Manufacturers are producing a greater variety of toothbrushes incorporating different designs for handles, heads and bristles.

Currently, dental professionals recommend the following:

  • for children, a small toothbrush head, approximately 20 mm X 10 mm;
  • for adults, a slightly larger toothbrush head, approximately 22-28 mm X 10-13 mm.

A general guide is that the size of the brush should be selected to suit mouth size, with smaller brushes being more suited to smaller mouths. Whether straight handles or angled handles are used is a matter of personal preference. People who experience some difficulty cleaning their back teeth are advised to use an angled brush. Fundamentally, the best brush is the one that enables the user to clean their teeth thoroughly without causing trauma.

The frequency with which you should replace your toothbrushes has yet to be correlated with oral health. The most helpful guide is to replace a toothbrush when the bristles begin to show signs of wear. Toothbrush handles can also be adapted to improve the grip by the user. Electrical or battery operated toothbrushes are often useful for people who have difficulty holding an ordinary toothbrush, such as persons with poor motor control or a physical disability.

In short;

  • Toothbrushes should be replaced when bristles show signs of wear.
  • Brushing is more effective with multi-tufted, small-headed toothbrushes with soft to medium nylon filaments and a comfortable handle.
  • Powered brushes with brush heads that rotate first in one direction and then the other (oscillate/rotate) are more effective at removing plaque than manual toothbrushes and can reduce gingivitis if used for over 3 months.
