Dental Curing Light: Everything You Need To Know

When filling or restoring teeth, dentists often use a blue light tool. This dental office equipment is called the curing light. What does it do? Can it cause damage to the body? After reading this article, you will have a more comprehensive understanding of LED curing light.

What Is The Curing Light?

Light-activated dental materials are an integral part of dental equipment tools, including certain sealants, resin-based cement, and composite restorative materials. And the curing light, a dental light curing unit (LCU), is a handheld light-emitting device used to cure such light-activated polymer-based restorative materials (PBRM).

Dental curing lights emit a bright, concentrated blue light that is used to set or cure fillings and sealants quickly and efficiently. There are two main types of common dental curing lights - halogen curing light and LED curing light, both of which harden dental work into place in just a few seconds.

Is The Blue Light From The Curing Light Dangerous?

The dental curing light is completely safe. Although the blue light is concentrated, there is no radiation, and it is not a laser that is not enough to harm your teeth or gums. Sometimes the dentist may ask you to wear protective goggles, which are simply to prevent eye strain caused by gazing at the light for long periods.

The blue light from the dental curing light is very bright and can cause the same discomfort as gazing excessively into the sun. But it is not as intense as the arc flash of welding that stings your eyes.

In the past, halogen light curing machines could generate too much heat, potentially dangerous to the soft tissues in the mouth. Therefore, most dentists today tend to use LED curing light, which is just as effective while maintaining a low temperature.

Oral Ergonomics Of The LED Curing Light

In general, the LED curing light with oral ergonomics design gives more flexibility to dental operations. For example, the LED curing light head can reach difficult positions in the mouth. It is especially suitable for children who may not be able to sit still or for older adults with a limited range of motion in the jaw.
