Oral-B Smart 4 4500 - Electric Toothbrush with App - Black

The Oral-B Smart 4 4500 is built around a round brush head that performs a 3D cleaning action – and that defines its approach. Its technical foundation is a combination of rotation and oscillation at 9,900 movements per minute. As a 'smart' model, it can connect to a mobile app for feedback, but it also works completely on its own. The handle is slim, with physical buttons for control.

The round brush head is classic Oral-B design. Its 3D cleaning technology pairs rotation with pulsating vibrations, running at a brisk 9,900 movements per minute. In practice, this means a mechanical, plaque-focused clean. You can switch between three cleaning modes for different intensities. A memory function automatically starts the brush on your last used setting.

Under the hood

• Cleaning technology – 3D: rotating and oscillating.
• Movements per minute – 9,900.
• Number of speeds – 3.
• Pressure sensor – Yes, with a light and vibration alert for excessive pressure.
• Timer – A professional 2-minute timer with a signal every 30 seconds.
• Whitening function – Present, focused on removing surface stains.

The 'smart' label comes from its ability to pair with the Oral-B smartphone app. This provides brushing analysis and guidance, offering real-time feedback on your technique and coverage. The toothbrush itself doesn't need Bluetooth or Wi-Fi for this; the connection works differently. One detail: to access the app's full features, you must create an account, which involves sharing user data. It's compatible with Android and iOS. Without the app or a phone nearby, the brush operates fully using its built-in sensors and timer.

The handle has a black finish and a slim profile. Its brush heads are of medium hardness. A battery indicator on the handle shows charge status. With a battery life of 50 minutes of brushing, you get about two weeks of use from a charge with twice-daily, two-minute sessions. It charges via the included charging station in roughly 12 minutes (0.20 hours). The brush is suitable for adults and children aged 10 and over, but not for primary teeth.

This is a toothbrush for anyone who wants structure in their routine. The timer with a signal every 30 seconds guides you to brush each quadrant of your mouth. Its pressure sensor is a practical feature to protect sensitive gums from a common electric brushing mistake. The smart app features add an optional layer of insight but aren't required for basic use. The brush cannot connect to the internet by itself and doesn't need any paid subscriptions. The round brush head is compatible with a wide range of Oral-B replacements, like Cross Action or 3D White. It comes with a manufacturer's warranty of 2 years.

The packaging weighs 556 grams and measures 251 x 175 x 100 mm.
