Use The GUM Sonic Daily electric toothbrush (model 4100MBK2, which is part of the 4100 series) is designed for daily hygiene procedures. It provides high-quality cleaning of the tooth crown and areas below the gum line thanks to bristles with ultra-thin conical ends. Sonic vibration up to 12000 Hz contributes to more effective cleaning compared to a regular toothbrush. The brush can be used for: - cleaning implants - daily tooth cleaning - plaque removal - tooth crown whitening - tooth surface polishing - How to take Information on ''How to take'' is not applicable to an electric toothbrush, as it is not a medication or supplement. The toothbrush is used for mechanical tooth cleaning. - Contraindications Specific contraindications for the GUM Sonic electric toothbrush (4100) are not explicitly stated. However, general recommendations for electric toothbrushes include caution for highly sensitive teeth, as overly intense action may be undesirable. In such cases, it is recommended to use a delicate cleaning mode, if available, or consult a dentist.
