Cleaning between your teeth removes plaque and food debris from places a toothbrush cannot reach.

This includes the spaces between teeth and just under the gumline.

Doing this every day helps:

• Prevent tooth decay.
• Protect against gum disease and bleeding.
• Reduce bad breath.

What’s the best way to clean between teeth?

There are two main ways to clean between teeth:

• Interdental brushes
• Floss

Your dental team can help you choose what works best for you. Many people use a mix of both.

Using interdental brushes

Interdental brushes are small brushes designed to fit between teeth.

They are often easier to use than floss, especially if the spaces between teeth are larger.

How to use them:

• Use them once a day.
• Ask your dentist or hygienist to show you the correct brush size for each gap.
• Hold the brush gently between your thumb and forefinger.
• Carefully guide the brush between your teeth.
• Do not force it through.
• If the brush bends or splays, try a smaller size.
• Rinse the brush during use and replace it when worn.

Using dental floss

Floss is useful for tight spaces where brushes may not fit.

How to floss:

• Break off about 45 cm (18 inches) of floss.
• Wind most of it around one finger on one hand and the rest around the same finger on the other hand.
• Hold the floss firmly, leaving a small section to work with.
• Gently guide the floss between your teeth using a slow, rocking motion.
• Do not snap it into the gums.
• When it reaches the gumline, curve it into a C-shape around one tooth.
• Gently slide it up and down the side of the tooth.
• Repeat on the other side of the gap.
• Don’t forget the back of your last tooth.

To avoid missing teeth:

• Start at the top left and move across.
• Then clean the bottom teeth from left to right.

Should I clean between teeth before or after brushing?

Many people find it helpful to:

• Clean between teeth before brushing.

This allows fluoride toothpaste to reach between the teeth more effectively.

Tips to make it easier

• Start slowly and build the habit.
• Mild bleeding is common at first and usually improves with regular cleaning.
• If bleeding continues, speak to your dental team.
• Choose the method you are most likely to use every day.
