Do you want whiter teeth with up to 8 shades from the comfort of home? There are a wide range of reasons that discolor teeth. Smoking, coffee consumption, poor nutritional decisions and medications are the most common. Aging can also affect the brightness and color of our teeth. The enamel begins to thin as we age and is more prone to stains. It is crucial to have a healthy layer of enamel. Using an LED whitening kit produces a protective layer that helps combat discoloration. WHAT IS LED LIGHT? LED means light emitting diode. The purple LED (405-410 nm) is a breakthrough in teeth whitening procedures. Its short wavelength and high frequency of vibrations interact with the pigment molecules in dentin, decomposing them selectively into smaller molecules. This weakens their chemical bonds, causing ruptures that lead to a whiter structure. LED lights are very bright, but not as hot as incandescent or halogen lamps.
