Ideal Toothbrush Toothbrushes, which serve as the main task of removing plaque used for oral cleaning, have evolved in many different ways from the past to the present and have taken their current form. In ancient times, the mechanical cleaning of the teeth was provided by animal bones, bird feathers, hedgehog spines, and cleaning sticks used in the form of biting and separating the branches of fibrous trees, which are used as miswak today. The first brush from fibrous tree branches was made in BC. It was used by the Babylonian civilization in the 3500s and it has been adopted by most societies due to its aroma, tooth-protecting natural feature over time, and its use continues today. Toothbrushes, which started to be produced with natural methods such as horse hair and pig hair, were replaced by synthetic brushes due to their high cost and high bacterial accumulation. In the American Civil Wars and World War II, American soldiers were instructed to use synthetic brushes.
