have heard or read of are basically several UV (ultraviolet) light treatments. 

The UV (ultraviolet) light treatments work in a simple manner. Initially, the dental professional applies a gel (basically a peroxide-based bleaching agent) to patients’ teeth. Once the gel is well spread, the professional will use a UV light all over the teeth to activate the bleaching agent.

The light will help to step up the chemical reaction between the patient’s teeth and the gel. The said treatment, after a few sittings, will aid in whiter and brighter teeth. The results may start getting visible from the first or second sitting only.

Is UV Teeth Whitening Safe?

Whether UV Teeth Whitening is safe or not is a topic of long debate. As per some dental studies, UV light can be an effective method for speeding the teeth whitening process. Similarly, there are studies that suggest that UV lightening can be unnecessary and lead to potential dental health dangers. 

The effects of UV light on gums and other sensitive oral health tissues can be extremely harsh. UV light can, in fact, damage skin cells leading to Skin cancers (not dedicated claimed). However, the risk involved in the amount of UV light used in dental treatment is very high or prolonged. If the light used for whitening is relatively low, the risks will decrease (but still be there).

Therefore, concerning the possible downsides, a lot of dentists prefer sticking to alternative teeth whitening methods than UV light. UV light alone isn’t a treatment, and there is a range of other possible methods to go with.

Some dentists also choose to use Blue LED lights since they are way too safer than UV lights. It is better to stick with a dentist that focuses on a safe and effective approach than following the market hype. 

There are several rumors that associate UV Light Teeth Whitening and Cancer, but evidence supporting the same is low or not very powerful. The idea of associating UV Light Teeth Whitening and Cancer came from the claims of the American Cancer Society.

According to their studies, UVB rays which are more energetic than UVA rays, can damage the DNA in skin cells and make it likely to cause skin cancer. However, UVB rays aren’t used for teeth whitening; therefore, the claim for cancer can’t be blindly supported.

The risk of UV teeth whitening treatment associated with oral cancer is quite low. It is because the UV light used in teeth whitening treatment isn’t very harsh, even low than the UV radiation of sunlight. Therefore, exposure to these treatments alone cannot lead you to cancer. However, it is important to remember that UV radiation of any kind carries risks to health in some or the other way.
