TAKEAWAYS
- Mechanism of Action: Sonic toothbrushes vibrate at high speeds to move toothpaste and water into tight spaces (non-contact cleaning); Rotary toothbrushes use a spinning or oscillating head to physically sweep away debris.
- Brushing Speed: Sonic brushes typically range from 31,000 to 62,000 strokes per minute, while rotary models usually operate at much lower speeds, around 2,500 to 8,000 rotations per minute, often supplemented by “pulsations.”
- Brush Head Shape: Sonic models usually feature a standard oval shape similar to a manual toothbrush; Rotary models use a small, circular head designed to cup and clean one tooth at a time.
- User Technique: With a sonic brush, you use a traditional manual brushing motion; with a rotary brush, you simply move the spinning head from tooth to tooth, letting the motor do the scrubbing.
- Gum Sensitivity: Sonic technology is widely considered gentler for sensitive gums and receding gum lines due to the vibrating “massage” effect rather than mechanical friction.
- Plaque Removal Style: Studies suggest both are effective, but rotary brushes excel at mechanical plaque removal in hard-to-reach molars, while sonic brushes are superior at cleaning the interdental spaces via fluid dynamics.
- Noise and Feel: Sonic brushes produce a high-pitched hum and a “tingling” sensation; rotary brushes typically have a louder, mechanical motor sound and a more vigorous physical vibration.
Electric toothbrushes have gradually replaced traditional toothbrushes with their own advantages and become an essential product for people to maintain their own oral health.
The electric toothbrush rotates the brush head at a high speed according to the rapid rotation or vibration of the motor core, so as to achieve the effect of deep cleaning. However, electric toothbrushes are divided into sonic electric toothbrushes and rotary electric toothbrushes. What is the difference between the two?
1. Sonic electric toothbrush
Sonic electric toothbrush refers to an electric toothbrush whose bristles vibration frequency is almost the same as the frequency of sonic waves, so it is also called a sonic vibration toothbrush. The bristles with a frequency similar to the sound wave vibration can be used to quickly move to achieve nearly a hundred times the super cleaning effect of a traditional toothbrush.
There is an electric-driven vibration motor inside the toothbrush, which can make the brush head produce high-frequency vibration in the vertical direction, but the swing amplitude is extremely small, about 5 mm up and down. When brushing, the vibrating brush head can efficiently complete the brushing action, allowing the toothpaste and water in the oral cavity to mix to produce a large number of tiny bubbles, deep into the teeth to clean dirt.
Sonic electric toothbrush‘s sonic technology can combine with the high-frequency vibration of the toothbrush head to produce a wave of cleaning power. Compared with traditional toothbrushes, sonic electric toothbrushes are more suitable for scientifically brushing up and down. Effectively remove plaque on teeth and ensure healthy and white teeth.
2. Rotating electric toothbrush
Rotating electric toothbrush is a kind of electric toothbrush that drives the round brush head to rotate through the operation of the internal motor of the toothbrush. The rotation of the toothbrush increases the friction of the toothbrush against the teeth. The rotating electric toothbrush has a simple working principle and is cheaper than a sonic toothbrush.
However, rotary electric toothbrushes are more likely to damage the gums than sonic electric toothbrushes. But also because of its strong friction, the toothbrush will be able to clean about 38% more plaque.
Electric toothbrushes, whether sonic or rotary, have better cleaning power than traditional toothbrushes, but sonic electric toothbrushes are still better on the market today.
3. Private Label Your Branded Electric Toothbrushes
When looking to your manufacturers of electric toothbrush, remember to see whether they can meet your private label requirements. This including the pre-design models, packaging options, private molding and even more. Ask Cinoll for a quick quotation and advice on manufacturing for your electric toothbrushes!
