BONUS: Should we be using Pigs' Heads on Dental Courses?

This was recorded due to some further questions from the listeners. In this bonus listen to whether there is a place for pigs' heads on dental courses. Dr Flo is a vegan and very conflicted about the use of animals on dental courses, she has refrained from using them up to this point in her career and she chats to Dr Aly about whether they should be used or if there are any other models available!
