• Mechanical cleaning. This is the main action. Cleaning is accomplished thanks to the mechanical action performed by the filaments, which vibrate at a high frequency on the surface of the teeth, helping to remove dental plaque, or biofilm.
  
• Acoustic and hydrodynamic vibration. Due to the high speed at which the filaments vibrate, acoustic waves are sent out. These waves and the energy associated are transmitted through the saliva throughout the oral cavity, exerting pressure fields that disrupt the biofilm and prevent its adhesion, even beyond the reach of the filaments themselves. This action occurs even without direct contact between the brush filaments and the teeth, at a distance of up to three millimetres. In addition, because of the vibratory movement, certain amounts of air enter into the saliva, which causes the formation of tiny bubbles that are pushed towards the areas where the plaque builds up. These bubbles are rich in oxygen and when they reach the subgingival areas, which have little oxygen, they expose the anaerobic colonies to an increased oxygen concentration (an unfavourable medium for their growth). Fluid dynamics can alter dental plaque in hard-to-reach areas such as between the teeth or below the gum line⁽²⁾.
  

Thus, the basic advantage of sonic brushing compared to other technologies is that it adds fluid dynamics to the action of conventional mechanical cleaning (friction).

This action helps to disrupt bacterial colonies and, in turn, inhibits their growth and development. By accessing hard-to-reach areas, it also helps to dilute and eliminate toxins produced by bacteria residing therein. Both actions help minimise the negative effects of oral biofilm.
