Research has shown that the modified Bass/Bass technique is more effective than horizontal brushing in reducing plaque and gingivitis.
The Bass/Bass technique is built around the fact that the brush should be held at an angle of 45° when touching the teeth. This is said to be more effective when it comes to reducing bacteria when the brush removes plaque. This is when the brush touches the teeth at the gum line, which removes plaque that is often hard to reach. This type of brushing is best done for at least two minutes. More research should be done to see if this method is better than other methods for brushing, but it can be an effective addition to daily oral hygiene routines.
