TOOTH CLEANING DEVICE Filed Jan. 18, 1961 mid" INVENTOR.

l7 ADOLPH Q IV/SEMAN BY W 9 M AT TORNEVS 3,101,727 T TH CLEANING DEVICE Adolph D. Wiseman, 1075 Baker St., San Francisco, Calif. Filed Jan. 18, 1961, Ser. No. 83,573 2 Claims. (Cl. 132-93) This invention relates to a tooth cleaning'device, and

is a'continuation in part of application fior United States Letters Patent, Serial No. 803,735, filed April 2, 1959, and now abandoned. v 2 i 1 -One oi-the objects oi-the invention is thevpnovision of a tooth cleaning device that is adapted to meet any interdental cleaning requirement tor entire dentition.

Another object of the invention is the provisionoi a tooth cleaning device having a pair of picks stationarily and integrally connected with a supporting'body adapted to be firmly gripped between the thumb and forefinger of a handlof a user, and which body is formed to properly position the device between said fingers for proper use of the device.

- A still further object of the invention is the provision of a one piece, integral device that includes av pair 'of toothpick-s respectively adapted to be safely used by a layman for elficient interdental cleaning, and for entering and cleaning exposed bifurcations and trifurcati ons and atypical areas anywhere in the mouth from the outer as well as the palatal and lingual aspects of'the'upp'erand lower teeth, all oi which operations may be accomplished while holding the )devicein convenient positions from the front of the mouth; and without uncomfortable distortion of the mouth. r

Another object orfthednvention is the provision of a one-piece cleaning device.;that includes picks adapted to be bent and twisted to anyd'esired shape. for reaching any desired point within the mouth: and which: picks will be in the most efficient shape for cleaning at said point when they are used, and which device includes a finger grippable body adapted for. holding the picks and for manipulating them when they areused in a cleaning I operation.

The toothpick of this invention is particularly designed fior use by the layman who, in virtually all instances,

makes no attempt to see, through the use of a mirror,

. the area or points where the pick is to be used and who would not be able to effi cien-tly manipulate the pick through observing the image on the mirror even if .the

point or points oouldbe observedin that manner, which is not always possible.

The professional metal scale'rsland probes used by the dentist, such'as shown'in US. Patent No. 1,446,906, of February 27,1923, to W. A. Kelsey, and others known to the dentaltprofession, would-be dangerous in the hands of a layman and would belikely to cause more injury to the teeth and gums than any benefit.

Few attempts have been'made to provide the layman body, as will later'bepxplained.

with a toothpick that is safe, sanitary and unbreakable,

and that is adapted to conveniently reach points heretofore deemed tobe substantiallyinaccessible to any but a dentist, or by use of the ordinary toothpick. Such attempts as have been made are toothpicks of metal 'or other hard material slidable a handle much longer than the pick or hingedly connected with a handle tor jack knife folding and which handles notonly act as 3,101,727 Patented u 27, 1963 used, and will not cause injury to fillings or nerve shocks due to electrolytic action resulting from engagement of a metallic pick with the metals of fillings.

ings. I

In the drawings,

FIG. 1 is a side elevational View of .the tooth cleaning device; the dot-dash lines indicating some of the positions to which the picks may be bent for use.

FIG. 2 is atop plan view, of the pick of FIG. 1; the dot-dash line-s indicating other possible defiormations of the picks. 1

FIG. 3 is a perspective view of teeth of the lower jaw with the picks of FIG; 1 shown in two positions in which said picks have been distorted for more efliciently reaching certain points, one device, of the two illus- I tratedbeing shown held between the digital pul-ps of the thumb and! forefinger of ,a hand and Iwhichpulps wouldnorrnally' cover the finger gripping portion of the device illustrated.

