Wearing braces is a transformative step toward a healthier smile, but it is common for individuals undergoing orthodontic treatment to experience noticeable lip dryness. The presence of new hardware creates physical changes that directly impact the delicate skin of the lips. Understanding the root causes allows a person to effectively manage this widely expected side effect.
The Mechanical Reasons for Increased Lip Dryness
The introduction of brackets and wires into the mouth physically alters the resting position of the lips. This hardware forces the soft tissues to rest tautly over the appliance, slightly stretching the lips and making it difficult to maintain a complete seal at rest. This altered posture can lead to a condition known as lip incompetence, which is the inability to comfortably keep the lips closed without muscle strain.
The most significant factor contributing to dryness is increased involuntary mouth breathing, especially during sleep. When the lips cannot seal naturally, the constant rush of air over the oral tissues and lips causes moisture to evaporate rapidly. This continuous airflow mimics a harsh, dry environment, accelerating the loss of hydration from the superficial skin layers.
Orthodontic appliances can also create minor friction against the inner surface of the lips and cheeks. This rubbing action can cause slight irritation to the soft tissue, which may prompt a person to unconsciously lick their lips in response to the feeling of discomfort or altered saliva flow. Although licking provides momentary relief, the enzymes in saliva strip the natural protective oils from the lips, leading to further dehydration and chapping.
Immediate Relief and Treatment Strategies
When lips are already chapped and irritated, the immediate focus should be on creating a protective barrier to lock in existing moisture. Highly effective products are those that contain occlusive ingredients, such as petrolatum, mineral oil, or beeswax. These substances form a physical seal over the lips, preventing further moisture loss through evaporation and shielding the skin from the constant airflow caused by mouth breathing.
While humectants like hyaluronic acid or glycerin attract water, occlusives are generally more beneficial for the specific, severe dryness caused by braces because they offer a stronger protective shield. Avoid balms containing common irritants, such as camphor, menthol, or artificial flavors and fragrances. These components can initially feel soothing but may ultimately increase irritation and inflammation on already compromised skin.
The application frequency is just as important as the product choice for managing symptoms. A thick layer of balm should be applied frequently throughout the day, particularly after eating or drinking, which can wipe away the protective layer. Applying a generous amount right before bed is particularly important to protect the lips during the long period of potential overnight mouth breathing. A high-quality lip product containing an SPF of 15 or higher is also advisable, as sun exposure can exacerbate dryness and irritation.
Long-Term Habits and Associated Concerns
Addressing the root cause of moisture loss requires consistent systemic and behavioral changes. Maintaining high water intake throughout the day is a powerful preventative measure. Internal hydration supports the skin’s ability to retain moisture and helps combat the continuous loss of moisture from the mouth and lips.
Consciously practicing nasal breathing when awake minimizes the drying effect of air flowing directly over the lips. While this may be challenging initially, focusing on keeping the lips gently sealed can reduce the frequency of involuntary mouth breathing episodes. This habit trains the perioral muscles and can significantly lessen the need for constant topical treatment.
Braces-related dryness can sometimes be complicated by angular cheilitis, which are painful cracks that form at the corners of the mouth. This condition is often caused by saliva pooling in the corners, which is exacerbated by lip licking or the altered posture of the mouth. If these cracks become red, infected, or fail to heal with regular balm application, it may indicate a fungal or bacterial infection requiring prescription antifungal or steroid creams from a dentist or physician.
