When I was medical student, world famous behaviorist Dr. Joseph Wolpe was my mentor and taught me a great deal about anxiety disorders and phobias in his clinic. I did some of the original research on agoraphobias in the mid-1970s and have used the experience to treat many patients with phobias over the last 40-plus years.

Some of these patients with phobias had marked functional impairments in their social functioning and their adaptive skills. One such example – dental phobia – is a fear of going to the dentist and is commonly found in the general population.
Susan A. Cohen, DMD, a dentist who has practiced for more than 20 years, has seen this fear on a daily basis in her patients, ranging from mild to extreme. She says that most dental patients are able to overcome their fear and panic, but she estimates that about 5% have extreme dental phobias that prevented a patient from visiting the dentist. This can lead to poor dental health, affect self esteem, and destroy relationships.
The causes of dental phobia are multifactorial and as follows:
- Fear of pain and needles.
- Past bad experiences with dental procedures.
- Past history of abuse.
- Fear of loss of control in the dental chair.
- History of other phobias or anxiety disorders.
Dr. Cohen also states that the anticipatory anxiety of going to the dentist can be just as fearful as being in the dental chair. And she further states this anticipatory anxiety causes a great deal of noncompliance in keeping dental appointments. Patients missed dental appointments that were very necessary for their overall health. Dr. Cohen noticed that triggers to this specific dental anxiety are:
- Thoughts of being in the dental office.
- Thoughts of lying in the dental chair.
- Thoughts of hearing sounds of drills or seeing dental instruments.
- The smells of the dental office.
- Dental overhead lights.
Symptoms of dental phobias include chills, dizziness, hyperhidrosis, heart palpitations, shortness of breath, indigestion, and trembling. Dr. Cohen also notes that people with dental phobias can cry before visits, have insomnia, and experience panic attacks. These symptoms can further cause avoidance of visits, and can trigger anxiety and fears that do not match the danger.
Avoidance of treatment often leads to poor dental health, periodontal disease, tooth loss, and decayed teeth, but also may contribute to heart problems, diabetes, and undetected carcinomas. Noncompliance with dental care affects general well being and self esteem, and may cause chronic pain, sleep problems, and embarrassment. It may also affect performance in work and school, and can cause social isolation.
Exposure therapy in vivo and in vitro with systematic desensitization and flooding can decrease significantly the fears, panic, and avoidance some dental patients experience. Cognitive behavioral therapy (CBT) can change the way patients see and respond to the situations that trigger symptoms.
Additionally, acupuncture can reduce the anxiety that patients feel about dental visits, and distraction techniques such as music and television can be very helpful during dental appointments. Guided imagery using deep breathing exercises with relaxation, visualization, and positive suggestion can create a sense of well-being and calmness. Hypnosis has also been shown to decrease the stress of being in a dental office. Nitrous oxide and oral or IV sedation may be a helpful last resort.
It is important for a person with dental phobias to be referred to a caring dentist who is sensitive to anxiety, and choose a dentist who will listen to and help the patient come up with signals, such as raising their hand, to temporarily stop a dental procedure. This technique will help the dental patient to avoid experiencing a total loss of control and help them feel less overwhelmed.
Dr. Cohen also says that it is helpful to visit the dentist at a less busy time of the day so there are fewer dental sounds and anxiety triggers in the office.
I have found that behavior modification with systematic desensitization and flooding in vivo and in vitro is extremely helpful in helping patients with extreme dental phobias overcome their fears and become more compliant with their dental treatments. Through the use of these techniques, dental phobias – and their emotional and physical sequelae – may be alleviated together.
