As is probably widely known Ryanair doesn’t provide Aircraft Security Cards. The content of the security card is printed on the back of the seat.
While descending into Dublin I noticed that the information provided by Ryanair stated that in cases of an emergency landing you should take off your glasses and take out your third teeth as well.
I cannot remember that any other airline advised its passengers to take out their dentures in cases of emergency. But it’s possible that I never studied the aircraft security cards properly.
