How to Floss Properly: A Step-by-Step Guide

By New Dental Center, Al Ain, UAE · Teeth Cleaning

Flossing is one of the most recommended and least practised parts of oral hygiene. Many people who do floss use a technique that misses the areas where plaque actually builds up. Done properly, flossing takes only a couple of minutes a day and makes a real difference to gum health, bad breath and decay between the teeth. Here is how to get it right.

Why Flossing Matters

Your toothbrush cleans the outer, inner and biting surfaces of your teeth, but the bristles cannot reach the tight contacts where neighbouring teeth touch. Plaque left in these spaces irritates the gums, causing inflammation and bleeding, and produces acids that cause cavities between the teeth. These cavities are often hard to see until they become large. Cleaning between the teeth once a day disrupts this plaque before it hardens into tartar, protecting both teeth and gums.

Step One: Use Enough Floss

Break off about forty to fifty centimetres of floss. Wind most of it around the middle finger of one hand and a small amount around the middle finger of the other hand. This lets you use a fresh section for each gap as you go. Hold a short length, about two to three centimetres, tightly between your thumbs and index fingers so you have good control.

Step Two: Ease It Between the Teeth

Guide the floss gently between two teeth using a slow back-and-forth sawing motion. Never snap the floss down into the gum, as this can cut or bruise the tissue. If a contact is very tight, angle the floss slightly and keep the gentle sawing motion until it slides through.

Step Three: Form a C-Shape

This is the step most people miss. Once the floss is between the teeth, curve it into a C-shape around one tooth and slide it gently down just below the gumline until you feel resistance. Then move it up and down against the side of the tooth several times. Next, curve it around the neighbouring tooth and repeat. Each gap therefore has two surfaces to clean.

Step Four: Work Around the Whole Mouth

Move to a clean section of floss and repeat for every gap, including the back surface of the last tooth in each row. Follow the same order every day, for example starting at the upper right and finishing at the lower right, so you do not skip any areas. The whole process usually takes two to three minutes once it becomes routine.

Dealing with Bleeding Gums

If your gums bleed when you start flossing, do not stop. Bleeding is usually a sign of inflammation caused by plaque that has been left between the teeth. With gentle daily flossing, bleeding usually reduces within one to two weeks as the gums heal. If bleeding persists beyond two weeks, or your gums are painful or swollen, book a check-up to rule out gum disease.

Choosing the Right Floss or Alternative

Waxed floss slides more easily through tight contacts, while tape is wider and comfortable for larger spaces. Floss picks can help people who find wrapping floss difficult, though they are less flexible for forming a C-shape. Interdental brushes and water flossers are excellent alternatives, especially for braces, bridges, implants or larger gaps. The best tool is the one you will use every day, so ask your hygienist to recommend options that suit your teeth.
