Our research has discovered that electric toothbrush heads are on sale so often, you need never pay full price. We reveal what you should pay for a toothbrush head, and where you’ve likely to find them on sale.
Electric toothbrush heads at full price can be up to £18 a pack, but we found they’re on offer so often you should really only buy them when they’re on sale at £12 or less.
We used an independent shopping website to track individual prices for eight different toothbrush heads over six months, and discovered that Boots and Asda had their Colgate and Oral B brush heads on offer for at least half the time – and often more than this.
But how do you know which electric toothbrush to buy in the first place? We put electric toothbrushes from big brands like Colgate, Phillips and Oral B through their paces in our rigorous lab tests.
Our results reveal the high-scorers that will leave you with sparkling pearly whites, and duds that will spend more time recharging than blasting plaque.

Oral B toothbrush heads on offer at Asda and Boots
The Oral B replacement heads that we looked at were on sale for 14 out of 27 weeks at Boots. While Asda had all its Oral B replacement heads on sale for at least half the time.
As you need to replace your electric toothbrush heads every four months, we’d strongly recommend only buying them when they’re on offer.
But are Oral B brushes any good? We’ve put 11 different types of Oral B electric toothbrushes through our tough tests, ranging from a £17 model to one that will set you back £100. Is it worth paying more? See all of our Oral B electric toothbush reviews.
Short stints at full price
We also found that when toothbrush heads are not on sale, it’s only for short stints of three to four weeks. Then they go on sale again.
So you shouldn’t have to wait long to catch the brushes you want at a reduced price.
Although Phillips ProResults brush heads were on sale less often, you can still avoid paying full price. See our graphic, above right, for details. And to see how big brand Phillips fares in our testing, check out all of our Phillips electric toothbrush reviews.
