Self-scaling with an interdental brush

Interdental brushes are the same product, so they are divided into several sizes.

It is said that in this case, you must carefully select and use a size that fits your teeth to avoid putting strain on your gums.

My teeth aren't spaced far apart, and since I don't use them much, I am using the smallest size.

However, it has the disadvantage of bending too easily with frequent use.

Also, since there aren't many lids, it is a bit inconvenient to store, but it is good for removing tartar, so I am using it well.
