Context: So today I went to a new dentist for a checkup and cleaning . It \'s been about 2 years since I last went to one , so they had to prod all around in my mouth finding out what " previous work " I had done . Now I \' ve never really thought much of dentistry beyond the idea that it \'s like grease monkey for your mouth ; you just need to stop in every 20k miles or so . But today as this gal explored every tooth , filling and whatnot , she kept saying " Oh my , what great work ! "
Question: What may be the reason to go to the dentist ?
Option 0: To keep my feet healthy
Option 1: To keep my heart healthy
Option 2: None of the above choices .
Option 3: To keep my eyes healthy
Answer: 2
