Most refills focus on one job - plaque, stains, or gum care. The A3 All-in-One has bristles arranged for all three in the same brushing session. Multi-angle bristles across the head keep contact even if your brushing technique is uneven, so plaque comes away from molars and front teeth alike. A cluster of triangular bristles in the centre works on surface stains from coffee, tea, and red wine, lifting them over a few days of regular use.
Longer side bristles reach the gumline and sweep along it while you focus on the teeth, leaving gums feeling cleaner and less irritated after a few weeks. Softer bristle stiffness feels gentle on sensitive areas without losing the feel of a thorough clean. That combined coverage is what separates the A3 from a plaque-only refill - fewer compromises across the routine.
Blue indicator bristles fade to white with use, and BrushSync technology lets you know when to change the brush head via the Sonicare app.
How to Use:
- Click the old brush head off your toothbrush
- Push the new brush head onto the top of the handle until it clicks into place
- Brush for two minutes daily (30 seconds each quarter of your mouth)
- Rinse the brush head and handle after use
- Replace the brush head every three months, or when bristles start to fray
