To this day, my mother still recounts the unsettling story of my brother’s accident when he was just three years old. He slipped through the banisters of a department store staircase, falling two floors and landing on his chin with a heart-stopping thud.
Fortunately, it wasn’t a tragedy, but the fall did require a trip to A&E and several stitches. Beyond a small scar under his chin, we didn’t think much more of the incident at the time.
However, with recent advancements in jaw joint 3D scans and MRIs, it’s become clear that childhood accidents like my brother’s may have more long-lasting effects than we ever imagined. Emerging evidence suggests that such incidents could stunt facial growth and lead to crooked teeth, with scans now picking up on these effects in children as young as four years old.
Researchers believe head impacts can cause tears in the delicate structures of the jaw joints, triggering disturbances in the growth plates of the jaw bones. This may prevent the bones from growing to their full potential, leaving the face lopsided and the teeth misaligned or unable to meet properly.
In my brother’s case, his upper teeth became severely bucked, requiring years of braces to correct. Back then, issues like protruding teeth, recessed chins, and underbites were often thought to be purely genetic. However, new research reveals that facial development is far more complex. It is now understood that genetics alone don’t determine the way our jaws and teeth grow—other factors, such as breathing habits, tongue movement, nutrition, diet, and posture, play a significant role as well.
This deeper understanding of how facial growth works is paving the way for improved treatments. In some cases, if problems with jaw or tooth development are identified early, there are dental interventions that may even help restart the growth of a child’s facial bones. Early treatment could potentially reduce the need for more extensive procedures later in life.
What was once thought of as a simple childhood accident may have had a much greater impact on my brother’s development, and this new knowledge offers hope for better outcomes for future generations facing similar challenges.
