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.
Brushing just a few teeth at a time, work your way around your mouth in a circle so that you get every tooth, spending about 12 to 15 seconds in each spot. If it helps, you can divide your mouth into quadrants: top left, top right, bottom left, and bottom right.
