Electric toothbrushes with reciprocating brushing

Reciprocating brushing

— historically — the first of the technologies used in toothbrushes with oval heads. The bristles in models with this principle of operation oscillate left and right, like broomsticks. Classic reciprocating brushes are simple in design, but not very effective. As a result, there are few such models nowadays, mainly low-cost devices, and most toothbrushes with oval heads use more advanced sonic or ultrasonic technology.
