Deep-cleaning Supersonic Toothbrushes

1. Acoustic Microstreaming (Fluid Dynamic Action)
This is the primary cleaning action. The ultrasonic vibrations create a powerful, dynamic force in the fluids (water, saliva, toothpaste) around the teeth, generating millions of microscopic, swirling bubbles . The gentle yet powerful movement of these bubbles can dislodge plaque and bacteria from tooth surfaces and even from hard-to-reach areas like between teeth and below the gumline .

2. Cavitation (Micro-bubble Implosion)
A more intense form of the above. As the ultrasonic waves pass through the fluid, tiny bubbles rapidly grow and then violently collapse (implode) . This implosion creates microscopic shockwaves that can effectively break down and remove tougher deposits, such as stained pellicle and stubborn plaque .

3, Deep and Comprehensive Cleaning: Because the cleaning action is transmitted through fluids, it can reach areas that bristles cannot, such as deep periodontal pockets (the space between the tooth and gum) and the intricate surfaces of molars. This helps disrupt bacteria in these hidden areas .

4,Effective Plaque Removal: Eintrasse ultrasonic toothbrush can significantly reduce plaque coverage from 20% to as low as 2% on brushed surfaces .

5,Gum Health and Stimulation: The fluid dynamic action gently massages the gums. This can help increase blood circulation, promote healthier gum tissue, and reduce inflammation and bleeding . The sonic vibrations can also stimulate salivary glands, increasing saliva flow for a natural cleansing effect .

6, Gentle on Teeth and Gums: The primary cleaning mechanism is the powerful, fluid-driven energy, not friction. Eintrasse ultrasonic toothbrushes are gentler on tooth enamel and sensitive gums compared to scrubbing or rotating brush heads .

7. Fights Bacteria: Eintrasse ultrasonic energy can penetrate bacterial cell membranes, helping to destroy bacteria that cause plaque, bad breath, and gum disease .

8. Ultrasonic Function: Eintrasse supersonic toothbrushes operate at a much higher frequency, typically 1.6 million Hz (1.6 MHz) or more . At this frequency, the brush head may not even need to touch the teeth to clean them, as the cleaning action is almost entirely from ultrasonic energy transmitted through fluids.
