The Sonic Generation 12 Winner® UFSBD Bacterio (SG12) has four different cleaning modes, allowing you to customise your routine according to your requirements.
The Sensitive mode is for gentle cleaning, but don’t be fooled! Though the feel is soft, the clean is thorough. In fact, the Sensitive mode operates at the highest frequency, which equates to 42,000 strokes per minute.
You may be wondering how the highest frequency offers the gentlest clean. To understand this, we’re going to take you back to a physics lesson you probably had in school. Remember learning about the frequency and amplitude of sound waves? No, us neither! Don’t worry – we brushed up on it and we’ll explain how these two measurements have an impact on the SG12.
The Whitening mode naturally whitens teeth by ridding their surfaces of pesky stains. This mode has the lowest frequency and highest amplitude - a ratio that is optimal for enhanced mechanical cleaning and removal of surface stains.
The Active Deep mode is for thorough plaque removal. It has a lower frequency and a higher amplitude, so the sweeping motions are greater as is the disturbance of plaque. This mode is ideal for when you want a deep clean.
In the context of a sonic toothbrush, the frequency is the speed at which the bristles move (i.e. the number of side-to-side movements they make) and the amplitude is the range of this motion (i.e. the width of the side-to-side movements of the bristles). While the Sensitive mode has the highest frequency, it also has the lowest amplitude. This means that the bristles are moving back and forth very fast, but their sweeping motion is narrow.
As a result, the teeth are efficiently cleaned but the restricted movement of the bristles provides you with more control over where the bristles come into contact with the teeth and gums.
This allows you to avoid sensitive areas and limit the occurrence of any irritation.
