Do You Really Need to Floss Every Day?

Brushing cleans the surfaces of your teeth, but it misses the gaps between them — and that's where flossing comes in. Yes, daily flossing is worth it: it removes plaque and food from between the teeth and under the gumline, where a brush can't reach. Here's why, and how to do it well.

Why flossing matters

• Prevents gum disease. Flossing removes the plaque that causes gingivitis, the early stage of gum disease. See gum disease: facts you should know.
• Reduces cavities. Food and plaque trapped between teeth cause decay; flossing clears those hard-to-reach spots.
• Freshens breath. Removing trapped food and bacteria helps keep breath fresh.
• Supports overall health. Gum health is linked to your general health — see how oral health affects your body.

How often, and how

Floss once a day. If you're new to it, your gums may bleed a little at first; this usually settles within a week or two as they get healthier. If bleeding persists, get it checked.

• Be gentle. Don't snap the floss — guide it gently between the teeth.
• Use enough. About 45cm, so you have a clean section for each tooth.
• Curve around each tooth. Form a C-shape and clean just below the gumline.

If you don't like floss

Water flossers and interdental brushes are effective alternatives — a water flosser uses a stream of water, while interdental brushes fit into the gaps. Either is more effective than skipping between-teeth cleaning altogether.
