Several studies have compared electric toothbrushes to traditional manual brushes. The results support the use of electric toothbrushes.
Many years ago electric toothbrushes were something of a gimmick. They vibrated at slow rate, and still required a brushing movement to work properly. Often intended for children they were given novelty cartoon designs, though they may have at least encouraged children to brush.
Modern toothbrushes are different. They have either oscillating heads that perform the brushing automatically, or they vibrate at ultrasonic frequencies that kill bacteria. According to long term studies these modern electric toothbrushes reduced plaque by 21% and gum disease by 6%, compared to manual toothbrushes.
Of course these types of studies cannot look at every aspect of dental health. It does not always pick up on the people who neglect to brush, or perhaps compare the people who floss to the people who don’t.
A toothbrush is only good if we use it.
One way of looking at the situation is to say that electric toothbrushes do the work for us. They achieve the same results, or better, then manual toothbrushes, but with less effort. Perhaps they achieve it in less time, though it is better to still brush for the full two minutes.
Electric toothbrushes are a great advantage for people with limited hand movements. people with arthritis or disabilities can use an electric toothbrush with minimal effort. This will produce better results than an manual toothbrush.
Teeth need to be flossed at least once per day, because no toothbrush can reach into the spaces between teeth. Mouthwash adds to the benefits of brushing and flossing.
The best toothbrush is the one used correctly twice every day, but if you find electric toothbrushes convenient, then by all means use them.
Brushing, flossing and use of mouthwash greatly reduces problems in teeth and gums. Talk to your dentist about the best options.
