Some thyroid patients may experience dry mouth, burning sensation, altered taste, gum inflammation, delayed healing, or increased sensitivity to dental stress. These problems are not the same for every patient. A patient with well-controlled thyroid levels may have a very different dental risk compared with a patient whose thyroid condition is untreated or unstable.
Why should thyroid patients inform their dentist?
A thyroid history helps the dentist plan treatment safely. The dentist should know whether the patient has hypothyroidism, hyperthyroidism, thyroid surgery history, thyroid medication, radioactive iodine treatment, palpitations, high blood pressure, anxiety, weight changes, or recent abnormal thyroid reports.
