Here are the precautions for using interdental brushes.

There are points to keep in mind when using interdental brushes.

The spaces between teeth are narrow, but conversely, using a large interdental brush does not work well. Your gums may get injured and bleed. You must be careful about this.

And conversely, if you brush with a size smaller than your teeth The spaces between the teeth will not be cleaned evenly.

Therefore, in such cases, the effectiveness of using an interdental brush may be reduced.

Therefore, it is essential to use one that fits your tooth size.
