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.
When you brush your teeth: 1  Brush your teeth 2 times a day, in the morning and at night. 2  Use a toothbrush with soft, rounded-end bristles and a head that is small enough to reach all parts of your teeth and mouth. Do not scrub. 2  Vigorous brushing can make the gums pull away from the teeth and can scratch your tooth enamel. 3  Brush all surfaces of the teeth, tongue-side and cheek-side. 4  Pay special attention to the front teeth and all surfaces of the back teeth.
