What Is The Blue Curing Light Dentists Use And Is It Dangerous?

Have you noticed the glow of blue light during your dental visits?  People often wonder what this light is for used for and whether it’s dangerous or not.  The blue light is called a curing light and it is used for setting white fillings.

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 molded 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 curing light is a very strong blue light.  It is 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 as 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 lights 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.
