We're Lab Verified.

Many “natural” toothbrushes still use synthetic nylon bristles on a bamboo handle. CERTA is different, our bristles are laboratory tested to verify they are made from real animal hair.

Why Switch to Natural Bristles

Trade harsh plastics for gentle, eco-friendly brushing.

Gently cleans without abrasion

Boar or horse bristles are softer than nylon, which reduces gum irritation.

Naturally antibacterial

Natural bristles and bamboo resist bacterial buildup better than synthetic brushes.

Fully biodegradable

Designed to decompose naturally, leaving no plastic waste behind.

Great at removing plaque

The natural texture and flexibility help sweep away plaque effectively.

Long-lasting & microplastic-free

Nylon bristles shed microplastics. Natural bristles don’t, but should be replaced every 2–3 months.
