Dental fear refers to the fear of dentistry and of receiving dental care. A severe form of this fear (specific phobia) is variously called dental phobia, odontophobia, dentophobia, dentist phobia, or dental anxiety. However, it has been suggested that the term "dental phobia" is often a misnomer, as many people with this condition do not feel their fears to be excessive or unreasonable and resemble individuals with post-traumatic stress disorder, caused by previous traumatic dental experiences.
