There are many terms used to classify the idea of a dental phobia. It can be known as dental fear, dental anxiety, dentist phobia, odontophobia, or dentophobia. They all mean the same thing: an intense fear of visiting the dentist for dental treatment.
Dentists are a bit like Priests. People tend to go into 'confession mode' when they come into the surgery, if we haven't seen them for a while, they tell us everything. Grown men can become a nervous wreck, unsure of what's about to happen.
