How many ounces was a toothbrush in 1498?

In 1498, toothbrushes as we know them today did not exist. The earliest form of a toothbrush was created in China in the late 15th century, using bristles from animal hair attached to a wooden handle. Therefore, there is no specific weight in ounces for toothbrushes from that time, as their design and materials varied significantly from modern toothbrushes.
