“Do Redheads Feel More Pain?”

Redheads feel more pain! New research published in the July 09 Journal of The American Dental Association found that painful experiences at the dentist might cause more anxiety for men and women with red hair, who were twice as likely to avoid dental care than people with dark hair. Red-headed children or adults might avoid dental visits and might be at a higher risk of affecting their dental health!

A child that has an unfounded fear of the dentist (or even a founded one, instilled by parents who aren’t very fond of their dentist or past experiences in the dental chair) are common, however due to a scientific quirk (thanks to mother nature), redheaded individuals do feel pain more intensely than non-red-headed persons. These extra sensitivities to pain might lead to negative experiences with dental visits, which as being parental health care providers, we should be aware of these phenomena.

There are two studies that exist. In 2004, research showed that people with red hair need twenty percent more general anesthesia than blonds or brunettes. A 2005 study indicated that redheads are more sensitive to thermal pain and are more resistant to the effects of local anesthesia. Researchers believe variants of the melanocortin-1 receptor gene play a role. This MC1R gene produces melanin, which gives skin, hair and eyes their color.

While blond, brown and black-haired people produce melanin, those with red hair have a mutation of this receptor. It produces a different coloring called pheomelanin, which results in freckles, fair skin and ginger hair. About 5 percent of whites are estimated to have these characteristics. The relationship between MC1R and pain sensitivity is still under study, researchers have found MC1R receptors in the brain and some of them are known to influence pain sensitivity. Non-redheads can also carry a variant of the MC1R gene. In this dental study that had 144 participants, about a quarter of the non-redheads had variants of the MC1R gene. These people also experienced heightened anxiety and avoided dental care compared with others who did not have the variant. There is no commercial test available for variations of the MC1R gene.

The best tips for redheads are to work on the prevention of dental problems, inform your health provider that you are highly sensitive, use TLC and be patient, wait a bit longer to let the anesthesia start to work and finally inform your doctor that you might require additional amounts of local anesthesia – because you are a special redhead!
