Why Redheads and Dentists Don't Get Along
Nov-26-2011

Redheads may be stereotyped as having fiery tempers, but those tempers may turn to fear and loathing when they walk through the door of a dentist's office, according to research published in the Journal of the American Dental Association. The study shows that people with a specific gene that often occurs in redheads tend to experience heightened anxiety when they pop in for a regular teeth cleaning.

The details: The study's authors recruited 144 people for the study, 67 of whom were natural redheads, and 77 who were dark-haired. The participants answered survey questions about any fears or anxieties related to dental visits, and the researchers took blood samples that they later tested for specific gene variants common in people with red hair. People with one specific gene, MC1R, were more than twice as likely to report that they avoided dental appointments because of fear and anxiety than people without that gene. Of the 85 people in the study with MC1R, 65 were redheads.

What it means: It's possible, say the researchers, that redheads with the gene in question tend to be resistant to certain pain medications. This could mean redheads are more prone than most to experience a difficult dental visit, affecting their expectations about future appointments. Redheaded or not, most of us have probably had reservations about going to the dentist at some point in our lives. But don't let fear prevent you from getting your twice-yearly checkups. Recent studies have linked periodontal disease to a wide variety of chronic diseases, including heart disease, strokes, and type 2 diabetes. If it's been a while since you've visited the dentist, you might be pleasantly surprised at the experience. "Things don't hurt anymore," says Kimberly A. Harms, DDS, consumer advisor for the American Dental Association. Anesthesia has become much more effective, she says, and patients don't have to experience the pain that used to be common in dental procedures.
