The same ultraviolet light that causes sunburn and skin cancer can damage your gums, lips and eyes during a light-assisted teeth bleaching, a new study finds.
What is the blue light at dentist?
A dental curing light is a piece of dental equipment that is used for polymerization of light cure resin based composites. It can be used on several different dental materials that are curable by light. The light used falls under the visible blue light spectrum.
Are blue lights bad for your teeth?
It may cause burning of soft tissue, gum irritation, damage to teeth and increased tooth sensitivity. Comparatively, the American Chemical Society performed a study that tested the activation of blue light on the teeth whitening process and found no significant damage to the teeth’s enamel.
Is dental curing light harmful?
Fortunately, the blue dental curing light normally won’t hurt your teeth. Most of the modern curing lights use a blue LED light for curing. This heat could cause damage to the dental pulp — the innermost tissue composed of nerves and blood vessels inside of your tooth.
Why do dentists use UV light to harden fillings?
Ultraviolet light is used to cure, or harden, composite fillings. White, tooth-colored fillings have a photo initiator within them that responds to ultraviolet light. The energy within the light causes the initiator to polymerize the composite material and harden it into its final configuration.
