Oral-B Smart 4 4900 D601.525

A set of two electric toothbrushes with a reciprocating rotational movement of the nozzle (3D cleaning) and battery power. These models are positioned as affordable mid-range products with a basic set of features. They differ in the presence of two types of head movement at once. Thus, an electric drive generates reciprocating (150 Hz) and pulsating (reciprocating) movements with a frequency of 660 Hz.

The complete Oral-B Cross Action heads have bristles located at an angle of 16° to the plane of the base. This solution allows the bristles to penetrate much deeper than conventional (vertically oriented) and remove plaque that is not removed by conventional manual or low-cost electric brushes. The small round head of the Braun Oral-B Smart 4 4900 D601.525 toothbrush is able to cover and thoroughly clean individual teeth, hard-to-reach areas of the mouth and the gum line.

Green-coloured, flexible Flexi Soft bristles make brushing your teeth as soft and gentle as possible. They also provide deeper penetration of the blue tufts of Interdental Tips, which are designed to effectively clean the gaps between the teeth. Toothbrushes are equipped with a two-minute timer, and the capacity of the Ni-MH battery is enough for 28 minutes of active battery life.
