It's possible to brush your teeth effectively with a manual toothbrush — but an electric toothbrush can be a great alternative to a manual toothbrush, especially if you have arthritis or other conditions that make it difficult to brush well. The bristle movement of an electric toothbrush might even help you remove more plaque from your teeth and improve your gum health.
If you choose to invest in an electric toothbrush, make sure the toothbrush is comfortable to hold and easy to use. Your dentist might suggest a model with a rotating-oscillating head. Other specific features — such as adjustable power levels, timers and rechargeable batteries — are up to you.
Whether you choose an electric toothbrush or a manual toothbrush, what's most important is daily brushing and flossing.
