Yes, they do check your teeth now. Medical examiners have been told that this is a must.
Further to this, your joints and mobility are checked through certain activities - Walking on your heels....outsides of your feet, on your toes...squatting, etc.
Had my medical today, everything was spot on apart from they need to get written clarification about me not needing lanzoprozole anymore, I changed my diet and I no longer need prescribed antacids. TMU. Should only take a month tho
