Is Your Right Cheek Bigger? Jaw Muscle Development - Dentistry

More Info

---

When it comes to the development of jaw muscles, particularly the masseter muscle, it's not uncommon for individuals to notice asymmetry in their facial features, such as one cheek appearing larger than the other. This can often be attributed to habitual behaviors, such as chewing predominantly on one side of the mouth. In your case, since you mentioned that you tend to chew more on the right side, it is likely that the masseter muscle on that side has become more developed compared to the left side, leading to the appearance of a larger cheek.

The masseter muscle is one of the primary muscles involved in chewing and is responsible for elevating the jaw. Overuse of this muscle can lead to hypertrophy, which is an increase in muscle size. This can happen if you consistently chew on one side, as the muscle on that side is being exercised more than the other. Additionally, other factors such as teeth alignment, jaw posture, and even stress-related habits like teeth grinding (bruxism) can contribute to muscle development and facial asymmetry.

If you are concerned about the size difference or if it is causing discomfort, there are several approaches you can consider:
1. Balanced Chewing: Try to consciously chew on both sides of your mouth. This can help to promote more balanced muscle development and may reduce the prominence of the larger cheek over time.

2. Jaw Exercises: Engaging in specific jaw exercises can help strengthen the muscles on the weaker side and promote symmetry. Consult with a physical therapist or a dentist who specializes in orofacial pain for tailored exercises.

3. Dental Evaluation: It may be beneficial to have a dental evaluation to check for any underlying issues such as misaligned teeth or jaw problems that could be contributing to your chewing habits. An orthodontist may provide options for correcting any alignment issues.

4. Stress Management: If you suspect that stress is leading to teeth grinding or clenching, consider stress management techniques such as mindfulness, yoga, or other relaxation methods. A night guard may also be recommended by your dentist to protect your teeth and reduce muscle strain.

5. Consult a Specialist: If the asymmetry is significant or if you experience pain or discomfort, it may be wise to consult with a healthcare professional, such as an oral and maxillofacial surgeon or a dentist specializing in temporomandibular joint (TMJ) disorders. They can provide a thorough assessment and recommend appropriate treatments.

In summary, the asymmetry in your cheeks is likely due to the overdevelopment of the masseter muscle on the right side from habitual chewing. By making conscious efforts to balance your chewing habits and seeking professional advice if necessary, you can work towards achieving a more symmetrical appearance. Remember, changes in muscle development can take time, so be patient with the process.
