This Is What Happens When You Switch to an Electric Toothbrush, According to a Dentist

by | Jul 22, 2025 | Grooming

Electric toothbrushes have long been marketed as the gold standard for oral hygiene. But are they really better than a manual brush? With so many options on the market, from budget-friendly models to high-tech smart brushes, it’s natural to wonder if you’re missing out by sticking with a classic. We asked Dr Manrina Rhode. She is one of the UK’s leading cosmetic dentists. We wanted to know the real difference and what actually matters most when it comes to keeping your teeth clean and healthy.

Are Electric Toothbrushes Better?

While it might seem like a straightforward question, Dr Rhode says that ‘it’s not what you use but the way you use it.’

‘You can get a great clean from a manual toothbrush – but without added features like a built-in timer, people often rush their brushing. As a result, they fall short of the full two-minute recommendation.’ However, tools can make a difference in helping us build better habits.

Do Dentists Recommend Using an Electric Toothbrush?

In short, yes – as long as it’s used correctly.

‘We recommend a good rechargeable electric toothbrush with a 30-second timer and an automatic switch-off after two minutes,’ says Dr Rhode. This helps guide your brushing routine. You spend an equal amount of time on each part of the mouth – 30 seconds on each quadrant. You want to clean the outer gum margin, the inner gum margin, and the biting surface of each tooth systematically.’

She emphasises that technique matters even more than the tool. ‘It’s important not to “brush” in the traditional sense with an electric toothbrush,’ she adds. ‘You should gently hold the brush over each tooth and let the bristles and vibrations do the work. Otherwise, you risk over-brushing and damaging the gums.’
