Best ultrasonic toothbrush: New Technology for Clean Healthy Teeth

Ultrasonic toothbrushs

Are you new to ultrasonic toothbrushes? Yes? You have landed the right place.

What exactly is an ultrasonic toothbrush?

It is an electric toothbrush all right – only with a typical frequency level. This altered frequency places ultrasonic electric toothbrushes in a different category altogether. An advanced ultrasonic motor can give a frequency close to 1.6MHz to the electric toothbrush.

If you do the math, we have between 96M and 192M strokes in a minute. Quite naturally, these toothbrushes are beyond the range of human audibility.

Sonex Corporation is credited for designing the first ultrasonic toothbrush in 1992.  The same year Food & Drug Administration approved it healthy for daily use.

As it is, toothbrushes use the most updated of technologies. And the innovation continues to add improvement to toothbrush designs.

A small fact: most manufacturers found ultrasonic technology too difficult to handle. This reflects poorly on their product lines.

Only some selected companies succeed in maintaining technological standards and manufacturing quality that helps to make ultrasonic toothbrushes. Smilex is one great exponent of ultrasonic toothbrushes.

The thin response to ultrasonic toothbrush manufacturing means we have limited options to choose from. Here is a collection of all that is noteworthy among ultrasonic toothbrushes.

A brief history of the ultrasonic toothbrush

The Ultima was the first toothbrush to employ ultrasonic technology and it was patented in the year 1992 in the USA.

It received approval for regular use at home by the FDA (Food and Drug Association) the same year and as per regulations, any electric toothbrush must operate at 1.6 MHz frequency or 192,000,000 strokes each minute in order to classified as an ultrasonic toothbrush.

Nowadays, there are some toothbrushes that only provide ultrasonic motion while others offer extra sonic vibrations ranging between 9,000 to 4,000 strokes per minute.

Sonic vs. ultrasonic toothbrush! What is the difference between these two?

When you use advanced sonic toothbrushes, the motor of the device produces a humming sound that can clearly be heard by the human ear. On the other hand, ultrasonic toothbrushes are powerful enough not to rely on physical motions for the purpose of cleaning the teeth.

A sonic electric toothbrush is capable of producing almost 12 - 24,000 oscillations in a single minute while an ultrasonic toothbrush offers 2,400,000 movements each minute. Sonic toothbrushes have a high amplitude that lead to bigger brush strokes. However, in order to gain approval from the FDA in the USA, an ultrasonic toothbrush needs to produce 192,000,000 movements in a single minute.

The bristles of a sonic toothbrush are responsible for sweeping away bacteria and particles while sonic toothbrushes can clean bacterial chain remnants as well as food particles.

Effectiveness of ultrasonic toothbrush

Ultrasonic toothbrushes tend to provide you with better cleaning capabilities and they can work on areas that are usually difficult to reach for the bristles of normal toothbrushes.

The effectiveness of an ultrasonic toothbrush can actually be judged upon your daily dental practices but it is true that an ultrasonic toothbrush does clean sections of the mouth that a normal brush cannot due to the fact that the extreme vibration results in a great deal of motion and energy, powering mouth fluids in parts below the gum line and between teeth.

Safety of ultrasound toothbrush

Ultrasound toothbrushes are usually safe to use due to the fact that outstanding quality electric toothbrushes come with very soft bristles that cannot damage the interior of the mouth.

However, for the sake of safety, you should maintain care when brushing, especially above and below the gumline since these portions are very sensitive.Moreover, you should not make any movements with the brush but just hold it in your mouth and let the product do all the work.

It’s time to decide....

Plenty of companies are involved in the design and manufacture of ultrasonic toothbrushes and they aim to create the best product possible that ensures clean teeth and healthy gums with the least amount of effort.

The more developments take place in the world of technology, the closer they get to their goal and the number of ultrasonic toothbrushes has increased in the market.However, at present the best product in this category is definitely the Straight recommendation:  AU-300E Original Ultrasonic Electric Toothbrush from brand Smilex. 

Bottom line

You should be careful to select the best ultrasonic toothbrush in the market depending upon your needs so that you get good value for money.
