An Improved To Cleaner
Year: 1899

page_text: I, AUGUSTUS CHARLES WILSON, of 27, Clapham Mansions, Clapham Common,
London, S.W., Advertising Agent, do hereby declare the nature of this invention
to be as follows:-
The object of my invention is to enable a person to remove the hard substances
discolouration or excrescences which form upon the teeth and which cannot be
easily removed by the ordinary tooth brush combined with powders or washes,
used for cleaning the teeth.
I carry my invention into effect in the following manner. I form a piece of
agate or like siliceous material into a suitable shape, the surface of which is
preferably highly polished, by gently rubbing such against the teeth, the
extraneous substances formed thereon can be removed without injury to the
enamel leaving the teeth in their naturally white state.
The piece of agate or like siliceous material is: mounted on a suitable stem
and may be varied in shape or size according to the requirements of the user:
The general shape is flat having a groove or hollow on one side to correspond
with the surface of the tooth.
After using the cleaner and when the discolouration and excrescences upon the
teeth have been loosened or removed the operation is completed by using an
ordinary tooth brush with a suitable dentrifrice to remove all loose pieces.

An Improved Tooth Cleaner.
1, AUGUSTUS CHARLES WILSON, of 27, Clapham Mansions, Clapham Common,
London, S.W., Advertising Agent, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
My invention relates to an improved instrument for cleaning or removing
hard substances, discolouration or excrescences from the surface of the teeth
without injuring the enamel thereof, the working portion of such instrument
being formed of a hard non-metallic substance such as agate or the like siliceous
material
The accompanying drawing serves to illustrate an instrument made in accord-
ance with my invention, in which Fig. 1 is an elevation, looking in the direction
of the working face thereof, Fig. 2 is a side elevation of Fig. l'and Fig. 3 is a
coction on ling

page_text: A is a piece of hard material such as agate or other siliceous material, having
a polished surface and which is firmly mounted in a ferrule B the latter being
attached to a suitable handle C. a is the concave or working face of the instru-
ment which may be varied in curvature according to the requirement of the
user.
The instrument is usually made in the form as shewn in the illustration, but
I do not propose to limit myself to this form, as the working portion of the
instrument could also be made with two three or more working faces cacli face
having a concave formation of different curvature, so that the various contours
of teeth can be provided for in one instrument. Also the general form can be
varied, ie, the top edge may be made convex, concave, or flat.
The instrument is used by applying the working surface to the teeth with
varying pressure, of the hand of the user, until the deposit upon the teeth is
loosened, this I have discovered by experiment is effectually performed by an
instrument of this character, and owing to its having a polished surface no
injury is caused to the enamel of the teeth. After using the cleaner when the
deposit upon the teeth is loosened, I complete the operation by means of an
ordinary tooth brush, combined with a suitable dentifrice, in order to o'effectually
remove all free particles of deposit..
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. An instrument for cleaning or removing the deposit from teeth, formed of
a hard substance such as agate or like siliceous material, mounted in a suitable
manner substantially as illustrated and for the purpose herein described.
2. An instrument for cleaning or removing the deposit from teeth, formed of a
hard substance such as agate or like siliceous material, having a polished work-
ing surface, and one more suitable concave grooves or recesses thereon, sub-
stantially as and for the purpose herein described.
