The plural of toothbrush is toothbrushes. Toothbrushes are oral hygiene tools used to clean the teeth, gums, and tongue. Most toothbrushes have plastic handles that are made by injecting plastic into molds, and the bristles are made of nylon, a synthetic fiber that won’t break down in water or in the ingredients commonly used in toothpaste. Toothbrushes with alternative bristles may need to be replaced more often than toothbrushes with nylon bristles. Some toothbrushes have plant-based handles, often bamboo, and eco-friendly bristles are tougher to find. Toothbrushes are essential oral care items that have evolved over time to become scientifically designed tools using modern ergonomic designs and safe and hygienic materials.
