Stopping the Rot

SIR,—I was delighted, as indeed many of my col- leagues must have been, to read Leslie Adrian's dental article (January 13). I fear, however, that either Mr Adrian was misinformed, or had perhaps misunderstood his source of information, for if there is one thing that the electric toothbrush does do, it provides beneficial stimulation to the gum tissues. The compression and release of the peripheral blood vessels that the vibrating head brings about is vastly greater than the twenty seconds' brush and spit' which the average mouth gets from the manual brush, to say nothing of the keratinising effect such a fast- moving bristle-end provides.

One of our leading periodontists has shown in a series of cases the vast benefit derived from the use of the automatic brush, even if no other treatment whatsoever is carried out. In my own practice, I have over one hundred families using this invaluable aid to dental health; the results, to say the least, are startling. For post-operative care following gingi- vectomy, the removal of diseased and useless gum tissue, the automatic brush has largely replaced the somewhat tedious but hitherto vital daily stint of stick massage—what more can be said except that next to fluoridation I consider the automatic brush the greatest advance in dental health care we have yet achieved.
