Welcome to a New Level of At-Home Dental Care
Water Jet enhances oral hygiene and significantly contributes to
healthy gums when used as part of a responsible oral health management program.
It is particularly effective at cleaning around orthodontic appliances, fixed and
removable bridge work, implants and splints, and it provides valuable gum massage
with every use.
Remember: Oral irrigation is a supplement to, not a substitute for, your oral hygiene
routine. Ask your dental health care provider to advise you on how
the Water Jet can most effectively meet your specific oral needs.
Instructions For Use
Remove the water reservoir (2) and fill with lukewarm water. Reinstall the reservoir
firmly onto the unit (1). Prior to initial use, the unit should be rinsed by letting a
full reservoir of water pass through it. If the unit is to be used with a mouthwash
solution, it should be rinsed with clean water after each use to remove any traces of
mouthwash. If the unit has not been used for a long period of time, for reasons of
hygiene it is advisable to follow the directions for initial use, letting a full reservoir of
water pass through. To remove trapped air upon initial operation, turn the rotary flow
control (7) all the way to the right and then to the left, three times.
Prior to filling the water reservoir, make sure water tip is firmly placed on and in the
stand. The Water Jet is supplied with 5 attachments. Remove the tip support (3) and
install selected tip:
Standard Tip (2pcs): removes trapped particles from between teeth.
Subgingival Tip (1pc): uses a soft rubber tip to massage the gums and safely deliver
solution into the gingival pockets below the gumline.
Brush Head Tip (1pc): loosens debris and larger food particles before flushing them
away – ideal for all dental work, including fixed and removable appliances.
Tongue Cleaner (1pc): place the tongue cleaner at farthest end of tongue and move
forward. Repeat to cover entire tongue. After switching on (6) the unit, the rotary
flow control (7) can be used to regulate the water pressure. You should begin with
the lowest setting so that your gums can become accustomed to the water jet.
Hold the fingertip on/off control (water-stop button) (4) down and, after switching on
the unit, place the tip in your mouth and lean over the sink. When you release the
water-stop button, the cleaning and massage process is begun. The direction of the
water jet in your mouth can be controlled by twisting the tip to the desired position on
the handle. Keep your mouth slightly open and hold your elbow at mouth level so that
the water can run back into the sink. Direct the water jet toward your teeth, especially
between your teeth, in order to rinse away stubborn remaining food.
This also massages your gums. Do not point the water jet directly toward your gums;
point between your teeth to prevent damage to delicate gum areas.
