What is the most common age range for temporomandibular disorder (TMD)?

• A. 10-20 years
• B. 20-40 years
• C. 40-60 years
• D. 60-80 years

Answer: (B)

Temporomandibular disorder tends to appear most often in young to middle-aged adults, with the highest prevalence in the 20s to 40s. This peak reflects a blend of factors that commonly affect jaw function during this life stage, including ongoing occupational and functional demands, parafunctional habits like teeth grinding, stress-related muscle tension, and hormonal influences that can affect joint and muscle tissues. While it can occur outside this range, studies consistently show the greatest number of cases in the 20–40 age group, making this the most common window. The other age ranges have lower prevalence in comparison, though individual cases can occur there as well.
