Adult and pediatric patients should have equal access to curing lights, and those lights should be able to move into the proper positions without damaging the composite. Between 750 and 2000 milliwatts per square centimeter of intensity is recommended for a successful treatment.

Overheating and energy waste may result from using a curing light with a wattage greater than 2,000, and the composite will not cure any more quickly as a result. Dentists should rely on the composite manufacturer’s recommended curing times rather than those provided by the light manufacturer, even when higher wattages are visually appealing.


Have you seen a blue light shining down on you from the ceiling of the dentist’s office? Many people are confused about the purpose of this light and worry that it may do harm. A curing light, or blue light, is used to harden white fillings.

Types of Curing Lights

LED Lights – L.E.D., or Light Emitting Diode, restricts the current flow of light into one direct through its connection to a circuit. With these curing lights, they’re lightweight, small, have a long battery light, and by today’s standards give off the most consistent curing by its design. L.E.D. can refer to either blue light or multi-wave light of both blue and violet. The blue light activates the photoinitiator while the multi-wave activates both the photoinitiator and alternative initiator. Some may lack tip selections, lack timers, and may have a harder time curing certain composites. Most new-style L.E.D. curing lights have a better time with beam divergence, and any tips that fan out the light in a cone shape can divert the curing process and divert the energy needed to cure the composite.

Halogen – While considered to be an outdated product by industry standards, halogen lights have a reliable long track record for creating consistent cures. Halogen curing lights have a wider selection of curing materials it can work with due to its wide bandwidth. However, its design causes the need for cooling fans and a cord but does benefit from lower prices.

Plasma Arc – A plasma arc curing light consists of having an aluminum oxide vessel containing high energy xenon gas under 150 psi. These curing lights produce focused beams and typically are designed within large base units and small tips for the desired effect. However, it lacks the ability to cure all materials and can be quite expensive.

Argon Laser – Argon lights generate light through applying energy to the atoms of argon gas, where the electrons are raised higher in numbers to an unstable level, and then release light through the argon gas. As some of the most expensive forms of curing lights, these create fast curing times and require a large unit to encompass the laser. However, it may not cure all materials and require small tips and cords to function.


What Does The Blue Light Do?

The blue light sets fissure sealants, fillings and cement in a matter of seconds. When fillings are placed in the tooth they are very soft so they can be moulded to the correct shape by the dentist. When the dentist is happy with the shape of the filling they will set it with this light. The blue light makes the filling go rock hard and strong enough to chew on. The blue light is also used when having braces fitted to set the cement which holds the brackets on your teeth.

Is The Curing Light Dangerous Or Harmful To Look At?

The dental curing light is a very strong blue light. It it not a laser or a UV light so it will not cause any damage to your teeth or gums. The only danger is if you look directly at the light for too long. Similar to how your eyes will hurt if you look at the sun for too long. Dentists and assistants are advised not to look at the light for long periods of time. There are two types of curing lights used by dentists. There is a halogen curing light and an LED curing light. Most modern curing lights are LED as they do not overheat like the halogen curing lights do. The only danger with the halogen light is that the heat it produces could potentially hurt the pulp of the tooth or the soft tissues in the mouth. Although this is possible, it is very unlikely. The majority of dentists use LED curing light these days.

What Does The Orange Shield Do?

The orange shield is a filter so that your dentist and assistant can still look in your mouth without the strong blue light hurting their eyes. The light is okay to look at for a few seconds but it’s not nice for dental staff to look at for too long.
