If brushing after each meal is not possible, rinsing the mouth with water after eating can reduce bacteria by 30%.

Toothbrushes. A vast assortment of brushes of varying sizes and shapes are available, and each manufacturer makes its claim for the benefits of a particular brush. People should look for the American Dental Association (ADA) seal on both electric and regular brushes.

In spite of the wide variety of nonelectric toothbrushes, both in shape and bristle design, a study of eight brands found no significant differences in effectiveness among them.

Electric toothbrushes, particularly those with a stationary grip and revolving tufts of bristles, can be advantageous for some people with physical disabilities. Electric toothbrushes with heads that move back and forth up to 4,200 times a minute remove significantly more plaque than ordinary brushes. Even more high-tech brushes are now available that use sound waves to remove plaque.

In general, studies have reported no differences between electric and manual toothbrushes in their ability to remove plaque. (One study showed considerable improvement in groups using sonic toothbrushes, particularly in those with moderate periodontal disease.) Experts recommend, however, that if a regular toothbrush works, then it isn't necessary to buy an expensive electric one.

For individuals with average dexterity, a four- or five-rowed, soft, nylon-bristled toothbrush is sufficient. The most important factor in buying any toothbrush, electric or manual, is to choose one with a soft head. Soft bristles get into crevices easier and do not irritate the gums. One study found that those who used a soft toothbrush had 4.7% of exposed tooth below the gum line compared to 9.4% with hard brush users. A useful toothbrush called Alert has been developed that flashes a red light when too much pressure is being placed on the gums.
