InterBrushes are fine, soft-moulded, tiny interdental rubber brushes that work as the world's smallest toothbrush. They effectively massage gums to increase circulation and remove plaque and food. The soft rubber prevents damage to gums, teeth, crowns and dental implants. InterBrush is a metal-free interdental brush, so there is no risk of damage to teeth and gums. Effectively messages gums, resulting in better blood circulation. The flexible rubber brush can adapt to any interdental space.CareDent InterBrush (Medium) X 30.
