The ultrasound toothbrush has 84 million oscillations per minute. This toothbrush has a patented ultrasonic chip.

Nanobubbles and ultrasound technology works beneath the gums and removes stains and plaque on the tooth’s surface. Instead of scrubbing the surface of your teeth, the ultrasounds work without effort on the part of the user. They create millions of oscillations that turn toothpaste into bubbles filled with air.

What Could be Better?

The toothbrush vibrations are quite powerful. It can be overwhelming for beginners at first.

What is Ultrasonic, and How is the Technology Used in Your Toothbrush?

Ultrasonic toothbrushes use ultrasound technology to vibrate quickly. It produces a typical frequency that will be in the range of 1.6 MHz. That amount of sound frequency will vibrate at 96 million pulses per minute.

Imagine it’s like pressure waves that come from sound that you can barely hear. In a radio speaker, you can feel the vibrations of sound emanating from the device. That’s close to the same concept for ultrasound except the sound is just out of the range of human ears.

In your sonic or ultrasonic toothbrush, vibrations move the toothbrush in a way that uses pressure to remove food and plaque. Instead of using bristles to scrub and scrape plaque from the teeth, the vibrations are used for breaking apart plaque.

Manual toothbrushes are scraping and only going as fast as you can scrub. Electric toothbrushes with sonic or ultrasonic technology are far advanced, and will provide thousands of vibrations.

Differences Between Sonic and Ultrasonic

The motion from a sonic toothbrush has to be incredibly fast. It has to be so fast that it’ll produce a sound like a motor humming. It’ll be in range of a person’s hearing at 20Hz to 20,000 Hz. Sonic brushes will normally have movements that range in the thousands per minute. Usually between 24,000 and 48,000 depending on the manufacturer.

Ultrasonic toothbrush don’t use movement of the brush head or bristles to clean teeth. The ultrasonic sound frequency is what breaks up plaque and removes bacteria from your teeth. While sonic technology leaves off around 20,000 Hz, ultrasonic ranges from 20,000 Hz at the low end. It’s approximately 2,400,000 movements per minute.

It’s been proven in clinical studies that using sonic or ultrasonic technology will reduce plaque as well as increase saliva production. It’s another way to remove plaque and bacteria from the mouth.

Things you should remember when you buy an ultrasonic toothbrush

  • Brush Heads

The ultrasonic toothbrush should have replacement heads. You’ll want to be able to give everyone in the family their own brush head, too. You can do this by taking advantage of the color-coded brush heads that come with most ultrasonic toothbrushes. You’ll need to replace them every few months, so be sure that the replacement heads are easy to find.

  • Brushing Modes

With ultrasonic brushes, you’ll still need to worry about the focus of the brushing mode. If you want to focus on plaque or general cleaning, it should have a normal mode. Whitening and gum care are specialized modes that you’ll need to make sure are included. Not every toothbrush has all the brushing modes that should be the focus of your brushing.

  • Timers and Pacers

Two-minute timers and 30 second pacers will keep you on track. Dental professionals are firm about the time needed to brush each day. They recommend twice per day at 2 minutes per brushing session. To ensure that you are not skipping any teeth while brushing, the pacer will keep you on track.

  • Pressure Sensor

You don’t want to scrub the bristles on your teeth to remove food, plaque, or bacteria. Scrubbing and scraping will cause damage to your teeth and gums. It can actually cause receding gums in people who tend to brush aggressively. A pressure sensor will beep or slow down when someone presses too hard while brushing.

  • Battery Life

If you plan on traveling, you’ll want a toothbrush that lasts a long time with one charge. The ultrasonic toothbrush shouldn’t be abandoned because you’re going on vacation. That’s the time when you’ll need it the most. You’re going to be eating out more and need to brush your teeth thoroughly.

Brief History of the Ultrasonic Toothbrush

While many toothbrush advances happened a very long time ago, that’s not the case with the ultrasonic. It’s a type of toothbrush that was only introduced recently in terms of toothbrush technology. The first ultrasonic toothbrush was named the Ultima. It was patented in 1992.

In that first year, the FDA approved the ultrasonic toothbrush for use at home. At first, the Ultima only worked with ultrasonic pressure. Later, a motor was added to give it sonic vibration as well as ultrasonic. Robert T. Bock was the original inventor of the ultrasonic toothbrush. He eventually created new technology for a new ultrasonic toothbrush. This toothbrush became known as the Smilex Ultrasonic.

Bock was the originator of the technology, but many others have entered the market. Brands like Emmi-dent and Megasonex have ultrasonic toothbrushes, too.

Safety Issues in the Ultrasonic Toothbrush

Some users worry that ultrasonic technology might be dangerous. It’s a powerful vibration that people are afraid will cause dental issues. They’re worried fillings will be shaken loose, or the ultrasonic waves will cause internal issues with pacemakers and other medical devices.

Ultrasounds have been used in medicine for 50 years or so. It’s been studied in all that time. Ultrasounds are used for all types of medical procedures including taking pictures of babies in the womb.

The FDA started allowing the use of ultrasound in toothbrushes in 1992, and have had no reason to ever doubt that decision. A year later, The American Institute of Ultrasound in Medicine and NEMA helped the FDA develop new regulations that ensures the level of ultrasound isn’t harmful.

Frequently Asked Questions

What is the difference between sonic & ultrasonic toothbrush?
