Can a patient with hyperthyroidism have his teeth extracted? A: If a patient with hyperthyroidism has teeth extracted, the mental stimulation and infection of the surgery may cause thyroid crisis, which may be life-threatening. Tooth extraction should be performed only after the disease is under control, with resting pulse below 100 beats/min and basal metabolic rate below +20%. Pay attention to reduce the mental stimulation of the patient and try to make him not afraid and not nervous. Do not add epinephrine to the anesthetic, and pulse and blood pressure should be checked before, during and after surgery, and pay attention to the prevention of postoperative infection.
