What variety of automatic toothbrushes are available?

The correct response highlights that there are automatic toothbrushes designed with various modes of movement, which can significantly enhance the efficacy of oral hygiene practices. These toothbrushes typically include features such as pulsating, circular, and oscillating actions. Each mode can cater to different cleaning needs and preferences, adapting to an individual's oral health requirements.

For instance, some toothbrushes may utilize oscillating-rotating movements, while others might have sonic technology that produces high-frequency vibrations to help dislodge plaque effectively. The versatility of these modes allows users to select the setting that best fits their oral care routine, providing a thorough and tailored approach to brushing.

Additionally, the other options miss the mark by either limiting the types of automatic toothbrushes available or oversimplifying their features, thereby not accurately reflecting the advancements in toothbrush technology.
