Best Electric Toothbrush Replacement Brush Heads UK (2026)
Medically reviewed by Dr Zaeem Jafri BDS on 13th February 2026
So you’ve already got your electric toothbrush sorted, but now you’re looking to take care of it over the next year, keep it pristine and ensure it serves you properly every time you use it. Keeping your electric toothbrush in peak condition is just as important as choosing the right handle. Dentists recommend regularly swapping your brush head every three months helps reduce plaque build-up and protect gums, and subscribing to regular replacements can take the guesswork out of oral care. In the UK, you can choose from a range of excellent replacement heads and subscriptions that fit popular toothbrush brands like Oral-B and Philips Sonicare, and remove a lot of the friction from memorising when you need to get a new one.
Replacing brush heads will mean the brush’s bristles remain ready for action every time you use it, and not keeping on top of this can result in sub-par performances and actually damage your gums. Signing up for monthly replacements will reduce costs and keep you fully updated.

How we test the best replacement brush heads
All the brushes featured in this article have been tried and tested by Dr Zaeem Jafri, our founder and expert dentist. And are a result of personal opinion.
They have been selected because of their price point, but also because they have some of the best features for getting the best results. Each will have its own merits and positives, so use your own research to help inform your own decision to find the best toothbrush for you.
How To Select The Right Replacement Electric Toothbrush Head For Your Toothbrush?
It should be obvious, but buying the right replacement brush head for your toothbrush means sticking to the brand of the brush you own. If you have an Oral-B iO5, for example, an Oral-B brush head will be compatible, but not a Philips one. However, there are different types of brush head depending on your need or style. Some brush heads will have longer necks, different shaped bristles or different designs overall. The key here is to find a brush that fits with your brand, will do the job specifically that you want to do, and has a subscription offer so you can sign up, pay and simply wait for the new brushes to arrive when you need them.

A subscription ensures you always brush with heads that are fresh and effective, which is key for both plaque control and gum health.
Tips for Choosing the Right Replacement Heads
Match to your handle: Always check that the head you choose is compatible with your specific electric toothbrush model. Oral-B and Philips both have different head types depending on series and technology.
Brush type matters: Some heads focus on gentle care for sensitive mouths, while others target whitening or plaque removal. Think about your priorities when selecting replacements.
Replace regularly: Most dentists recommend swapping brush heads every three months to maintain optimal cleaning performance.
Choosing the right replacement heads keeps your electric toothbrush performing at its best. Whether you favour a subscription for automatic deliveries or prefer to buy packs from Boots or Amazon, these options represent some of the best choices available in the UK today.
