Tips of use

Interdental cleaning

• Direct the water jet onto the space between the teeth.
• Direct from the front and rear sides of the teeth.

With the water jet, the space between the teeth that cannot be reached with a toothbrush is cleaned thoroughly, and the dirt trapped in periodontal pockets is removed completely. In addition, effective care is provided for the gums by comfortable intermittent stimulation.

Illustration showing water jet cleaning between teeth.

Periodontal pocket cleaning

• Aim the water jet at the space between teeth and gums.
• Slowly shift the water jet along the gums.
• Clean the front and back of the teeth and behind the molars as well.
• If you are concerned about sensitive gums, clean with a gentle water jet setting.

Illustration showing water jet cleaning along the gums.

Gums care

• Stimulate the gums with the water jet.
• If you are concerned about sensitive gums, stimulate with a gentle water jet setting.

Since plaque adhering to the surface of teeth cannot be removed only with water jet, brushing is always necessary. It is recommended to clean inside your mouth with the water jet after brushing your teeth.
