Direct the stream at a 90-degree angle to your gumline. Slightly close lips to avoid splashing but allow water to flow freely from mouth into the sink. For best results, start in the molar area (back teeth) working toward the front teeth. Glide tip along gumline and pause briefly between teeth. Continue process until you have cleaned the inside and outside of both the upper and lower teeth.

Lean low over your sink and place the soft tip against a tooth at a 45-degree angle and gently place the tip under the gum line, into the pocket. Turn the unit on and continue tracing along the gum line until all periodontal pockets are treated.

The special Orthodontic Tip is uniquely designed to simultaneously brush and rinse hard-to-reach areas around braces and other dental work.
Start on the last molar (back tooth). Aim tip at 90 degree angle to the tooth at the gumline. Gently glide tip along gumline, pausing briefly to lightly brush area between teeth and all around orthodontic bracket, before proceeding to the next tooth.
Continue process until you have cleaned the inside and outside of both the upper and lower teeth.

Place the toothbrush tip in mouth with the brush head on the tooth at the gum line. The toothbrush tip can be used with or without toothpaste. Turn the Water Flosser on so water flows through the tip. Using a light pressure (bristles should not bend) massage the brush back and forth with very short strokes – much like you would with a manual toothbrush. Repeat on adjacent teeth. Water will flow through the brush, to help simultaneously clean and rinse the tooth surface.

Direct the jet stream at a 90-degree angle to your gumline. Close lips slightly to avoid splashing but allow water to flow freely from mouth into sink. Start in the molar (back teeth) area working toward the front teeth. Place the tip close to the teeth so that the bristles are gently touching the teeth.
Gently glide tip along gumline, pausing briefly between teeth to gently brush and allow the water to flow between the teeth. Continue until all areas around and between the teeth both inside and outside, top and bottom have been cleaned.

Your Waterpik ^® Water Flosser can be used to deliver mouthwash and antibacterial solutions. Ask your dental professional to recommend the appropriate solution for you. Note: use of some antibacterial solutions could shorten the life of your Waterpik ^® Water Flosser.
After using any special solution in the reservoir, take a moment after every use to rinse the unit. Partially fill the reservoir with warm tap water. Aim the jet tip into your sink. Turn on the unit and let it run until empty. This will help keep the tip from clogging and help your unit to last longer.
Clean the product when necessary by using a soft cloth and mild non-abrasive cleanser.
CARE OF YOUR WATERPIK ^® WATER FLOSSER
Before cleaning, unplug from the electrical outlet.
Before exposing the Water Flosser to freezing temperatures, remove the reservoir and run the unit until completely empty.
