Straight interdental brushes, 0.4 mm
MEDIBLANC Interdental Brush 0.4 mm (ISO 0) is the smallest size of the range, made for narrow gaps. The straight I-shaped brushes remove plaque and food debris from the spaces between the teeth, where a regular toothbrush cannot reach. The pack contains six pink, colour-coded brushes.

- Handle for a comfortable grip

How to Choose the Size
The brush should fill the gap without noticeable resistance. If you are not sure, start with the Mix Pack or ask your dentist or hygienist.
Clean the spaces between your teeth at least once a day, ideally in the evening before brushing.
- Gently insert the brush between two teeth at the gum line, then straighten it to a horizontal position.
- Move it gently back and forth without force; small circular movements clean more thoroughly.
- Pull the brush back slowly and repeat for every gap.
- Rinse the brush after use and replace it when the bristles are worn.
Never push the brush into a gap by force. The gums may bleed slightly during the first days of use; if bleeding continues, ask your dentist.
