When the enamel layer thins or wears away, the teeth begin to look darker Some people have enamel that is naturally thinner. Brushing your teeth is an important part of your  daily dental care routine. Brush your teeth twice a day with a soft-bristled brush. The size and shape of your brush should fit your mouth allowing you to reach all areas easily. Replace your toothbrush every three or four months, or sooner if the bristles are frayed. A worn toothbrush won’t do a good job of cleaning your teeth. use any fluoride toothpaste. The proper brushing technique is to: Place your toothbrush at a 45-degree angle to the gums. Gently move the brush back and forth in short (tooth-wide) strokes.  Brush the outer surfaces, the inner surfaces, and the chewing surfaces of the teeth. To clean the inside surfaces of the front teeth, tilt the brush vertically and make several up-and-down strokes.
