For interproximal plaque control, which cleaning aid would best accomplish the goal?

• A. Round wood toothpick
• B. Flat wedge-shaped plastic toothpick
• C. Dental floss
• D. Interproximal brush

Answer: (D)

Cleaning between teeth relies on an aid that can reach the interdental spaces where a toothbrush can't. An interdental brush uses small bristles that fit into the gaps and sweep away plaque from both adjacent tooth surfaces and along the contact area, providing efficient mechanical removal where plaque tends to accumulate. This makes it more effective than a wood toothpick, which can irritate soft tissue and may not remove plaque thoroughly; a wedge-shaped plastic toothpick can also traumatize tissues and won’t clean as effectively. While floss does clean between teeth, it can miss areas on the proximal surfaces in wider embrasures or around irregular contacts, and it struggles around implants or restorations. The interdental brush is especially advantageous for areas with wider spaces, recession, or restorative work, delivering better interproximal plaque control.
