Advantages

The sonic cleaning technology produces high-frequency bristle movement to assist in plaque removal along tooth surfaces and gum lines. A built-in Li‑Ion battery provides rechargeable power without the need for disposable cells, and the included two brush heads allow for regular replacement or shared use between users in a household. The integrated timer helps achieve dentist-recommended brushing duration while the compact size and 0.4 kg weight make the unit easy to handle and pack for travel.

How to use

Apply toothpaste to the brush head, place the bristles against the teeth at a slight angle toward the gum line, and switch the device on. Move the brush gently across tooth surfaces, allowing the sonic action to work without applying excessive pressure. Follow the integrated timer to ensure an adequate brushing duration, then rinse the brush head and handle under running water if the design permits. Replace brush heads periodically or when bristles show wear.

Usage recommendations

For effective daily oral care, use the Concept Solution ZK4040 twice a day with fluoride toothpaste and replace brush heads every three months or sooner if bristles are frayed. Keep the handle and charging contacts dry when not charging, and follow any specific charging and maintenance instructions provided by the manufacturer to preserve battery life.
