More preferably, the linear reciprocating mode for providing the linear reciprocating force and the mixing mode for the driving means for providing the rotational force and the linear reciprocating force at the same time are more preferable.
- a tongue cleaner of a silicon material detachably coupled to the drive means.
- the bristles due to the radially planted structure on the outer circumferential surface of the cylindrical toothbrush rod rotating the bristles can not only remove the food debris stuck in the tooth surface and interdental gap without damaging the gums, but also between the bristles
- the planted silicon hair has the effect of removing the plaque on the tooth surface more reliably.
- the bristles of silicon hair planted between the bristles support the bristles to prevent deformation of the bristles, as well as a space for accommodating the toothpaste between the silicone bristles to prevent the toothpaste from easily flowing.
- the tongue cleaner of the removable silicon material is further provided to facilitate the tongue cleaning.
