Dental Fears - This Won't Hurt (or Will It?)
Although nobody loves a trip to the dentist, most of us go because we
want to preserve our health as well as the luster of our pearly
whites. However, the American Dental Association (ADA) estimates that
35 million adults have so much anxiety about dental visits that they
worry, postpone or avoid seeing their dentist.
Studies conducted by faculty at the University of Washington Dental
Fears Research clinic in Seattle indicate that the prevalance
of dental fear throughout the world is about 20 percent. Peter
Milgrom, DDS, director of the clinic, said that the level of dental
fears peaks around middle age.
How do you know if you've crossed the line from just disliking
the
dentist or what the dentist is doing to dental fear?
Dr. Milgrom answered that: "The issue is whether a person
can maintain their dental health, use a dentist if needed, without
terrible foreboding or running away."
Dental Fears from History of Sexual or Physical Abuse
The most common dental fears relate to pain, fear of allergic
reactions to local anesthetic or drilling. About two-thirds of dental
fears come from direct experience, usually during childhood.
Sometimes dental fears are associated with other mental health
conditions. "For example, patients with a history of sexual or
physical abuse will often be afraid of being tipped backwards, losing
control," said Milgrom.
There is evidence that fear of pain actually hurts. Researchers at
Oxford University monitored the brain activity of 12 test subjects
who felt a series of painless warm and painful hot sensations on
their left hand. Each experience was signaled ahead of time by a
colored light. The researchers reported in the June 18, 1999 issue of
the journal Science that they discovered subjects' brain sites
activated by the expectation of pain were distinct from, but located
close to, those activated by the actual encounter with pain. As for
Milgrom, he says "people who are afraid are not good estimators of
pain. They tend to overestimate it."
Drugs Don't Cure Dental Fears
Overcoming dental fear is more effectively done through behavioral
changes rather than drugs, Milgrom said. "There is no evidence that
drugs cure fear," he said. Dentists need to give patients a safe,
step-like introduction to the things they are afraid of much the way
that parents help children overcome fears of, say, swimming.
The first step for patients is to share feelings with the dentist.
Sometimes, it's helpful to schedule a pre-treatment appointment
to
talk about specific fears. Dentists can explain each step of a
procedure or examination. The more you know about what will be done,
the more relaxed and confident you will be. Most dentists will agree
to take breaks during a procedure if they can through a pre-arranged
signal.
Practicing distraction or relaxation techniques to take your mind off
of the procedure can help reduce tension. Milgrom suggested that
these skills can be transferred from other aspects of life such as
childbirthing classes or techniques previously learned to control
muscle tension.
If pain is the issue, Milgrom recommends extra local anesthetic and
nitrous oxide. Being friendly and sociable, having regular visits to
the dentist can also improve feelings of trust and reduce fear.
Dental fear can be overcome. You may not leave the dentist's
office
smiling and joyous, but you can rout fear and take care of your
dental health.
