Comparing electric toothbrushes: sonic power versus oscillating-rotating | Dentistry33? ›

Electric rotating-oscillating toothbrushes come with lower power than sonic toothbrushes, but due to the rotating head you can find them quite powerful in removing the plaque off your teeth. Sonic toothbrushes, on the other hand, are considered much more effective thanks to the high level of vibrations they provide.

The winner is: sonic toothbrush.

An electric toothbrush can increase your number of brushstrokes to around 2,500 to 7,000 strokes per minute. However, the sonic toothbrush boasts a whopping 30,000 brush strokes per minute, making it an excellent choice for those with limited mobility.

But what's the difference between these two? Regular electric toothbrushes have rotating heads that can spin several thousand times per minute, but sonic toothbrushes spin tens of thousands of times per minute, which can give you a cleaner smile in a shorter period of time.

Some have a travel case and multiple heads. The ExpertClean 7300 has a replacement head, while the DiamondClean Smart 9300 has a plaque control brush head, a white brush head, and a gum health brush head. Not all heads are compatible with all models, so check compatibility before buying replacements.

However sonic brushes do have one major drawback; they tend to be quite expensive compared to both manual and electric versions making them cost-prohibitive for some users with tighter budgets who still want a quality brush for cleaning their teeth thoroughly each day!

Sonicare's heads are large and flat compared to Oral-B's small round brushes, and they're long-lasting, according to Wellspring Dental dentist Mandy Nebel, who prefers Sonicare over other brands. This specific model — one of two from the brand accepted by the ADA — is a more entry-level Sonicare.

Like rotating oscillating toothbrushes, Sonic electric toothbrushes include spinning and oscillating features to clear plaque, but they also move much faster. Compared to an oscillating toothbrush's limit of 7500 rotations per minute, Sonic brushes have an average of 30,000 brushes each minute.

The Sonic Brush utilizes a dentist-recommended toothbrushing method, ensuring an effective and thorough dental-grade clean every day. Experience unparalleled performance and maintain optimal oral hygiene with ease.

Sonic toothbrushes combine physical movement along with sound vibrations, whereas ultrasonic toothbrushes rely solely on high-intensity sonic vibrations.

What is the difference between ultrasonic and ionic toothbrushes? ›

Ultrasonic means a brush action where the bristles flutter at ultrasonic frequencies (greater than 20 kilohertz). Ionic refers to a brush that gives an electric charge to the tooth surface to disrupt the attachment of dental plaque.

According to a NCBI research-based article where Sonicare and Oral-B electric toothbrushes were compared, it stated, “Overall, this study demonstrates that long-term use of these two electric toothbrushes improves periodontal health in adult periodontitis patients, and that the Sonicare brush is superior to the Braun ( ...

Plus, an Oral-B electric toothbrush like the Oral-B Pro 1000 even removes 26% more plaque than Sonicare DiamondClean* and 100% more plaque than a regular manual toothbrush.

The circular movement of rotating brush heads allows for precise cleaning around each tooth, proving effective against plaque in those hard-to-reach areas.

Oscillating-rotating: This kind of toothbrush has a small, round brush head that oscillates back and forth in a circular motion to help remove plaque. A smaller brush head can be very good for cleaning the hard-to-reach areas of your mouth.

Benefits of an Electric Toothbrush

Removes more plaque –electric toothbrushes remove up to 70% more plaque than manual toothbrushes in hard-to-reach places*. Good for your gums – an 11-year study of electric vs. manual toothbrush use found that electric toothbrushes resulted in 22% less gum recession.

The rotary or sonic type causes you to pay close attention to what you are doing. This is good. However, you can also do this with a manual toothbrush. None of these cleans between the teeth, which is where 85% of the contact between teeth and gums occurs.
