The interdental sides of our teeth, those where the teeth contact each other, cannot be cleaned with the usual toothbrush, so dental plaque should be removed by inserting dental floss, dental tape or interdental brushes between the teeth at least once a day.
When there is enough space between teeth, an interdental brush should be inserted at the base of the space and repetitive back-and-forth movements should be made. This habit is not only intended to remove food debris that remains between the teeth, but also to clean the film of bacteria that adheres firmly to the dental walls, which is the cause of cavities and gum diseases such as periodontitis.
Choosing the right interdental brush
For interdental hygiene to be effective, the interdental brush should not fit loosely in the gap between the teeth, nor should it be forced in by the use of a brush that is too large, because it could injure the gums. This is why there are several brush diameters. From a practical point of view, the ideal would be to use 1 or 2 sizes to treat the whole mouth.
The handle of these brushes is usually straight or angled with respect to the brush. Dental specialists recommend choosing the one that is most comfortable. In molar areas it is usually more comfortable to use angled designs.
In orthodontic patients, these brushes are also useful for cleaning the bracket area by inserting them under the archwire.
In case there is not enough space between the teeth, the use of dental floss or dental tape is recommended.
Interdental brushes are reusable just like a conventional toothbrush, until they become deformed. Its maintenance consists of rinsing with water after use, and, if desired, it can be dipped in an antiseptic.
