Gintoki’s mouth is swollen like crazy, forcing him to go to the dentist for treatment. Unable to cope with the stress and pressure of waiting, a crazed Gintoki screams for someone to just kill him and be done with it. After getting scolded by the staff, Gintoki waits for his turn when another man with a swollen mouth comes in, making things even more complicated!
Look, they even included a toothbrush!
Miren, incluso me pusieron 
un cepillo de dientes.
Olha, eles até incluíram uma escova de dentes nova em folha!
