Colgate toothbrushes are manufactured in Sanxiao, China. According to Colgate, the factory in which the toothbrushes are made is the largest in the world. Colgate's toothbrush plant manufactures approximately 1.4 billion toothbrushes each year, including both manual and electric brushes.
Colgate toothbrushes are designed with plastic, rubber and nylon. Early toothbrushes date as far back as 3000 BC when Egyptians and Babylonians brushed their teeth with frayed sticks. In China, early toothbrushes were designed with pig bristles and bamboo.The first bristle toothbrush was created in 1844. Toothbrush bristles consisted of natural horsehair or pig bristles until nylon was invented. In 1939, nylon bristles replaced natural bristles and are still used today.
