Why flossing matters

Flossing reaches areas your toothbrush cannot. Around 40 percent of your tooth surfaces sit between your teeth, where plaque builds quickly. Without flossing, plaque hardens into tartar and irritates your gums.

Flossing is one of the simplest ways to keep your mouth healthy.

How to floss properly

Step 1: Take the right amount of floss

Use around 40 centimetres of floss. Wrap most of it around your middle fingers, leaving a short section to work with.

Step 2: Hold the floss correctly

Use your thumbs and index fingers to guide the floss.

Step 3: Slide gently between teeth

Avoid snapping the floss. Glide it slowly between each tooth.

Step 4: Curve the floss

Wrap the floss into a C shape around the side of each tooth.

Step 5: Clean under the gumline

Slide the floss slightly under the gumline to remove plaque.

Step 6: Use a clean section each time

Move to a fresh part of the floss for each tooth.

How often you should floss

Floss once a day.Morning or night does not matter.Consistency is what keeps gums healthy.

Flossing mistakes to avoid

Snapping the floss

This can damage your gums.

Only flossing before dental visits

Plaque builds daily, so flossing should be routine.

Stopping because gums bleed

Bleeding is often a sign of inflammation.Flossing helps reduce it over time.

Using too little floss

Short floss makes cleaning harder.

Floss vs interdental brushes

Tool Best for Benefits
Floss Tight spaces Reaches narrow gaps
Interdental brushes Larger gaps More effective for wider spaces

Should flossing hurt

Flossing should not be painful.Mild tenderness is normal if you are new to flossing.Bleeding usually improves within a week of daily flossing.

Flossing with braces or aligners

Braces

Use floss threaders or orthodontic floss to reach under wires.

Clear aligners

Remove aligners before flossing.Floss normally and clean aligners separately.

Signs you need to floss more often

You may notice:

  • Bleeding gums
  • Bad breath
  • Gum tenderness
  • Food stuck between teeth
  • Yellowing near the gumline

These are early signs of gum inflammation.

How flossing improves long term oral health

Reduces gum disease risk

Flossing removes plaque before it hardens.

Prevents decay between teeth

Toothbrushes cannot reach these areas.

Plaque and trapped food cause odour.

Supports whitening results

Clean gums and teeth look brighter.

Your flossing questions answered

Should I floss before or after brushing

Either is fine. Consistency matters most.

Is flossing better than mouthwash

Yes. Mouthwash cannot remove plaque between teeth.

Can children floss

Yes, with help until they develop good technique.

Do I need to floss if I use interdental brushes

Many people benefit from using both.
