For example: Blue light can effectively prevent and heal dental cavities. Now taught in dental schools and used by many dentists, blue light directed onto the outside of the cheek will destroy bacteria in the mouth that creates cavity-causing plaque.
A really great way to use blue light is to rinse the mouth the blue light-infused water. How to make it? Take a cobalt blue bottle (without label or words), fill it with water and sit it in a window for 24 hours. The light coming through the glass will infuse the water with the blue vibration and give the same effect as blue light. You can even taste a difference in this water versus plain water! Does it work? Absolutely. A client of mine healed 3 cavities using only blue water morning and evening. His dentist was amazed at the improved quality of his teeth at their next appointment.
