SURI Sonic Electric Toothbrush Replacement Heads — Winter Fern Pack of 3, Plant-Based Recyclable Medium-Soft

These replacement heads pair exclusively with SURI sonic toothbrush handles and swap in quickly for continued sonic cleaning without replacing the entire brush. Constructed from bio-based materials derived from cornstarch and castor oil, the heads and bristles are designed for recycling through SURI's free U.S. recycling program. The slim profile and mixed-bristle arrangement aim to reach between teeth and along the gumline while offering a medium-soft brushing experience.

How do these heads fit my SURI Sonic Toothbrush?

Each head is engineered to snap onto SURI sonic toothbrush handles, matching the brand’s attachment system and vibration pattern for a secure fit. They will not fit non-SURI electric toothbrush brands or generic snap-on systems.

• Compatible only with SURI Sonic Toothbrush handles
• Simple push-and-click replacement installation
• Designed to maintain proper brushing angle and contact
• Pack of 3 for staggered replacements

What makes the bristles plant-based and recyclable?

The brush head bodies and bristles use bio-derived feedstocks — primarily cornstarch and castor oil derivatives — instead of traditional petroleum plastics. SURI provides a U.S. recycling pathway for these materials so the used heads can be returned and processed instead of thrown away.

• Bristles crafted from bio-based polymers (cornstarch, castor oil derivatives)
• Head components designed for SURI’s free recycling program
• Less reliance on fossil-fuel plastics in construction
• Winter Fern color finish for an updated aesthetic

How do the bristle design and 3DWave shape affect cleaning?

The 3DWave bristle layout alternates firmer and softer tufts in a slim, contoured head that helps reach interdental spaces and follow tooth curves. While individual results vary, the mixed-bristle pattern is intended to dislodge surface debris and sweep along gum margins effectively with sonic motion.

• Alternating firm and soft bristles for targeted contact
• Slim head shape suited for hard-to-reach areas
• Optimized for plaque and food removal during sonic motion
• Medium-soft feel aimed at balance between comfort and effectiveness

How often should I replace each head and what comes in the pack?

The pack contains three Winter Fern replacement heads so you can rotate replacements over several months. Replacement frequency depends on use intensity and bristle wear; inspect bristles regularly and replace when they show fraying or reduced spring.

• Pack includes three SURI replacement heads (Winter Fern color)
• Recommended replacement aligned with visible wear or routine intervals
• Swap-in installation keeps your existing handle and electronics
• SURI’s recycling option available for used heads in the U.S.

Who this is for: These replacement heads are suited for SURI Sonic Toothbrush owners who want an eco-minded refill option with medium-soft bristles, a slim profile for easier interdental access, and a simple recycling route. Choose this pack if you prefer plant-based materials, need three replacement heads for regular rotation, and have a SURI sonic handle.
