Lightning is one of the most dramatic effects of electricity. Electricity is the set of physical phenomena associated with the presence of electric charge. Although initially considered a phenomenon separate to magnetism, since the development of Maxwell's Equations both are recognized as part of a single phenomenon: electromagnetism.
A Dr. Benjamin S Fiss DDS , Dentist, answered. Brush your teeth in small circles, two teeth at a time, at a 45 degree angle to the tooth enamel. Brush your teeth at least two times per day slowly over 1-2 minutes. Ideally, you should brush your teeth after every meal and especially after eating sugary foods.
All surfaces of the teeth should be targeted, front, back, and all chewing surfaces. You should only need to brush for two minutes, if you use the proper technique. To reach the inside of the front teeth, it may help to use the toe of your toothbrush in a gentle up and down motion.
