Renew™ Replacement Sonic Brush Heads 4-Pack

Renew replacement brush heads restore the cleaning performance of your sonic toothbrush handle. Each pack includes four identical heads, enough to follow a quarterly replacement schedule across a full year of twice-daily brushing.

The heads use medium-soft nylon bristles arranged at a 45-degree angle to match the gumline positioning used by sonically vibrating brushes. They seat onto the handle's magnetic coupling with a soft click and are compatible exclusively with matching sonic handles from the same system, not with other sonic or electric brush systems.

Why it works

• Bristle density holds up through 62,000 vibrations per minute without fraying
• Bristles extend approximately 6 millimeters beyond the 8-millimeter head base for gumline reach
• Each pack includes a protective storage cap and mounting instructions

Specifications

• Pack size: 4 replacement heads
