Portable Oral Irrigator
Thank you for choosing a Nicefeel oral irrigator!
You’re on your way to a more hygienic life!
Thank you for purchasing a portable oral irrigator from Nicefeel, a
pioneering and innovative brand with the world's most advanced
high-pressure water pulse technology.
Conventional toothbrushes cannot easily remove food debris hidden in
the oral cavity, while most dental floss can only reach a limited area
under the gums. In contrast, Nicefeel oral irrigators can quickly and
efficiently remove food debris from deep in the gums and between the
teeth to ensure perfect hygiene.

that water can flow freely from your mouth to the sink.
Techniques
Before using the device, lean slightly over the sink, extend the nozzle
into your mouth and aim it at the teeth, gums, or between the teeth.
Rotate the nozzle to adjust the direction of the water outflow so that it
is perpendicular to the part of your mouth you wish to clean. Ensure that
your mouth is open enough so that any water flows right out.
