Change the way you use and move the appliance depending on the purpose and the area you want to clean.

Interdental cleaning

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

Periodontal pocket cleaning

Direct the water jet onto the space between the teeth and gums.
Slowly shift the water jet along the gums.
Clean the front and rear sides of the teeth as well as behind the molars.

About tooth tartar
It is hard to remove tooth tartar or dental calculus attached to the tooth surface just by a water jet, so a toothbrush is required to brush the teeth.
It is recommended to clean inside your mouth with the water jet after brushing your teeth.

About bleeding gums
Initially bleeding may occur even with healthy gums. This is caused because the gums are not used to such stimulation. The bleeding will normally stop within 1 or 2 weeks of use. There may be a problem with the gums (periodontal disease, etc.) if the bleeding continues for over 2 weeks. In such cases, stop using the appliance and consult a dentist.
