Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. It is possible, based on your description, that Monkey broke a tooth yesterday when he bit the person as puppy teeth break quite easily. I would recommend having a veterinarian examine him so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
