Choosing an electric toothbrush: a practical buying guide for adults and children

An electric toothbrush can be a useful addition to your daily oral care routine, but not every feature is beneficial for everyone. A high vibration speed, a comprehensive app or a wide range of brushing modes may sound appealing, but that does not automatically mean the device suits your routine.

Pay particular attention to three common pitfalls:

1. Focusing too much on marketing claims
   Brands sometimes compare their models with a manual toothbrush and quote large percentages. According to Oral-B’s own research, various iO models make claims about plaque removal and gum health after a certain period of use. Such results are not a universal guarantee. Also look at verifiable features such as a timer, pressure sensor, battery type and the brush heads included.

2. A pressure sensor that only sounds useful on paper
   Not every sensor provides the same feedback. A light, vibration or automatic reduction in speed only works well if you actually respond while brushing. For sensitive teeth or gums, a gentle mode is at least as important.

3. Forgetting to check replacement brush heads
   The purchase price is only part of the overall cost. Check in advance which type of brush head is required, how many are included and how often the manufacturer recommends replacing them. Product information for several models mentions replacement after approximately three months, or sooner if the bristles are worn.

Which features should you check?

1. Timer and brushing guidance

A toothbrush with a timer helps you stick to the recommended brushing time of two minutes. An interval signal every 30 seconds divides your mouth into four zones. This is practical if you brush quickly or tend to miss certain areas.

A simple timer is sufficient for many users. An electric toothbrush with an app may also offer a map of your mouth, brushing statistics or reminders. These features are particularly useful if you like receiving feedback and genuinely use the app regularly.

2. Pressure sensor and brushing modes

An electric toothbrush with a pressure sensor can warn you when you are pressing too hard. Feedback varies by model:

• Oral-B iO2 gives a red signal and reduces the speed when too much pressure is applied, according to the product description.
• Oral-B iO5 and iO6 indicate whether the pressure is too high, too low or appropriate.
• Philips Sonicare 7100 uses light and vibration feedback, according to the product information.

Also consider the number of modes. A toothbrush with multiple brushing modes may offer daily cleaning, sensitive brushing, intensive cleaning or whitening. More modes are not automatically necessary. For many adults, daily cleaning and sensitive brushing are the most important options.

3. Battery, charging and water resistance

A rechargeable toothbrush usually works with a charging stand, USB-C or another included charger. Check:

• the stated battery life;
• the charging time;
• whether a travel case is included;
• whether the charging port needs to be dry;
• which water-resistance rating is specified.

An IPX7 or IPX8 rating refers to the device’s water resistance under certain conditions, but it does not mean that you may bring the charger into contact with water. Charging stands should be positioned somewhere dry and safe. Do not use a damaged handle, cable or brush head.

Practical buying tips for home

• For adults: choose at least a timer and a gentle or sensitive mode. An Oral-B electric toothbrush with a round head works differently from a sonic toothbrush such as a Philips Sonicare. The difference in technology is mainly a matter of preference and getting used to it.
• For sensitive teeth or gums: start with the lowest intensity and use a suitable soft brush head. If symptoms persist or are particularly noticeable, seeking advice from a dentist is wiser than switching between increasingly powerful modes.
• For families: check that each family member has their own handle or brush head. Do not share brush heads.
• For travelling: consider battery life, charging type and a travel case. A USB-C model can be useful if you already have suitable charging equipment, but always check that the charging port is dry.

Frequently asked questions about electric toothbrushes

How long does an electric toothbrush last?

Lifespan varies depending on the brand, battery and usage. The statutory guarantee in the EU is at least two years, but that does not promise that the battery will retain the same capacity afterwards. Clean the handle according to the instructions, avoid damaging the charger and replace brush heads on time.

How much does it cost to use an electric toothbrush?

In addition to the device, you pay for electricity and replacement brush heads. The electricity consumption of a rechargeable toothbrush is generally a smaller part of the cost than the brush heads. Therefore, compare the price and availability of suitable refills in particular.

Is a sonic toothbrush suitable for children?

That depends on the age recommendation, brush head and intensity. Choose a model specifically designed for children, such as an electric children’s toothbrush with soft bristles. Children should be supervised while using it in accordance with the product instructions, particularly at a younger age.
