— round brush heads are predominantly used in toothbrushes employing reciprocating technology. Unlike oval-shaped counterparts, they have a smaller surface area, which may require more time for thorough teeth cleaning. However, they excel in reaching tricky spots like interdental spaces. An important benefit is their gentler cleaning, which is especially valuable for individuals with sensitive teeth. Nevertheless, in toothbrushes equipped with sonic or ultrasonic technology, round heads often lose their edge over oval ones and are less common.
