An improved toothbrush characterized in that the body of its head adopts a recessed shape integrated by longitudinal bars in which the bristle bundles are mounted, these bars being connected at intervals by narrow transverse stools and at least one the faces of lower height than the bars, resulting in the formation of elongated and rectangular holes that facilitate the passage of the toothpaste through the body of the head of the brush, preventing it from accumulating between the base of the bristles.
