Hana Dental interdental brush

This is the Hana Dental interdental brush. I purchased this product at the dental clinic. I tend to buy oral care products there. I found that products specifically designed for dental use are effective. The spaces between my teeth always feel a bit greasy after meals, but brushing alone isn't enough to completely remove all the food debris. I recommend using an interdental brush because it is necessary not only to remove foreign substances but also tartar, and the gum massage effect helps prevent gum disease.
