UniTooth: The World’s First Counter-Rotating Toothbrush

All Projects, Newest Arrivals, Recommended Projects

Dual counter-rotating heads automate the perfect Bass Method. IPX8. 120-day battery.

You’ve been brushing wrong your entire life.

90% of people scrub side to side. It damages enamel, pushes gums back, and misses the plaque where disease starts.

Dentists have recommended the Bass Method since 1954 — a gentle 45° sweep along the gumline. But almost nobody can do it correctly by hand.

UniTooth does it for you.

The foundational paper that established the Bass Method — the #1 dentist-recommended brushing technique for 70 years.

Peer-reviewed evidence that aggressive brushing causes enamel wear, gum recession, and dentine hypersensitivity.

The gold-standard meta-analysis: 56 randomized controlled trials, 5,068 participants. Conclusion: rotation-oscillation is superior to manual brushing.

Backed by Science. Not Marketing.

We didn’t just build another electric toothbrush. We rethought how brushing should work — from the physics of the brush head to the science behind every stroke.

  • Counter-Rotation Dual heads, balanced power → Two brush heads spin toward each other, creating a balanced clamping effect that locks bristles onto every tooth surface. No bounce. No wasted motion.
  • Bass Method 45° precision cleaning → Engineered to maintain the optimal 45° angle automatically — replicating the dentist-recommended sweeping technique that 90% of people can’t do by hand.
  • 4-Month Battery Life 2,600mAh → One USB-C charge delivers up to 120 days of twice-daily brushing. That’s four months without reaching for a cable.
  • IPX8 Waterproof Fully submersible → Rated beyond industry standard. Shower with it, rinse it under the tap, drop it in the sink — it keeps running.
  • 600g·cm Torque Never stalls under pressure → Professional-grade motor power that maintains constant speed from front incisors to back molars, no matter how hard you press.
  • Universal Design Adult & Kids heads → Magnetic snap-on heads swap in seconds. One premium handle, perfectly sized bristles for every member of the family.

Traditional single-head brushes create unbalanced centrifugal force. The bristles bounce and skip across the tooth surface, reducing contact time and leaving plaque behind.

UniTooth’s dual heads rotate toward each other, generating a balanced “clamping” effect that locks bristles onto every surface. The result: maximum plaque removal with zero wasted motion.

The Modified Bass Technique is the #1 brushing method recommended by dental professionals worldwide. It requires maintaining a precise 45° angle while performing short vertical strokes along the gumline — a skill that takes weeks to learn and is nearly impossible to maintain consistently. UniTooth’s dual counter-rotating heads are engineered to replicate this exact motion automatically.

The dual brush heads embrace each tooth from both sides, sweeping in the natural direction of tooth growth. This “clamping” contact ensures bristles reach deep into the gingival sulcus — the critical 2-3mm pocket where 80% of oral disease originates.

From above, you can see how the dual heads conform to the contour of each tooth. The counter-rotating motion creates a gentle yet thorough sweeping action across the entire biting surface — something a single-head brush simply cannot achieve.

The side view reveals how UniTooth’s bristles wrap around the lateral surfaces of each tooth, reaching the interproximal spaces that flat brush heads often miss. Every angle is covered in a single pass.

This anatomical cross-section shows the bristles entering the gingival sulcus at the optimal 45° angle. The sweeping rotation moves from gum to tooth tip, dislodging plaque and bacteria from below the gumline without causing tissue trauma.

Most electric toothbrushes need charging every 1–2 weeks. UniTooth packs a massive 2,600mAh lithium-ion battery that delivers up to 120 days of brushing power on a single USB-C charge. That’s four months of twice-daily use — no charging cables, no anxiety, no interruptions.

UniTooth is rated IPX8 — fully submersible beyond 1 meter. While most competitors stop at IPX7 (splash-proof), UniTooth is built to handle full immersion. Use it in the shower, rinse it under the tap, drop it in the sink. It keeps running.

Cheap electric toothbrushes slow down the moment you press against your teeth. UniTooth delivers 600g·cm of professional-grade torque — constant rotational power that won’t stall under pressure. Every tooth gets the same thorough clean, from front incisors to back molars.

Why buy two expensive electric toothbrushes when one does it all? UniTooth features interchangeable Adult and Kids brush heads that snap on magnetically in seconds. Same premium handle, same powerful motor — perfectly sized bristles for every member of the family.
