In a review of recent studies Peter Robinson of Sheffield University in Sheffield, England, and colleagues found that the rotating brushes reduced plaque by 11 percent over manual toothbrushes and reduced the signs of gingivitis (inflammation of the gums) over the short term of one to three months.
The results were even more dramatic with long term use (more than 3 months) reduced gingivitis by 17 percent over manual brushes.
The researchers wanted to be clear that oral health is benefited greatly by proper brushing with manual toothbrushes but for those who are at higher risk of gum disease the use of an electric toothbrush with rotating heads may produce significant improvements in oral health.
They found the best type of brush is one that uses rotation brushes that alternate motion were best and found that ionic brushes and powered brushes that did not have a circular motion produced no better results than manual brushes.
Seniors are especially at risk for gum disease due to diseases such as diabetes, medications and other factors that can affect oral health. Gum disease is a risk factor for heart disease.
