What is a water flosser used for?
A water flosser, also called an oral irrigator, is used to remove plaque, flush food particles, and massage gums. Unlike string floss, it uses a steady stream of pulsating water to clean between teeth and below the gumline—areas often missed during daily brushing.
- Effective for cleaning around braces, implants, and bridges.
- Helps reduce bleeding gums and gingivitis.
- Removes bacteria from hard-to-reach areas.
- Gentle yet powerful cleaning for sensitive gums.
Step-by-Step Oral Irrigator Instructions
Follow these oral irrigator instructions to make sure you’re using your water flosser the right way:
- Fill the reservoir with lukewarm water for comfort.
- Insert the tip firmly into the handle.
- Choose pressure: start low if you’re a beginner.
- Lean over sink to avoid splashing.
- Close lips slightly to control the flow while letting water drain out.
- Glide along gumline pausing between each tooth.
- Finish in 1–2 minutes and rinse your mouth.

FAQ: How to use a water flosser
Do you brush or floss first?
Most dentists recommend flossing with a water flosser before brushing to loosen debris and allow fluoride toothpaste to work more effectively.
Can a water flosser replace flossing?
Yes and no. A water flosser can replace traditional floss for many people, especially those with braces or implants, but combining both offers the most thorough clean.
How often should you use it?
Use your water flosser at least once daily for best results. Twice a day is ideal if you’re prone to gum disease or wear orthodontic appliances.
Is it safe for sensitive gums?
Yes. Start with the lowest pressure setting and gradually increase as your gums adjust. Many find water flossing gentler than string floss.
