A toothbrush cannot reach between the teeth, and that is exactly where plaque most often stays. An interdental brush solves it – if it is the right size and used gently. Here is how.
Key message: A correctly sized interdental brush cleans the places a regular brush cannot reach – the key is size and gentle insertion.

Frequently asked questions
What size should I buy?
There are several sizes and you often need two or three different ones. It is best to have them recommended by a hygienist who measures the individual spaces.
It bleeds – should I stop?
Bleeding at the start is usually a sign of inflammation, not damage. With the right size and gentle technique it usually subsides within two weeks.
Is an interdental brush enough instead of floss?
Where the brush fits, it is usually more effective than floss. For very tight contacts, use floss.
