Wisdom Teeth Removal

Hi Everyone, I hope you are all doing ok. I am just looking for some guidance. My son is 21, has had Addison's since he was 5 and is about to under go his first major medical procedure - the extraction of his 4 wisdom teeth. We are in Australia, so he will be under general anesthetic for this. He will meet with his endo and the surgeon beforehand but I am just looking for lived experiences and how it was managed. I am a nervous mum for the first time events!!
