Light Emitting Diode System (LED) teeth whitening treatments are becoming a more popular teeth whitening method. They speed up the whitening process so you can achieve a brighter smile in less time.
However, there are many concerns regarding the safety of LED teeth-whitening lights. We discuss them in this article.
Current research shows that LED teeth whitening is safe and effective for at-home use. Users shouldn’t experience adverse side effects if they follow the manufacturer’s instructions.1
LED light on your teeth is safer than ultraviolet (UV) light. UV light can cause cell mutations, while LED lights don’t. LED teeth whitening kits speed up the whitening reaction without the risks associated with UV light.2
Remember that the results from any teeth whitening treatment will depend on the user’s lifestyle and the cause of their teeth discoloration. Always talk to a dental professional to know whether you’re a good candidate for whitening treatments.
