Oral-B iO3

Why it's our Endgame pick

• The entry model of Oral-B's iO range, which TechRadar's 2026 guide names its best premium pick.
• Oral-B's own comparison lists no cleaning difference from the ₹10,190 iO9, which adds a screen, app tracking and more modes.
• Has the iO's round head, a pressure sensor and 3 modes; dentists quoted by Wirecutter say you don't need the costlier smart brushes.

Watch out: iO refill heads cost more than standard Oral-B heads.
