Most people are aware that brushing their teeth twice a day is one of the most important practices for removing plaque and bacteria and keeping teeth clean. However, brushing may only be effective if people use the correct technique.
People should brush using small circular motions, taking care to brush the front, back, and top of every tooth. This process takes between 2 and 3 minutes. People should avoid sawing back-and-forth motions.
Brushing too hard or using a hard-bristled toothbrush can damage tooth enamel and the gums. The effects of this may include tooth sensitivity, permanent damage to the protective enamel on the teeth, and gum erosion.
The American Dental Association (ADA) recommends using a toothbrush that has soft bristles. They also state that people should change their toothbrush every 3 months or when the ends start to look frayed, whichever comes first.
