Choosing an electric toothbrush: a practical buying guide for everyday use and travel

An electric toothbrush can be useful if you want to keep track of how long you brush, apply less pressure or avoid being without a charging cable when you’re away from home. However, you may end up paying for features you hardly ever use. A screen, app or wide choice of brushing modes may sound appealing, but they don’t automatically make a toothbrush easier to use or right for your teeth.

Focus on specifications you can check. These are some common pitfalls to watch out for when comparing a sonic electric toothbrush or rechargeable toothbrush.

Three pitfalls to avoid when buying an electric toothbrush

1. Long battery life without clear information about charging

A battery that lasts for months is convenient, but check how the manufacturer measured this. The number of brushing sessions, the mode selected and the charging time can all affect how long the battery lasts in practice. Also check the connection. USB-C is handy for travel, while some models require a dedicated charging stand.

2. Lots of brushing modes you won’t use

A toothbrush with several brushing modes can be useful if you’ll actually switch between them, for example between everyday cleaning and a gentler mode. For many people, an everyday mode, a sensitive mode and a reliable timer are enough. Extra modes can mainly add to the price and make the controls less straightforward.

3. Marketing claims about cleaning or whitening

Claims such as “removes up to three times more plaque” or “whiter teeth” are claims made by the brand. According to Philips’ own research, some Sonicare models can achieve these results under the conditions used by the brand. Don’t take this as a universal guarantee for every user. Good brushing technique, a suitable brush head and regular replacement remain important.

Which specifications should you check?

Timer and brushing guidance

A toothbrush with a timer helps you stick to the recommended brushing time. Look for two features:

  • an automatic shut-off after around two minutes;
  • a signal to switch to a different area every 30 seconds.

Some models only give a signal at the end, while others also guide you through each quadrant. The second option is often easier to follow if you’re new to electric toothbrushes.

Pressure sensor and sensitive teeth

An electric toothbrush with a pressure sensor warns you when you’re pressing too hard. This can be useful if you’re used to brushing firmly with a manual toothbrush. A pressure sensor is no substitute for personal advice from a dentist or dental hygienist.

If you’re looking for an electric toothbrush for sensitive teeth, consider a soft brush head, a Sensitive mode and adjustable intensity. According to the product description, the Philips Sonicare 6100 has a Sensitive mode, three intensity levels and a warning for excessive pressure. Stop using it and ask a dentist for advice if pain or irritation persists.

Battery, water resistance and travel case

When choosing an electric toothbrush for travel, these features are worth considering:

  • battery life on a full charge;
  • type of charging cable or charging stand;
  • whether it comes with a sturdy travel case;
  • protection for the charging port;
  • cleaning and drying instructions.

A water-resistant handle doesn’t mean you can put the charger in water. Always check the instructions and only connect a USB cable when the charging port is dry.

Use and care

A rechargeable toothbrush stays practical for longer when you look after it properly:

  1. Rinse the brush head after every use and leave it to dry upright.
  2. Don’t leave a wet toothbrush sealed in its travel case for long periods.
  3. Check the bristles before use.
  4. Replace the brush head about every three months, or sooner if the bristles are frayed.
  5. Only connect a USB-C cable or charging stand when the port is dry.
  6. If you have sensitive teeth, use a low intensity and apply very little pressure.

Before buying, also check that replacement brush heads are easy to find. The price of the handle is only part of the overall cost.

Frequently asked questions

Is a sonic electric toothbrush suitable for beginners?

Yes, as long as you start gently and don’t press the brush hard against your teeth. Ideally, choose a model with a timer and, if you find it helpful, a pressure sensor. Let the brush do the work and move it slowly along your teeth and gumline.

How long does an electric toothbrush last?

Battery life per charge varies considerably by model: product specifications range from around two weeks to several months. Overall lifespan depends on the battery, charging habits, wear and care. Brush heads usually need replacing about every three months.

How much does it cost to use an electric toothbrush?

As well as the purchase price, you’ll pay for replacement brush heads and electricity. A small rechargeable toothbrush usually uses very little electricity. Before you order, compare the price and availability of compatible brush heads.
