Manual vs electric toothbrushes

With claims such as '100% plaque removal' and 'sonic technology' on their packaging, it's easy to assume electric toothbrushes clean better than regular ones.

Results from widespread clinical trials comparing the two types indicate that brushing with an electric model is slightly more likely to help your teeth and gums stay healthy in the long-term, compared with manual brushes.

But according to dental experts, how you brush is more important than what you brush with. To get the best clean from your electric or regular toothbrush, read our step-by-step how to brush with an electric toothbrush guide.

If you prefer to use a manual toothbrush, choose one with a comfortable handle and soft bristles – brushes with hard bristles can damage soft oral tissue.

Are electric toothbrushes better?

The key to great brushing is doing it gently and for long enough, and systematically cleaning the inside and outside surfaces of all of your teeth. This is where an electric toothbrush can have the edge over a manual one, as it can help you get an even clean across all of your mouth.

Most electric models have two-minute cleaning programmes as standard. These are invaluable for helping you make sure you spend enough time cleaning your teeth.

Some have interval timers to signal when to move on to the next section of teeth, and some have pressure sensors that indicate if you're brushing too hard.
