Mice became a rare commodity in Marro, even before the plague; doctors had realized that mice teeth seemingly keep growing throughout their lives. This power was harnessed by doctors into a common cure for toothache: mousepaste. Doctors were convinced that applying a paste of dead mouse to one's aching teeth for one to three days cures the teeth pain.
While the doctors tried to keep the recipe for the paste a secret, plenty of people in the streets tried to imitate and develop their own pastes. When dealing with persistent cases of toothache, doctors often suspect their patients to be using mousepaste bought in the streets, rather than the one they sell.
Use this whenever the toothaches, and before three days, your ache will be gone! Make sure you use it on both sides of your tooth.
Skin the mouse.
You may discard the skin and the claws of the mouse. Remove the meat from the bones.
Remove the teeth from the skull.
Chop the meat finely, until it becomes a paste.
Grind the teeth into a powder. Mix the teeth powder with the paste.
