Lightning is one of the most dramatic effects of electricity. Electricity is the set of physical phenomena associated with the presence of electric charge.

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.
Many power brushes have timers and this can help you brush the recommended two minutes. Brushing is not enough; you also need to clean inbetween teeth to thorougly remove plaque. Dental floss is the most recommended product by dental professional, but it requires a high level of dexterity and can be hard to do for many people.
