The Science of LED Light

The Science Behind Teeth Whitening

In general, the teeth whitening process works by treating the teeth with an agent which may or may not be bleach-based. Then, to speed up the reaction, a blue light is shined on the treated teeth. In the past, Ultra Violet (UV) light has widely been used as the light source.

However, there are now concerns over the risks of using UV light. UV light is a form of ionizing radiation which can cause the mutation of cells and potentially cancer. This is of particular concern in the mouth because the oral tissues are very sensitive, as shown in this study.


What Is LED Light?

LED stands for 'Light Emitting Diode'. It is a device which releases visible light when supplied with an electrical current. Often, the light is a single color which can be anywhere between red and blue-violet on the visible light scale. LED lights can be very intense and often brighter than their halogen or incandescent lamp counterparts. They are also a lot cooler as they have very efficient heat-dissipating designs.

LED lights do not need much power but are highly efficient and last a long time, particularly in comparison to other light sources. They do not have a warm-up time, so they switch on at their highest intensity immediately. They are a form of visible light, so they are not a type of ionizing radiation, which means they cannot cause cell mutations and therefore cannot cause cancer.

LED can be used in place of the UV light as a safer alternative to speed up the whitening reaction but without the risks of UV light.

A study published in the Open Dentistry Journal found that light speeds up the whitening process, and is backed up by many other studies. This is found in particular when LED activator light is used in conjunction with carbamide peroxide-based whitening agent gels.Where in the past, UV light had been used as a catalyst to speed up the time taken for teeth whitening to occur, LED light is now much safer and more accessible.


Is LED Teeth Whitening Safe?

LED whitening has been developed to be safe for home use. The use of an LED light source as opposed to older, UV light sources, is much safer. However, bear in mind that while the light is safe, teeth whitening involves putting bleach into your mouth, so it is important to follow the instructions which are specific to each different kit.
