Electric toothbrushes can be rather expensive items, but worth it if you value healthy teeth and gums.
The thing to know about them is that they are on sale very frequently, with discounts of 50% pretty much the norm. Across the sales, you can find deals along those lines, and also a few even better ones.

Buying an electric toothbrush: what you need to know
The electric toothbrush market is dominated by Oral B, with its rotary action brushes, and Philips with its Sonicare brushes, which use the power of vibration to dislodge debris and buff teeth and gums to a fine sheen.
They are both equally effective in our experience; it boils down to which you prefer. In our experience, Philips brushes tend to have slightly better battery life, and to be easier to keep clean, but those are pretty marginal gains.
Some of the more premium brushes you can buy from both brands now include Bluetooth connectivity and accompanying Android and iOS apps. Some – The Oral B Genius 9000 and Philips DiamondCare Smart for instance – even 'watch' you while you're brushing, to let you know that you've missed bits.
In our view, this technology is not yet fit for purpose, but don't let that put you off: the brushes with the 'smart' tech in are otherwise superb – the current state of the art, in fact.
One other thing to consider then buying a brush is how many replacement heads it comes with. The brush parts of the devices tend to wear out every 2-3 months and cost £2-£3 each to replace, so the more the merrier.
