How to Floss Properly

Learn the correct flossing technique for healthier gums.

Why Flossing Matters

Flossing removes plaque and food particles from between teeth and below the gum line—areas your toothbrush can't reach. Skipping flossing allows plaque to build up, leading to cavities, gum disease, and bad breath.

Proper Flossing Technique

Follow these steps:

  • Use about 18 inches of floss, winding most around middle fingers
  • Hold floss tightly between thumbs and forefingers
  • Guide floss gently between teeth using a rubbing motion
  • Curve floss into a C-shape against each tooth
  • Slide floss gently up and down against tooth surface
  • Go below the gum line
  • Use clean section of floss for each tooth

Flossing Alternatives

If traditional floss is difficult:

  • Floss picks or holders
  • Water flossers (Waterpik)
  • Interdental brushes
  • Soft picks
  • Air flossers

When to Floss

Floss at least once daily, preferably before brushing at night. This allows fluoride from toothpaste to reach between teeth. The most important thing is to floss consistently—any time is better than not at all.

Frequently Asked Questions

Should I floss before or after brushing?

The ADA says either is fine, but many dentists recommend flossing first. This removes debris between teeth so fluoride from toothpaste can reach those surfaces. The most important thing is that you floss daily.

Why do my gums bleed when I floss?

Bleeding usually indicates gum inflammation (gingivitis) from plaque buildup. With regular flossing, bleeding should stop within 1-2 weeks as gums become healthier. If bleeding persists, see your dentist.

Are water flossers as effective as string floss?

Studies show water flossers can be as effective as traditional floss, especially for people with braces, implants, or dexterity issues. The ADA has accepted some water flossers. The best option is whichever you'll use consistently.
