Important Criteria when Buying an Electric Toothbrush
Several factors are crucial when buying an electric toothbrush. These include cleaning performance (e.g. through sonic or rotating technology), the number of cleaning modes, battery life, comfort (such as weight or volume) and additional functions such as pressure control, app connection or travel case. The price of replacement brushes also plays a role in the long term, as does availability in stores.
Those who have sensitive gums or are prone to gum problems should pay attention to particularly gentle models with a pressure sensor. Frequent travelers, in turn, benefit from robust travel cases with a charging function. Families with children can pay attention to models with color feedback and motivation.
Why Oral-B iO Series 9 is the Test Winner
The Oral-B iO Series 9 combines particularly effective cleaning performance with sophisticated design, state-of-the-art technology and intuitive operation. The innovative magnetic technology, which generates gentle micro-vibrations and thus enables thorough and gentle cleaning, is particularly noteworthy. The position detection via AI helps to ensure that no tooth surfaces are overlooked, while the color display provides feedback on the cleaning quality at all times.
The accessories are also first-class: A stylish travel case with USB charging function, a magnetic charger and a large selection of compatible attachments make the iO Series 9 the perfect choice for discerning users.
