What do the colours mean on interdental brushes?

The colours on interdental brushes indicate the size of the brush. Different colours correspond to different diameters of the bristles and the wire core, allowing users to easily identify and select the appropriate size for their interdental spaces.

Here’s a guide to the TePe colours and their corresponding sizes:

1. Pink: Very small, 0.4 mm
2. Orange: Small, 0.45 mm
3. Red: Small-medium, 0.5 mm
4. Blue: Medium, 0.6 mm
5. Yellow: Medium-large, typically 0.7 mm
6. Green: Large, 0.8 mm
7. Purple: Larger, 1.1 mm
8. Grey: Extra large, 1.3 mm
9. Black: Extra large, typically 1.5 mm

It's important to choose the correct size to effectively clean between teeth without causing damage to the gums.
