Lean over the sink and place the injector head into the mouth. Align the
nozzle to your teeth. Turn on the pushing switch on the handle to adjust
the water pressure to the desired value. Control the direction of water flow
by turning the knob on the top of the handle.
Using Oral Irrigator
Adjust the water jet flow to 90
degree to the gum line. Close your
lips to prevent the water from
flowing sideways while allowing the
water in your mouth to flow freely
into the sink. For best effect, start
cleaning from the molar teeth (back
teeth) towards the front teeth. Slide
the injector head along the gum line
with short pauses between teeth. DO
NOT stop until the areas around the
gums and among the teeth are
cleaned.

at any time and put the handle back on the body to temporarily stop the
water flow.
Pause control

Using Instruction for Nozzles
High-pressure nozzle
Rinses deep into the mouth thoroughly
to clean the parts hard to be cleaned
with toothbrush. More effective than
floss and making the gums healthier.
Periodontal pocket brush
Tongue Cleaner
The periodontal pocket brush can inject
water or antibacterial fluid into specific
parts below the gum line. When using the
periodontal pocket brush, please lean
over the wash basin, place the soft brush
head against the teeth at an angle of 45
degrees, and gently place the brush head
into the teeth socket below the gum line.
Turn on the device and minimize the
pressure, gently place the brush on the
crevice between teeth, and then clean it
along the direction of the gum line.
Continue to move along the gum line
until the flushing is completed.
Lean over the wash basin. Place the
tongue cleaner on the tongue and start the
oral irrigator: use the lowest pressure first
and then increase the pressure based on
the degree of comfort. Gently place the
tongue cleaner in the middle of the back
part of the tongue and gently pull it to the
front against the tongue.
Orthodontic nozzle
The special orthodontic nozzle is designed to wipe and rinse the areas
hard for braces and other dental appliances to reach. When using the
orthodontic nozzle, lean over the wash basin to wash your teeth with the
nozzle, and water flow will take the debris away.
Dental plaque nozzle
Align the water with the gums at an angle of 90 degrees and slightly
close your lips to prevent water from splashing while allowing the water
to flow out from the corners of the mouth to the wash basin. Start
flushing from the molar teeth (back teeth) and gradually to the front
teeth. The nozzle shall be close enough to the teeth so that the bristles
can gently touch the teeth. Gently move the nozzle along the gums with
a short pause between two teeth to allow the water to pass between the
teeth. Repeat the same procedure on each side of the teeth until all the
part between the teeth as well as the front, back, top and bottom of the
teeth are cleaned.
