from The Century Dictionary and Cyclopedia
- n. An instrument for incising the gum over a tooth, or for pushing back the gum so as to free the neck of a tooth about to be extracted. See lancet.
Sorry, no etymologies found.
That this operation is very little or not at all painful, is evidenced by the suddenness with which the infant falls asleep after the lancing, and awakes in apparently perfect health, though immediately before the use of the gum-lancet, the child may have been shrieking or in convulsions.
Then, _if it be the upper gum_ that requires lancing, you ought to go to the head of the child, looking over, as it were, and into his mouth, and should steady the gum with the index finger of your left hand; then, you should take hold of the gum-lancet with your right hand -- holding as if it were a table-knife at dinner -- and cut firmly along the inflamed and swollen gum and down to the tooth, until the edge of the gum-lancet grates on the tooth.
