1. A superb electric toothbrush that won't break the bank (77%, Best Buy)

This toothbrush doesn't include all the latest bells and whistles that drive up the price, but it's great at removing plaque and costs a fraction of some rivals. 

It has several cleaning modes to choose from, plus all the other key features that make brushing simpler, including a two-minute timer, an interval timer and a battery-level indicator.

Which? senior editor Poppy Gaunt says: 'This electric toothbrush leaves my teeth feeling really clean, but the best part is how long the battery lasts – more than two months.'

2. An all-rounder toothpaste that gives a noticeable enhancement in whiteness (80%, Best Buy)

This whitening toothpaste combines low-abrasive cleaning agents with a natural mineral, making it safe for everyday use. 

Our lab tests confirmed it isn’t overly abrasive, so you'll get excellent cleaning and polishing without fear of damaging your enamel.

Which? consumer writer Natalie Turner says: 'I'm really fussy about the taste of my toothpaste and find a lot of options far too minty for my liking. I don't have that problem with this whitening toothpaste.'

3. Our highest-scoring electric toothbrush with features to help you develop better brushing habits (82%, Best Buy)

A key feature of this electric toothbrush is its ability to connect to a smartphone app. The toothbrush collects brushing-coverage data through AI sensors and syncs with the app via Bluetooth. 

The app also shows a 3D representation of a mouth with real-time tracking, so you can see exactly where you’re brushing.

Which? senior editor Alison Potter says: 'Like many, I had a tendency to brush much too hard, and it was really affecting my gums. My dentist noticed how much better my teeth and especially my gums look after six months of using this toothbrush.'

4. A standout electric toothbrush for kids aged six and up (79%, Best Buy)

This kids' electric toothbrush has three brushing modes (super sensitive, sensitive and daily clean).

It could be a good choice if you're switching from a manual brush or a younger child’s electric model, as starting on the lowest intensity will help them get used to the new vibrations.

Which? chief scientist Dr Steph Kipling says: 'This brush cleans my son's teeth really well, and it's quiet.'

5. A water flosser that impressed our entire test panel (93%, Best Buy)

This is the highest-scoring water flosser from our tests. It's great at cleaning and has a brilliant battery life.

It comes with an impressive array of attachments (five standard tips, one orthodontic tip, one periodontal tip, one tongue cleaner and one toothbrush tip) and has a textured pimple-like grip on the back to help you hold it when it gets wet.

Which? content lead Chad England says: 'I’ve been using a water flosser for years, and this Best Buy is the one I’ve stuck with the longest.'
