Note (30) — CANTO THIRD.
Reading edition
Tartar is more safely removed by instruments than by such chemical solvents as have been too commonly employed; for, although the injury they occasion is not at first perceptible, they ultimately disorder the substance and texture of the teeth. This is not the case when the operation is properly performed by means of instruments; and is attended with neither pain to the person, nor danger to the enamel.
The manual operation of cleaning the teeth with instruments, is not performed with equal skill and delicacy by all who practise it.—There are, of course, as many different degrees of merit in dentists, as there are in the practitioners of any other art or science.
