How to choose an electric toothbrush that suits your daily routine

An electric toothbrush can help you establish a regular brushing routine, but the promises printed on the packaging aren't enough to make the right choice. An impressive battery life might hide an inconvenient charger, while a high speed doesn't necessarily guarantee comfortable brushing, especially if you have sensitive gums.

Here are the criteria to consider before buying, along with a selection of models suited to different needs.

Common pitfalls to avoid before buying

1. Confusing the number of movements with cleaning quality

A sonic toothbrush capable of tens of thousands of movements per minute might seem more effective. However, your brushing technique, the shape of the brush head and how consistently you brush remain the most important factors. A high number doesn't tell you much about comfort, noise level or ease of control.

2. Overlooking the pressure sensor

Brushing too hard can make the experience uncomfortable and irritate your gums. Without a pressure sensor, it's up to you to correct your own technique. For those with sensitive teeth or gums, a light, sound or vibration signal can serve as a useful guide, though it doesn't replace professional dental advice.

3. Underestimating the cost of replacement heads

A rechargeable toothbrush may come with several accessories, but you also need to check the availability and compatibility of replacement heads. Manufacturers generally recommend replacing them regularly, often every three months or so, or sooner if the bristles become worn. The real cost over time therefore depends on the price of refills too.

Technical specifications to check

Technology and brush head shape

Sonic models produce rapid vibrations and are typically moved from tooth to tooth, without requiring a vigorous scrubbing motion. Rotating or oscillating models use a round head and a more targeted mechanical movement. The sensation in your mouth differs, so it's best to choose based on your comfort and habits.

Timer and zone guidance

A two-minute timer, combined with a 30-second reminder, helps you distribute brushing time evenly across the four zones of your mouth. This feature is particularly useful if you tend to cut your brushing short or, on the other hand, spend too long on the most visible teeth.

Battery life, water resistance and charging

For daily use, make sure to check:

  • the advertised battery life, expressed in days or months depending on your expected usage frequency;
  • whether it comes with a charging stand, USB cable or magnetic charging system;
  • the charger's electrical compatibility if you plan to travel;
  • the water resistance rating, such as IPX7, bearing in mind that the charging stand and adapter are generally not waterproof;
  • whether a travel case is included if you're often on the move.

A long battery life means you can charge less often, but it doesn't remove the need to check the availability of the cable and compatible heads.

Daily use and maintenance

To get the most out of your rechargeable toothbrush, a few simple steps are all it takes:

  1. Place the brush head against your teeth before turning the device on to minimise splashing.
  2. Guide the brush slowly along the gum line, without replicating the vigorous motion of a manual toothbrush.
  3. Rinse the brush head after each use, then leave it to air dry.
  4. Clean the handle according to the manufacturer's instructions.
  5. Replace the brush head as soon as the bristles become deformed or according to the recommended schedule.
  6. Never immerse the charger in water, even if the handle has an IPX7 rating.

FAQ about electric toothbrushes

How long should you use an electric toothbrush?

Models with a timer are generally set for a two-minute session, with reminders for each zone. The exact duration should follow the manufacturer's instructions and your own brushing habits.

How long does a rechargeable toothbrush last?

It depends on the battery, how often you use it, how well you maintain it and the availability of compatible brush heads. Before buying, check the warranty period, the accessories included and the charging conditions.

Is an electric toothbrush more expensive to use?

The purchase price is only part of the overall cost. You also need to factor in replacement heads, the electricity used and, for some models, specific accessories. A long battery life can reduce how often you need to charge, but it doesn't eliminate the need to replace the brush heads periodically.
