/ As a LR Dental assistant I hate saying "Any extra info or allergies before we start? " I would prefer there to be on the thing the reception asks if there's any extra info! 
/ It will say N/A if none and the info if not! I mean it would make my job way easier as most people say to me halfway through session " Oh I'm AlLeRgIc tO (BlAh bLaH BlAh)" And it's so annoying! 
next to your message if you agree and if you don't agree a ❌ ! If you are in the middle do ❌
it’s not really needed but beneficial to people
