The soft composite filling is made up of many small parts called monomers. For the material to set hard, these monomers should link up together to form chains called polymers. Shining the blue curing light activates the material to form polymer chains and harden.

How long does blue light on teeth last?

Studies show that using UV light to whiten your teeth is four times more dangerous than sunbathing. It can also cause toothaches, mouth infections, stomach problems, and nerve damage.

Does LED blue light whiten teeth?

As with UV light, halogen light is best used in dental offices. LED (light-emitting diode) produces blue light to increase the teeth whitening process without any radiating heat to the teeth.

Why do my teeth glow in UV light?

Are you wondering why this phenomenon happens? Your teeth will glow in the dark because they naturally contain phosphor. In fact, your fingernails also contain phosphor so they'll glow as well! Phosphorus is actually the second most abundant mineral in your body, with calcium being the first.

Does teeth whitening work without the light?
