One of the most common questions that I get asked is “is it worth it to invest in an electric toothbrush?” The answer that I give is that it is a matter of personal preference. A number of different factors must be considered. Cost is probably top on the list. An electric toothbrush will cost significantly more than a manual one. And the brush portion of the electric model will need to be replaced jut as frequently as the manual variety, and usually at a higher cost. Is an electric toothbrush more effective at cleaning the tooth surfaces? Many studies have shown that both manual and electric toothbrushes perform their job equally well. The main thing is that if it is easier for someone to clean their teeth with an electric toothbrush and they can afford the extra expense, then that is what I would recommend that they use. For people with manual dexterity problems, such as arthritis sufferers, an electric toothbrush can be a great help in cleaning one’s teeth. When buying an electric toothbrush, always look for the American Dental Association seal of approval. The ADA does stringent, independent testing so you can be assured that the manufacturers claims have been verified.
