Dental Phobias

Have a Phobia? It could be in your DNA

Dentistry is deep rooted in our history dating all the back to 7000 BC - no pun intended.  The history of dental health was about cure not care with not much in-between other than extraction and some drills that we don’t dare think about. Dental health wasn’t something that was regarded of great importance even though it brought great suffering, I mean, anaesthetic was only invented in 1846. Ouch.

With no such thing as pain-free dentistry, botch-ups and no infection control, this meant that for hundreds of years dentistry for our ancestors was a bloodied, agonising suffering, with a chance of death (not putting in lightly). In comparison to dentistry today, ancient dentistry is not in any way the same ‘practice’. Thank God. But something that is the same or can be the same is the fear associated with going to the dentist.

Fears, Phobias and Anxieties

Fears, phobias and anxieties are something that many of us still can’t shake when even thinking about seeing a dentist, regardless of how far we have come in dental care. Many people don’t go to the dentist regularly, or worse, avoid the dentist altogether. But what if there was more to our fears than labelling them totally irrational? Perhaps there’s more to them than we know…

New studies and research have developed which suggest that memories or fears can be passed down to children and their children and their children’s children (and so forth) through genes. Science has long debated the nature vs. nurture; however, new research has explained how seemingly ‘irrational’ or ‘random’ phobias can develop which are not taught or developed through learned experiences.


A Nature Neuroscience study has shown that it is possible for some information to be inherited biologically through chemical changes in our DNA. This would suggest that ancestral experience before conception can later influence our adult behaviour.

The team at the Emory University School of medicine, in the USA, conducted an animal study using mice. The mice were ‘trained’ to fear a smell similar to cherry blossom. The team investigated what was happening to the cells during fertilisation. They discovered that a section of DNA responsible for sensitivity was made more active in the mice’s sperm.

They found that both the mice’s offspring and their offspring were extremely ‘fearful’ or ‘trepidations’ about the cherry blossoms scent and would try and avoid the scent, despite not being trained or experienced a reason to be fearful of it in their lives.

They also found that there were changes in the brain structure which concludes evidence of ‘transgenerational epigenetic inheritance’. To you and me this means phobias or fears based on an external experience, can be internally passed down through genetics to affect later generations behaviour without them experience anything similar in their lifetimes.

What makes this study so interesting is that we share around 95 percent of our working DNA with mice. This is evidence enough to suggest that this could be the same case in humans and explain irrational or random phobias that we experience. Therefore something traumatic that happened to your great great grandmother before she had your great-grandmother, could have continually been passed down through DNA which could affect you today...

Back to Dentistry

This means that because there is such a traumatic history associated with dentistry, these fears or bad experiences could be passed down through genetics. This could be why many people share the same phobia associated with dentistry today. These phobias, anxious feelings and very real physical symptoms could, in fact, be rational in the sense that they are a ‘family affair’, rooted in your DNA which have caused these fears.



We talk about dentistry today. Dentistry today is nothing like it was in the past; your Barbour is not doubling up as your back street dental surgeon. Dentistry is a trained and respected, regulated, profession. Dental care is now about patient-focused care; which means an exceptional level of care, patient comfort, expert treatment and pain-free procedures. Dental health, as well as dental care, is improving every day, not only is it about cure but it is also about prevention.

Caring for your teeth and maintaining good oral health has become the forefront of dentistry.  Many dental health centres recognise patient’s fears and phobias and try to combat them and relieve them through additional services such as I.V. sedation dentistry.
