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.
Mouthrinses and mouthwashes are not intended to replace tooth brushing. It is important to brush your teeth twice a day with a fluoride toothpaste. One of those times should be before going to bed to remove all food particles from teeth and prevent the length of attacks by food on teeth. Using a rinse after brushing can help freshen breath and prevent tooth decay.
