Dental fear (also called dental phobia, odontophobia, dentophobia, dentist phobia, and dental anxiety) is the fear of dentistry and of receiving dental care. However, it has been suggested that use of the term dental phobia should not be used for people who do not feel that their fears are excessive or unreasonable, and instead resemble individuals with post-traumatic stress disorder, caused by previous traumatic dental experiences.
It is estimated that as many as 75% of US adults experience some degree of dental fear, from mild to severe. Approximately 5 to 10 percent of U.S. adults are considered to experience dental phobia; that is, they are so fearful of receiving dental treatment that they avoid dental care at all costs. Many dentally fearful people will only seek dental care when they have a dental emergency, such as a toothache or dental abscess. People who are very fearful of dental care often experience a "cycle of avoidance," in which they avoid dental care due to fear until they experience a dental emergency requiring invasive treatment, which can reinforce their fear of dentistry.
Women tend to report more dental fear than men, and younger people tend to report being more dentally fearful than older individuals. People tend to report being more fearful of more invasive procedures, such as oral surgery, than they are of less invasive treatment, such as professional dental cleanings, or prophylaxis.
Direct experience is the most common way people develop dental fears. Most people report that their dental fear began after a traumatic, difficult, and/or painful dental experience. However, painful or traumatic dental experiences alone do not explain why people develop dental phobia. The perceived manner of the dentist is an important variable. Dentists who were considered "impersonal", "uncaring", "uninterested" or "cold" may develop high dental fear in patients, even in the absence of painful experiences, whereas some patients who had had painful experiences failed to develop dental fear if they perceived their dentist as caring and warm.
Phobia of dental care is sometimes diagnosed using a fear measurement instrument like Corah's Dental Anxiety Scale or the Modified Dental Anxiety Scale.
