Based on available data, TMJ disorders (TMD) affect a notable percentage of the general adult population, with specific groups having a higher likelihood of experiencing the condition.
Understanding Who is Affected by TMJ Disorders
Prevalence data indicates that between 5% and 12% of adults in the general population experience some form of TMJ disorder. This means that millions of people are affected by issues related to the jaw joint and surrounding muscles.
Key Demographics More Likely to Develop TMJ Disorders
While TMD can affect anyone, certain demographic groups show a higher prevalence:
- Gender: The condition is approximately twice as common in women and people assigned female at birth (AFAB) compared to men and people assigned male at birth (AMAB). The exact reasons for this difference are still being researched but may involve hormonal factors, anatomical differences, or variations in pain processing.
- Age: Individuals between the ages of 20 and 40 are the most likely demographic to develop TMD. This peak age range suggests that factors related to activity, stress levels, or early signs of joint changes might play a significant role during these years.
To summarize the key populations affected:
| Demographic Group | Likelihood of TMJ Disorder |
|---|---|
| General Adult Population | 5% to 12% affected |
| Women / AFAB | Approximately twice as common as men/AMAB |
| People aged 20–40 | Most likely age group to develop TMD |
It's important to note that these are statistical likelihoods. People outside these groups can and do develop TMJ disorders.
