Manage with interproximal floss and interproximal brushes.

Brushing alone doesn't effectively remove plaque.

This gap is also wide enough to only use dental floss.

I use interdental floss and interdental brushes.

Follow the dentist's instructions: first use interdental brushes and dental floss, then brush your teeth.

It feels like my mouth is becoming cleaner.

I bought this product at a pharmacy, and it seems to be made by a domestic company and exported to Japan.