a pair or teeth. v

In detail, the toothpick comprises a central, generally oblong,-disc-like body 1 having flattened opposite sides 2 andrelativelynarmow flanges 3 projecting oppositely outwardly from said; sides around the edges of said body whereby said body will have oppositely outwardly facing recesses at opposite sides thereof which the thumb and forefinger of the user are adapted to seat. This substantiallyprecludesaocidentalrotation of the device in a plane perpendicular to that of the disc. Slight protuberances, 4- of' any design may be formed on the bottom of said recesses which will also contribute to the degree of firmness with which'the device may be gripped. Whileitisto be understood'that the invention is not to be restricted to any particular dimensions, it has been found that a body approximately three quarters of inch in length and approximately one-half of aninch in width, with ajthickness of about one-eighth of an inch between the outer edges of the flanges, has been satisfactory. These dimensions provide a firm/finger gripping portion within the outlines of the flanges 'at opposite sides of the body-for using the picks'thatare integral therewith and that project from {It is pertinent to mote that the flattened body is of generally the sameya'rea and" shape of thedigital pulp or pad of the thumb and forefinger of a hand, thereby substantially insuring against accidental slippage and movementor droppying of the device when the body is properly held between the thumb'and forefinger. This fio-nnand vdimension oi the body 11 alsoenables the user to quickly collectors for dust and dirt into which the pick is seated when not iii-use, but the picks are limited to use in certain areas due to their permanent shapes and to the character of handles connected therewith.

The tooth cleaning device of the present inventionovercomes all of the objectionsto prior devices intended for similar purposes and provides a tooth cleaning device end portion 9 :that is preferably cylindrical, and of arotate the body to:v change the end to end relation-thereof,

thus changing the positions of picks that project from its ends, without accidentally dropping the device. When it is considered that a dropped tooth cleaning device'is not, or should not be used thereafter unless sterilized, the importance of a structure that minimizes the chance of its being accidentally dropped, is' quite important. a The opposite ends of the body 1 are :desigriatedS and '6, these being defined by the edges of shortest length.

Projecting inom end edge 5 centrally between the-ends thereof, is one toothpick generally designated 8. :This pickis integral with the. body 1 and comprises an inner Other-objects and advantages will appear in the. drawthe aids of the 3 diarneter that is approximately equal to the thickness of body 1. This portion 9 is coaxial with the longitudinal axis. of body 1.

The outer end portion 10 of the toothpick is elongated with inclined sides terminating in a point 11. T his outer end portion is cylindrical in cross sectional contour and is connected with the inner end portion 9 by'an intermediate goose-neck portion 12, also cylindrical in cross sectional contour, and in a manner so that the longitudinal axis of the outer end portion 10 intersects the longitudinal axis of body 1 and portion 9 at an angle which may be approximately thirty to forty-five degrees at the same side of axis 9 as the goose neck portion 12, and the point 1'1 is directed generally outwardly of the body 1 as seen in FIG. 1. The upper end of portion .10 forms part of the goose neck 12, and the other part of the goose neck, designated 13, extends from said upper end to the inner end portion 9 with which it is connected.

Preferably substantially the entire pick '8 is disposed between parallel lines, in extension of the upper and lower edges of the body 1, which are the longest edges, and the corners of the body are rounded.

The overall length of the pick 8 as seen in FIG. 1, is only slightly longer than the length of the body.

At the other end of body 1 that is opposite to pick 8, is a second toothpick generally designated 14. This pick '14 is generally in the form of a straight [knife blalde having a reinforcing fillet at the juncture between the pick and body 1.

The cross sectional contour of blade 14 is seen in LFIG. 4 and generally conforms to the outline of the interdental spaces with the sharp edge 16 of the blade directed away from the gum, so that the [flat back edge 17 will massage the gum, rather than tend to out into it, when the blade is inserted between the teeth.

