It depends on what your dentist uses for conscious sedation, but usually a benzodiazapine and an opiate drug are used. These should not affect your adrenal insufficiency condition or your other conditions. However, you need to take your medication as usual and make sure your dentist is aware of your conditions. They may or may not recommend a consult with an anesthesiologist but I don't think it will be necessary if they just use a benzo and an opiate like most people do during conscious sedation. Hope this helps.
