To Suck or Not to Suck, That is the Question, aka the Thumb Sucker Blues
It seems that the act of thumb sucking ignites passionate negative opinions, even though thumb sucking is extremely common and natural. In fact nearly 80% of babies suck their thumbs and have even been observed in ultrasound scans thumb sucking in the womb.
Sucking is a natural reflex for a baby that induces relaxation and calm. According to Rosemarie Van Norman , a Certified Orofacial Myologist (an expert in thumb and finger sucking),
“Thumb sucking actually makes the brain produce endorphins, which calm the body and give the child pleasure… there’s an actual change in body chemistry that takes place when a child sucks his thumb.”
Her primary conclusion is that a variety of serious problems with the developing jaw are directly linked to thumb and digit sucking, and while sucking is a natural reflex, it quickly turns into a habit that has the potential to cause problems related to the intensity and duration of sucking, and which therefore should be eliminated before the permanent teeth come in around age five.
As with all documented studies, it is hard to argue with examples and photographs, so I don’t wish to argue, but only to consider a alternative point of view.
I sucked my thumb until I was eleven, and when I stopped, it happened naturally on it’s own. I did have some of the physical problems associated with thumb sucking, such as an open bite and tongue thrusting, and I did wear braces. However, all my siblings had a similar jaw structure and teeth placement and not all of us sucked our thumbs for an extended length of time. Whatever dental malocclusion I developed as a result or not of thumb sucking has not caused me long term harm.
For an infant, sucking represents the pinnacle of safety and comfort: being held and being fed. It’s a small wonder that sucking one’s thumb would become a method of self-soothing for a new being. It’s a natural stress reliever.
Putting aside the dental problems that may be associated with thumb sucking for a moment, consider the advantages of thumb sucking. It is accessible, it costs nothing, and it is a self-directed method for managing stress. In all the literature I’ve read on the subject, I’ve never found a compelling psychological reason to eliminate this harmless stress reliever. I’ve read that children should eliminate it because it represents insecurity, but I’ve never found any writing that shows how all insecurity can be eliminated and therefore all stress eliminated.
I don’t think I’ve ever personally known anybody who didn’t experience insecurities and stresses in life. Currently the public discussion of stress and it’s relief is ubiquitous. When we encourage our children to eliminate a habit developed to manage stress such as thumb sucking are we ensuring that they have an equally harmless replacement method or strategy?
Here’s a list of the most common stress relievers: nicotine use (perhaps the most common “sucking” replacement), alcohol use, cannabis use, anti-anxiety medication, overeating, exercising and meditation. While exercise and meditation, the healthiest forms of stress relief, takes lots of practice and repetition for the habit to develop, neither one is as immediate as smoking a cigarette, having a drink or popping a little white pill. What if people were able to self-soothe with an immediate and benign option such as thumb sucking? What if it wasn’t seen as infantile, but as an endorphin producing method for inducing calm?
Can the risks of potential dental malocclusion be weighed against the benefits of thumb sucking induced tranquility? Until we can teach realistic and successful methods and strategies for managing the inevitable stresses of life, should we really be so anxious about getting our kids to stop a harmless habit which could eventually be replaced by something truly harmful? I’d love to hear what others have to say about this issue. Thanks.
