Justin is 16. Justin went through puberty early and appears older than he really is. One day after school, Justin gets in a fight with another teenager. Justin is punched in the mouth and his teeth are hurting. Justin does not want to tell his parents because he is afraid he will get in trouble for fighting. As such, Justin goes to a dentist on his own. He tells the receptionist that he fell down his stairs and landed face-first. She asks him for insurance and Justin replies that he does not have any. 

The receptionist then has Justin sign a contract in which he agrees to be responsible for the charges for his dental work. At no time did the receptionist ask Justin how old he was. Justin has some dental work done and a bill for $882 is sent in the mail about 10 days later. Justin ignores the bill because he does not have $882. The dental office calls Justin and tells him that the office will sue him for breach of contract if he does not agree to a payment plan. Justin refuses to pay and tells them he is only a teenager. The dental office comes to you for help. 

Does the dental office have a breach of contract claim against Justin? Explain your answer.
