The American Dental Association recommends brushing teeth twice a day for two minutes using a fluoride toothpaste. Brushing for two minutes has been shown to achieve clinically significant plaque removal1 and use of a toothpaste containing fluoride enhances fluoride concentration levels in biofilm fluid and saliva, and is associated with decreased risk of caries and remineralization of teeth.2

There are a number of techniques for brushing teeth; any of which may have advantages depending on a patient’s particular needs.3 In general, the American Dental Association suggests that people place the toothbrush against the gumline at a 45-degree angle to remove plaque from above and just below the gingival margin, and move the toothbrush gently back and forth in short strokes.4 To clean the inside surfaces of the front teeth, they should tilt the brush vertically and make several up-and-down strokes. 

Regardless of the technique used, brushing should touch upon all surfaces—inner, outer and chewing. Also, when brushing, the ADA recommends that people use a soft-bristled toothbrush and apply gentle pressure, both of which may help reduce the risk of gingival injury.5, 6
