Facial Asymmetry/Bruxism

What Causes Facial Asymmetry and Bruxism? 

Both facial asymmetry and bruxism have many causes, and the cause is not always the same for different patients. For facial asymmetry, the most common causes include: 

• Developmental Abnormalities: During fetal development, disruptions or abnormalities in the growth of facial bones and tissues can lead to asymmetry. These abnormalities may result from genetic mutations, environmental factors, or a combination of both. 

• Trauma: Trauma to the face, such as fractures or soft tissue injuries, can cause asymmetry. Depending on the severity and location of the injury, it may lead to permanent changes in facial appearance. 
• Dental Issues: Problems with dental alignment or skeletal structure, such as a misaligned bite or jaw discrepancies (e.g., underbite, overbite), can contribute to facial asymmetry, as can nighttime habits such as teeth grinding and clenching, both of which are also associated with bruxism. 

Bruxism itself can contribute to facial asymmetry, although it is a separate and more preventable condition. It is often triggered by stress and anxiety, as clenching and grinding of the teeth may be a subconscious response to emotional or psychological stressors. Similarly, bruxism is often associated with sleep disorders such as sleep apnea or snoring because the repetitive movement of the jaw during grinding may be a response to airway obstructions or disruptions in sleep patterns.  

It is also important to note that both facial symmetry and bruxism may have genetic causes, and lifestyle factors can also play a major role in the severity of both conditions. Factors such as smoking, excessive alcohol consumption, and caffeine intake can all contribute to habits that lead to facial asymmetry and bruxism, as these substances can affect sleep quality and increase muscle tension, leading to grinding and clenching of the teeth during sleep.  

How to Prevent Facial Asymmetry and Minimize Bruxism 

Preventing issues that may lead to facial asymmetry and bruxism involves a combination of lifestyle changes, self-care practices, and sometimes professional interventions. First, it’s important to manage stress because stress can trigger the actions that lead to both conditions. Incorporate stress-reduction techniques, such as deep breathing exercises, meditation, yoga, and regular physical activity into your daily life. Next, reduce the consumption of caffeine-containing beverages like coffee and tea as well as alcohol, especially close to bedtime. 

Finally, take protective measures to prevent issues. If you grind your teeth at night, wearing a custom-fitted mouthguard or splint can help protect your teeth from damage and alleviate jaw tension. Dentists can provide customized mouthguards that are tailored to your bite. In addition, they can provide treatment for any underlying dental problems, such as malocclusion or misaligned teeth, as well as provide orthodontic treatments and dental restorations.
