Why Ultrasound

The Emmi-dent Ultrosonic Toothbrush has been likened to a "Symphony at its Best".

It offers daily superior dental hygiene with an added prophylaxis effect for everybody (utilising up to 96 million oscillations per minute)."

So far, dentists and scientist have recommended having one's teeth professionally cleaned at least once per year. These cleanings are typically done in dental surgeries, by dental hygienists or assistants.

The coverage of costs by statutory medical insurances differs between insurance companies in each country. We recommend contacting your medical insurance company regarding the coverage of costs upfront. However, would it not be even more valuable to have the opportunity to have a regular and thorough teeth cleaning and oral hygiene programme to a professional standart, that could take place at home? An effective method of daily prophylaxis and dental therapy?. A comparison between traditional teeth cleaning methods and cleaning with Emmi-dent's Ultrasonic Toothbrush is as follows:

 Traditional teeth cleaning


Teeth cleaning with Emmi-dent Ultrasound

Manual, electric, or sonic brushes


100% Ultrasonic brush

Cleaning through mechanical friction by means of abrasive substances in the toothpaste (RDA value 70–130, which poses great risk of injuring dental enamel and gums)

Motionless cleaning (no brushing, less irritation to gums) No abrasive particles (RDA value = 0) therefore, no damage to the enamel or gums.

30-35,000 mechanical rotations per minute
(unpleasant friction)

Up to 96 million air oscillations per minute (pleasant "micro-massage")

Cleans only where bristles are able to, using abrasive action.


Cleans via implosion of micro-bubbles (in the toothpaste), even within the smallest cavities, fissures and gingival pockets, penetrating 12mm into tissue and areas where bristles cannot reach. Removes discoloration caused by wine, nicotine, food...

Typically requires additional means such as dental floss, interdental brushes, mouthwashes, etc.


Ultraclean = No additional cleaning required.

Prophylaxis for areas reached by bristles (e.g. surface cleaning only, no deep tissue cleansing); regular visits for prophylaxis treatments with dentist or hygienist required(expensive).


Prophylaxis for complete dentition, including gingival pockets; breaks down bacteria and gives deep and lasting protection e.g. removes bacteria around dental implants, crowns, build-ups, orthodontic braces etc.

No therapeutic effect.


Therapeutic effect within a few days, even in advanced or acute cases (e.g. inflammation, mouth ulcers...).

Don’t be confused by large marketing budgets: A Sonic Brush is NOT Ultrasonic!

A Sonic Brush is cleaning through mechanical friction by means of abrasive substances in the toothpaste.

Emmi-dent generates ultrasound with a patented ultrasonic microchip that is embedded inside the toothbrush head. This chip creates up to 96 million ultrasonic vibrations (air oscillations) per minute and transmits them via the bristles and micro-bubble toothpaste onto the teeth giving you a superior cleaning. The ultrasonic vibrations are able to penetrate teeth and gums destroying bacteria and germs where bristles can’t reach. This is essential in reducing and protecting against periodontal (gum) disease. Specially formulated micro-bubbles are up to 1000x smaller and are able to reach between the teeth, into the smallest crevices, supporting and enhancing the cleaning effect of ultrasound. MNano-bubble cleaning removes plaque, tartar, food remnants and impurities.
