The age range of 15-25 years is recognized as the most prevalent for the onset of temporomandibular disorders (TMD) symptoms. This period coincides with several pivotal developmental changes in individuals’ lives. Many young adults are experiencing physical and psychological stressors associated with adolescence and early adulthood, which can manifest as TMD. Additionally, hormonal changes during these years may influence pain perception and muscle tension, further contributing to the prevalence of TMD symptoms.

In this age group, a combination of factors such as the maturation of the jaw and teeth, lifestyle changes, and potential habits like teeth grinding or jaw clenching can increase susceptibility to TMD. Understanding the demographic trends associated with TMD is essential for clinicians, as it allows for targeted preventive strategies and timely interventions for this vulnerable population.

The other age ranges presented do not reflect the highest prevalence of TMD symptoms, as the incidence tends to decrease as individuals progress into older adulthood. Thus, recognizing the 15-25 year age range as the peak period for TMD can guide practitioners in both diagnosis and management strategies for young adults.
