Final answer:
Bartolomeo Eustachi is credited with one of the first scientific descriptions of dental nerves in his work 'Libellus de dentibus' published in 1563. However, the understanding of dental anatomy is a result of contributions from many scientists throughout history.
Step-by-step explanation:
The question 'who was the first to write about nerves in the teeth' pertains to the history of dentistry, a branch of medicine. The ancient Greek physician Hippocrates and Aristotle wrote about dentistry, including the pattern and eruption of teeth and treating decayed teeth, but the first detailed description of dental nerves is attributed to Renaissance anatomists.
Among these, Bartolomeo Eustachi, an Italian anatomist of the 16th century, is often credited with providing one of the first scientific descriptions of the dental nerves in his work 'Libellus de dentibus' (Little Book on the Teeth), published posthumously in 1563.
It is important to note that throughout history, many scientists and physicians contributed to the understanding of dental anatomy. However, specific recognition for the discovery of the nerves in the teeth is difficult to assign to a single individual due to the collaborative nature of scientific and medical discoveries.
