In the world of today, technology is advancing faster than most of us can comprehend. No sector has been left behind as everything gets automated. Dental hygiene has also witnessed great technological advancement especially with the coming of the ultrasonic toothbrush.

Despite being around for a couple of decades now, very few people understand exactly how the ultrasonic toothbrush works. It is a fact that it is electronic but how does an ultrasonic toothbrush work? To understand this, it is important for one to know exactly what exactly it is and how it is made.

The ultrasonic toothbrush is tasked with removing plaque from teeth just like the ordinary or manual toothbrush. The main difference is the fact that this brush uses electricity to produce ultrasound. The ultrasound produced is the only difference between this toothbrush and the manual toothbrush.

Shape and Size

The shape and size of this brush are similar to that of an ordinary toothbrush and it is fitted with bristles made from the same material as any other toothbrush. The ultrasound produced is meant to help remove plaque while rendering the bacteria in teeth harmless.

The main and outstanding difference between this toothbrush and the conventional toothbrush is the broad bottom or handle. The handle is broad for this toothbrush as it is where the engine or the mechanical part of the toothbrush is fitted. It is from this point that the vibrations will be generated.

Vibrations

The standard ultrasonic toothbrush operates at a frequency of 1.6 MHz. At this frequency, the toothbrush is able to generate between 96,000,000 and 192,000,000 pulses every one minute. The vibrations are either in and up and down motion or in a circular motion. However, some toothbrushes will combine both motions.

What sets apart the ultrasonic toothbrush from other brushes is the speed of the vibrations. The ultrasonic is the fastest toothbrush with regards to vibrations in the market to date. This means that it is also the most effective as speed is the major determinant of effectiveness.

Effectiveness

According to research findings and commentary from leading experts in the dental field, the ultrasonic toothbrush is the most effective toothbrush in plaque removal. It is credited with the ability to remove plaque from hard to reach places that the conventional toothbrush would not be effective. This effectiveness is a result of the fact that contact is not necessary for the brush to remove plaque.

The ultrasound from this toothbrush is also known to increase the speed of bone and gum healing and stopping gingival healing. This is on top or removal of plaque from any tooth in your dental formula. Ultrasound has also been applied in treating aphthous stomatitis using other medical devices. However, to be effective the frequency has to be between 1 and 3 MHz.

Safety

Just like any other great device, there have been a number of safety concerns ever since the development of the first ultrasonic toothbrush. The main concern is its ability to raise the temperature of surrounding tissues. According to regulations, the power output of these devices should limit its ability to raise the temperature of surrounding tissues by more than 1 C.
