The iO2 electric toothbrush combines gentle micro-vibrations with a unique dentist-inspired round brush head for a purifying feel of a professional clean. This toothbrush offers 100% cleaner teeth than a regular manual toothbrush with Oral-B’s iO Technology, being tough on plaque and gentle on gums. It is designed for an easy switch to electric brushes with only one touch button, quiet sound, and long-lasting battery. Protect your gums with the automatic gum pressure sensor that slows down speed and signals red when you brush too hard. Easily choose your perfect clean with 3 quiet intensity levels: extra-gentle, gentle, daily clean. Brush for the dentist-recommended time with the 2-minute brush timer that alerts you every 30 seconds to change your brushing zone. Replace your Oral-B iO toothbrush head every 3 months for the best results. Please note: This item includes a UK 2-pin charger, Adapter not included.
