There are a number of routine tasks that can make people fell nervous - from calling to make a doctor's appointment to getting your eyes tested.
Another thing that may fall under this category is dentist check-ups, as many people may find having someone prodding about in their mouth quite uncomfortable.
As such, some people might end up acting rather awkwardly or out of the ordinary when they attend their appointments and it seems one dentist has seen his fair share of unexpected behaviour at his clinic.
