High-frequency electric toothbrushes

High oscillation frequency

— sonic toothbrushes, which have a high operating frequency of 50,000 vibrations per minute or more, provide fast and effective cleaning. However, this high speed is not always desirable: for instance, with increased tooth enamel sensitivity, the intense action may cause discomfort. Therefore, it is best to purchase a toothbrush with this feature after consulting a dentist — or you can choose a model with a sensitive teeth mode (see "Functions (brushing modes)").
