toothbrush

A toothbrush is a personal hygiene tool, not a culinary ingredient. It consists of a handle (traditionally made from wood, bone, or plastic) with bristles (historically natural animal hair, now typically synthetic nylon) designed for cleaning teeth and oral cavities. Toothbrushes are implements for dental care and have no place in food preparation or consumption.

A toothbrush has no culinary applications and should never be used in food preparation. It is exclusively a dental hygiene tool. Any contact between a toothbrush and food or cooking surfaces would constitute contamination and a food safety hazard.
