Oral-B iO Ultimate Clean Brush Heads 4-Pack — Round Head + Micro-Vibrations for a Dentist-Clean Feel! $49.98 CAD (17% Off)

The Oral-B iO Ultimate Clean replacement brush heads come in a 4-pack at $49.98 CAD, down from $59.99 — about $11 off, or $12.50 per head. Brush heads are consumables you'll buy anyway, so stocking up during a discount just makes sense.

What sets iO heads apart from standard Oral-B refills is the combination of the classic round oscillating design with gentle micro-vibrations. The dual-length bristles work together — longer ones reach between teeth, while the high-density shorter bristles polish the tooth surface. The difference is something you feel when you run your tongue across your teeth after brushing.

Ranked #3 in replacement brush heads with over 11,000 reviews at 4.7 stars. Dentists recommend swapping brush heads every 3 months — once the bristles start to splay, cleaning effectiveness drops sharply, and it's not worth the few bucks you'd save by waiting. Four heads cover a full year.

Note: these are only compatible with the Oral-B iO series — they won't fit standard Oral-B handles.
