I didn't know you were worried that 
my tooth decay might infect you.
Ich wusste nicht, dass du dir Sorgen machst,
dass mein Karies sich auf dich überträgt.
No sabía que te preocupaba
infectarte con mis caries.
Les caries sont contagieuses…
Non sapevo ti preoccupassi
che le mie carie potessero infettarti.
Eu não sabia que você estava preocupado 
 que minhas cáries passassem para você.
