Flossing 101: Why It Matters and How to Do It Properly
Half of every tooth surface never sees a brush. Here's why daily flossing matters more than you think — and how to make it painless.
Flossing is the step people most love to skip — and the one dentists most wish you wouldn't. Your toothbrush simply can't reach the surfaces between your teeth, which is exactly where decay and gum disease like to begin.
Why brushing isn't enough
Brushing cleans only about 60% of each tooth's surface. The tight contact points between teeth trap plaque and food particles, and a brush head can't fit there. Floss is the tool designed for precisely that gap.
How to floss properly
- Use about 18 inches of floss, wound around your middle fingers.
- Guide it gently between the teeth — never snap it down into the gum.
- Curve it into a C-shape against the side of each tooth.
- Move it up and down, slightly below the gum line, using a fresh section for each gap.
Floss, picks, or a water flosser?
- Traditional floss — the gold standard, and inexpensive.
- Floss picks — convenient, and far better than nothing.
- Water flossers — excellent for braces, implants, or limited dexterity.
The best option is simply the one you'll use every day.
Bleeding when you first start flossing usually signals inflammation, not damage. Keep going gently and it typically settles within a week or two.
When to floss
Once a day is enough, and the evening is ideal. Floss before you brush so fluoride can reach the gaps you've just cleaned.
The bottom line
Daily flossing prevents cavities between teeth and is one of the strongest defenses against gum disease. Pick a tool you actually like, and make it automatic.
