Thank you for sharing your concerns about your uneven smile and TMJ. TMJ, or Temporomandibular Joint Disorder, is a condition that can affect the muscles and nerves of the jaw, potentially leading to symptoms like facial asymmetry and an uneven smile. However, it's important to note that everyone's face is naturally slightly asymmetrical, and this might be more noticeable in some people than others. The asymmetry in your smile and the difference in fat distribution could be due to natural variation, genetics, or possibly aging, which can cause changes in facial fat and muscle tone over time.TMJ disorders can indeed cause facial asymmetry, particularly if the condition has led to changes in your jaw muscles or bone structure. This could potentially affect the balance and symmetry of your facial features, including your smile.In some cases, dental issues could also contribute to an uneven smile. For instance, missing or uneven teeth, or problems with your bite alignment, could affect the way your smile looks.I would recommend you to consult with a dentist or an oral and maxillofacial surgeon, who can evaluate your condition and provide more personalized advice. If TMJ is indeed the cause, there are various treatment options available, ranging from physical therapy and medications to dental appliances or surgery, depending on the severity of your condition.
