Pressure floss
A water flosser uses a pulsed stream to disrupt debris and plaque around teeth, gum margins, braces, and dental work.
The short answer
A water flosser directs a pulsed stream of water along the gumline and between teeth, helping flush debris and disrupt plaque when used with ordinary brushing and any cleaning method your dentist recommends.
How does pressurised water differ from string floss?
The device contains a reservoir, pump, and tip that deliver pressurized pulses rather than a strand of floss. The stream can reach around orthodontic brackets, bridges, implants, and tight gum contours, but it does not replace brushing the tooth surfaces or a professional assessment of periodontal pockets.
How should you use a water flosser safely each day?
Fill the reservoir with lukewarm water, start at a low setting, lean over the sink, and guide the tip along the gumline and between teeth. Use a regular brush as well, clean the device as instructed, and ask whether floss, interdental brushes, or a specific tip is better for your contacts or dental work.
When should bleeding or swelling need dental assessment?
Ask for an examination if gums bleed repeatedly, feel sore, recede, or remain swollen despite daily cleaning. A dentist or hygienist can demonstrate the angle and pressure and check for calculus, cavities, or periodontal pockets.
Which water flosser setting suits your gums and dental work?
Ask which pressure setting and tip fit your gums, implants, braces, bridge, or periodontal pockets, and whether an interdental brush would clean a particular space more effectively.
Frequently asked questions
Is pressure floss the same as string floss?
No. A water flosser uses pulsed water, while string floss mechanically wipes the tooth contact and adjacent surfaces.
Why do my gums bleed with a water flosser?
Inflamed tissue may bleed when cleaned, but forceful pressure or an incorrect angle can also irritate it; adjust gently and arrange an assessment if bleeding persists.
