This is what the inside of a tooth looks like. I cleaned these out because they were causing pain caused by infection.
In the middle of a tooth lies the pulp - this is made up of blood vessels, nerves and connective tissue. When this gets infected, it can cause pain/toothache. I wrote an article about this on DoctorXDentist a while back if you'd like more information :)
On a personal note, I've been really busy recently and not feeling 100% 🤒😷🤧🤢☹️ sorry for the lag in posts, especially my videos! Sooooooon :)
