Remedy for Toothache

First wash the mouth well with warm water, then use the following tincture: Tannin, 10 grains; gum mastic, 1/2 drachm; 10 drops of carbolic acid; dissolve in 1/2 ounce of sulphuric ether. Paint the decayed hollow of the aching tooth over with this tincture twice or thrice, using a camel’s hair brush. The tincture will remain in good condition for a month or more, provided care is taken to keep it in a vial with a glass stopper.
