GloSmile Home-Use Teeth Whitening Kit with Led Light provides a convenient and affordable way to whiten your teeth at home, without the need for professional assistance. Our specially made formula includes active ingredients designed to penetrate the discoloured molecules deep in your teeth and remove stubborn stains. The formula is activated by the accelerator light, which removes the deepest stains and speeds up the teeth whitening process. The whitening process begins when the LED light enters the tooth's structure and reacts with the molecules in it. The reaction creates heat inside the tooth, which causes a chemical reaction within the enamel, resulting in a whiter shade. Also, the blue light from LED lights has antibacterial properties that can help prevent plaque from forming on your teeth.
