From the Research
Jaw clenching can be a side effect of Unithroid (levothyroxine), particularly if your dose is too high, and you should contact your healthcare provider if you're experiencing this symptom. If you're experiencing jaw clenching while taking Unithroid, this may indicate hyperthyroidism or an excessive dose 1. Your doctor might need to adjust your medication dosage based on thyroid function tests. In the meantime, you can try stress reduction techniques like meditation or gentle jaw exercises, and avoid caffeine which can worsen clenching. Using a mouth guard at night might help protect your teeth if you're clenching during sleep. The connection between thyroid medication and jaw clenching relates to how thyroid hormones affect your nervous system and muscles - when levels are too high, it can increase muscle tension and activity.
Some studies suggest that jaw clenching may be related to stress and anxiety, which can be exacerbated by hypothyroidism or excessive levothyroxine doses 2. However, the exact relationship between Unithroid and jaw clenching is not fully understood, and more research is needed to determine the underlying mechanisms. Never adjust your Unithroid dose on your own, as proper thyroid hormone balance is crucial for many bodily functions. Regular follow-up appointments with blood tests are important to ensure your thyroid levels remain in the optimal range.
It's also worth noting that jaw clenching can be a symptom of other underlying conditions, such as bruxism, which can be related to sleep disorders or other factors 3, 4, 2. However, in the context of Unithroid treatment, it's essential to prioritize the potential relationship between thyroid hormone levels and jaw clenching, and to consult with your healthcare provider to determine the best course of action.
