Use an interdental brush to clean the gaps between teeth
Just like dental floss, interdental brushes are tools used to remove food debris stuck between teeth or plaque in the spaces between teeth that cannot be removed by brushing alone.
If there are areas between your teeth where the gums have receded and are not filled, it is recommended to use an interdental brush that fits that size.
In particular, if there are areas where food particles are stuck, it is said that you must remove them with an interdental brush to maintain healthy gums.
The usage is as follows.
First, when using an interdental brush, ensure the curved bristles are level with the teeth. Then, gently slide it between the teeth to avoid injuring the gums or teeth, and move it back and forth carefully.
When using an interdental brush, you must insert it not only from the outer surface of the tooth (cheek side) but also from the inner side (tongue side, palate side).
In addition, when using an interdental brush, you must use only water, not toothpaste.
However, there are also precautions.
If the spaces between your teeth are too narrow for an interdental brush to fit, forcing it in can cause adverse effects such as injuring your gums, so it is recommended to use dental floss instead for those areas.
It is most advisable to find the size that fits you best.
