Teeth Whitening

 During the LED teeth whitening process, users first treat the teeth with a chemical agent that has bleaching properties. LED light is used to activate the lightning agent and start the chemical reaction.
When this interaction happens, the blue LED light penetrates the enamel and lifts existing stains.
How Does an LED Light Make Your Teeth Whiter?
LED light works with a tooth-whitening agent to whiten teeth by activating the whitening agent and starting the chemical reaction.
An LED light will not change the color of the teeth if used alone. It acts as a catalyst to speed up the whitening process's reactions when combined with a whitening agent. 

Dont Consume Foods that Can Stain Your Teeth
The first few days after treatment are the most critical. Avoid dark foods/liquids, drink through a straw when you can, dont smoke, and brush and floss frequently. Keep in mind, the less you indulge in staining foods and drinks, the longer your results should last.

Thinning tooth enamel.

It's not uncommon to notice your teeth growing yellow as you grow older. If you find some of your teeth growing white while other parts are turning yellow after whitening, it might be a sign that you've got thin tooth enamel.

The pores in the enamel are gently opened up so that dental bleaching agents can reach the stains beneath the surface of your teeth. About two days after the whitening procedure is complete, the pores close back up, leaving the enamel in its original state.
