The Oral-B iO5 combines advanced brushing tech with a sleek, user-friendly design to deliver a noticeably thorough clean.

It uses a dentist-inspired round brush head with micro-vibrating bristles to remove plaque effectively while remaining gentle on gums.

A built-in Smart Pressure Sensor lights up red when you press too hard and green when you’re applying the ideal pressure, helping to prevent over-brushing and gum irritation.

It also connects via Bluetooth to the Oral-B app, which provides real-time feedback, progress tracking and personalised coaching to improve technique.

Battery life lasts around 10 to 12 days from a full charge, and the handle is compatible with all Oral-B iO brush heads. The package typically includes a travel case, charger and one replacement head.

We could all do more to protect and clean our teeth, and getting the Oral-B iO5 is a great way to be proactive and keep your teeth and gums healthy for years.
