Dustin’s tooth had been bothering him for weeks. Every time he took a bite of food, drank something cold, or even spoke, a throbbing pain would shoot through his lower jaw and up into his skull. He had been silently living with the pain for so long because he did not want to have to go to the dentist. It was not that he was afraid of the pain. That did not really bother him. He knew that the dentist would tell him that his tooth was hurting because he was not brushing his teeth regularly or taking care of his gums. The dentist could not really do much about that, but he could tell Dustin’s mom.
Dustin could not remember the last time he brushed his teeth or used mouthwash, but he could remember that he told his mother that he did both the night before, and the night before that, and the night before that. If she found out that he had been lying about brushing his teeth and using mouthwash for months, if not longer, she would fly into an uncontrollable rage.
Dustin knew he had to think of a plan. He could not tell his mom that his tooth had been hurting for weeks because then she would ask him why he waited so long to tell her. How would he explain that? Also, he could not casually bring up going to the dentist because that would make his mother suspicious. What 11-year-old boy asks to go to the dentist? No, neither of those would work. He had to think of something that was equal parts sneaky and honest.
After hours of work, he came up with a plan that was neither. He knew that his mom was cooking chicken that night, so he decided to pretend that he broke his tooth on a chicken bone. He was convinced that his plan was foolproof. So, as he ate supper that night, he waited to catch his mother looking at him as he was putting a piece of chicken in his mouth.
Upon finding the perfect opportunity, he crunched down on the chicken bone and began screaming, "Ow, my tooth! My tooth! I think I broke it. Oh, I broke it. I broke it on the chicken bone that was just in my mouth a second ago. Oh, I broke my tooth on a chicken bone!"
Dustin then looked over at his mother, expecting to see a look of concern, expecting to see her running towards him, but he saw neither. Instead, he saw her sitting calmly and then heard her say, "That’s odd. I’ve never seen a person have pain during the weeks leading up to breaking his tooth. I guess strange things happen when you go a whole year without brushing your teeth!"
