The Claim
Oral parafunctional behaviors, including clenching and grinding, may lead to repeated injury of the masticatory muscles, which could result in chronic pain due to impaired muscle adaptation and regeneration capacity.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If you regularly clench or grind your teeth, it might keep injuring the jaw muscles, and if those muscles can't heal properly, it could lead to long-term jaw pain.
See the scientific wording
Oral parafunctional behaviors such as clenching and grinding may serve as a source of repeated masticatory muscle injury, potentially triggering chronic pain due to the muscle's inability to adapt and regenerate effectively.
What the research says
1 studyStudy: Repeated Muscle Injury as a Presumptive Trigger for Chronic Masticatory Muscle Pain
The study didn’t look at teeth grinding directly, but it found that jaw muscles heal poorly after repeated injury and become more sensitive, which supports the idea that habits like grinding could lead to long-term jaw pain.
