Even though the brain reaches nearly adult size by early adolescence, it’s far from finished. The teen years are a period of massive remodeling. Neural pathways are strengthened or pruned depending on how often they’re used. This process, called synaptic pruning and myelination (insulating nerve fibers for faster communication), makes the brain more efficient but more sensitive to outside influences. THE EMOTIONAL ‘GAS PEDAL’ VS. RATIONAL ‘BRAKES’ Here’s the tricky part: The limbic system, which processes emotion and reward, develops earlier than the prefrontal cortex, the region responsible for planning, judgment, and self-control. This uneven growth explains why teens sometimes act impulsively or take risks, especially in social situations. Scientists call this the dual systems model, where their emotional “gas pedal” is pressed before their rational “brakes” are fully installed. The Science Behind Adolescent Brain Development MORE THAN MOOD SWINGS
When people think about their mouths, their teeth seem to steal all the attention. It’s what we see when we share a smile with others, and we’re always going the extra mile to ensure our teeth are straight, healthy, and white. However, there’s another part of the mouth that plays a vital role in our oral hygiene and shouldn’t be ignored. Our gums are one of our body’s primary sources of defense against harmful bacteria, as they prevent anything from entering the bloodstream while keeping teeth in place and protecting the roots. However, when our gums start to recede, they can open our mouths and bodies up to discomfort, pain, and further issues. January is Receding Gums Awareness Month , so there’s no better time to educate yourself and develop habits that keep your gums as healthy as possible. Receding gums are a serious issue that affects a significant portion of the American population and becomes more prevalent with age. Most people assume that receding gums are strictly a hygiene issue, but that’s not entirely true. While hygiene can play a role, receding gums can stem from an autoimmune disease, dry mouth caused by medications, mouth piercings, or injury to the gum tissue. To put it simply, nearly everyone is susceptible to receding gums . If you start to notice pain or discomfort near your gum line or sensitivity when brushing or consuming hot or cold foods and drinks, you may be experiencing the initial symptoms of gum recession or periodontal disease. We want to help our patients have the healthiest gums possible; that’s why we always check your gums whenever you come in for a cleaning. If you have any concerns or worries, be sure to share them with us! Also, make sure you mention if you have had recent surgery or any changes to your health, conditions, or medications. This will help us determine the source of the problem if we notice that your gums are receding. Your Gums Protect You Every Day ARE YOU PROTECTING THEM?
RISK AND REWARD While this imbalance can make adolescents more vulnerable to reckless choices,
it also makes them incredible learners. The teen brain is wired for exploration, novelty, and social connection. This sensitivity to reward can fuel creativity, adaptability, and growth.
SLEEP SHIFTS If you’ve ever noticed teens
staying up late and struggling to wake up, there’s science behind it. During adolescence, melatonin (the sleep hormone) kicks in later, shifting the natural sleep
cycle. Unfortunately, early school start times mean that many teenagers don’t get enough rest, which can hurt focus, mood, and impulse control.
Don’t take your gums for granted! They play a vital role in your overall health. Come in for a cleaning to make sure your gums are healthy!
MENTAL HEALTH TRIGGERS Adolescence is also when many mental health conditions first appear, from anxiety to depression. The rapid brain changes, hormonal shifts, and social stress make this a vulnerable period. Yet, the same flexibility that makes the brain sensitive also makes it resilient. With support, healthy habits, and stability, teens can develop strong coping skills and thrive. THE BIG PICTURE The teen brain isn’t broken. It’s under construction. Yes, it can be unpredictable, but it’s also primed for growth, adventure, and innovation. With patience, guidance, and encouragement, we can help teens channel that powerful development into building amazing futures.
