Звуковые электрические зубные щетки
Sonic
— brushing technology that provides vibrations of bristles with a small amplitude at a high frequency — up to 40K vibrations per minute; this speed corresponds to the frequencies of audible sound.This operating method is regarded as more advanced than reciprocating and reciprocating sweeping technologies. Sonic brushes, due to their high vibration speed, generate a fine and uniform foam from toothpaste, saliva, and air during cleaning. This foam easily reaches even the most challenging spots and is effective in removing plaque, including from interdental spaces. While ultrasonic technology is considered even more advanced (as discussed in the relevant section), sonic brushes are relatively more affordable and excel at cleaning braces and similar dental structures.
