15 Stupid Harry Potter Movie Mistakes You Probably Missed
1. Dentists Don't Exist... But Fillings Do
To fully understand why this mistake is above them all, we have to analyse a throwaway moment in Harry Potter and the Half-Blood Prince - sorry, it just has to happen.
Professor Horace Slughorn returns to Hogwarts to fulfil the role of Potions Master and reintroduces his 'Slug Club' evening dinner events with a select number of students he wishes to 'collect' and one of this number is Hermione Granger.
Slughorn asks Hermione what her parents do for a living to which she replies that they are dentists, silencing the room. Clearly, the wizarding community has no idea what a dentist is for and that makes this final gaff the most baffling of them all.
During the Battle of the Ministry in The Order of the Phoenix, Lord Voldemort opens his mouth so wide to laugh that the entirety of his mouth is completely visible and a rather curious object appears in one of his molars: a tooth filling.
So, if wizards have no idea what dentists are for and Lord Voldemort was only resurrected into a new body less than a year before this battle... why does he having a filling!?
Surely this should have been spotted during post-production... would it have been so hard to remove it!? Really?