The back edge 17 of the blade 14- is straight, and the outer end portion of sharp edge 18 curve to meet the straight back edge. e v

The length of pick 14 is substantially'the same as the length of pick 8 and is coaxial with the portion 9 of pick 8 and with the longitudinal axis of the body, hence the device as. a whole is substantially balanced when the body 1 is properly gripped between the thumb and forefinger of a hand. When saidbody-portion is gripped between the thumb19 and forefinger 20 of a hand, one of the picks will normally project outwardly of the hand generally in a direction in outwardly extension of the thumb 19, while the outer pick will project toward the hand, but said other pick will not under any condtionof use engage the hand.

Thus, while the dimensions already given by way of an example are not intended to be restrictive, the overall maximum length of the device should be such that the device can be freely rota-tedthrough 360 without having either of the picks engage the hand when the pulps of the thumb and forefinger engage the opposite sides of the body '1 on the central transverse axis-[of the body.

The entire device is molded from a polyethelene plasform after bending it to enable inserting it between the teeth.

In view of the foregoing description it is apparent that conventional tempered scalers and the like would be inoperative for accomplishing [the results of the present invention, nor are such instruments intended or suitable tfior such use, and they are particularly unsuited for use by anyone but dentists.

In FIG. 1 the dotdash lines 21, and the full line position of the upper device indicated in FIG. 3 show the pick '8 in a position to readily enter the interdental spaces at the lingual side. I

. Dot-dash'line' position 22 indicates the portion 11) bent to project generally in alignment with the longitudinal axis :of the body 1, and blade 12 may be bent in the plane thereof above and below said axis as seen in dot-dash lines 23', 24 (FIG. 1) or to either side as seen in dotdash line (FIG. 2) or either of the picks maybe bent'to the bayonet shape indicated by \dotdash lines 25 of FIG. 2. Dot dash lines 26, 27' (FIG. 2) show pick 8 bent to either side of the longimdinal axis of the body .1, and blade 14 in full line in FIG. 3 is bent substantially at a right angle to the longitudinal axis of said body to enter the interdental space between posterior teeth.

tic of the type in which the picks are adapted to be bent to any desired degree, twisted, or otherwise distorted to enable reaching any desired point along either side of any of the teeth and to perform the desired cleaning action at such point. Also, the plastic, while hard, is relatively soft compared to metal, and when the picks are bent or distorted to the desired "degree, they will retain a bent or distorted shape during the cleaning operation instead of springing back to the original form, which is a highly desirable characteristic since a rapid reooveryof a toothpick, after being bent, would be undesirable since it would not only defeat the result intended-to be accomplished by bending or distorting the pick, but the pick could place an undesirable tension on teeth at opposite sides of .the pick, whenthe latter was between them, if it were to rapidly return to its original Either edge of blade "14 may be directed upwardly, and obviously the body 1 may be held in any desired position.

One pick will not normally perform a complete proper cleaning portion, and the provision of the recess opposite sides of body '1 enables quick and easy rotation of the body about its axis that is perpendicular to the longitudinally extending axis thereof without danger of dropping the pick as has heretobefo're been mentioned. [For example, pick 8 will readily clean the interdental spaces between the upper'anterior teeth at either side of the row of teeth, and then the body may be quickly rotated to swing pick 14 to position for cleaning the interdental spaces between the lower anterior teeth at the outer side of the row thereof.

In some instances the pink 8 or pick 14 may be twisted so that the points will readily reach certain points and areas that cannot otherwise be reached.

By bending the picks, as above-noted, the pointed ends Will not only reach areas that cannototherwise be reached, but this can be accomplished without distorting the mouth uncomfortably, since the fingers will be in the anterior portion thereof, and the cleaning can be effected without likelihood of injury to the tissue within the mouth, such as frequently occurs Where :an entire rigid, elongated pick is inserted into the mouth in anattempt to obtain the desired angle essential to reaching a point that is relatively inaccessible to such pick. Near fatal serious accidents have occurred where accidental closing of the mouth has forced the pick into the palate or where an awkwardly positioned pick, due to its rigidity and length, has become lodged in the throat due to accidental dropping of the rigid pick through an insecure bold thereon when an attempt is made to manipulate it in an awkward position. The fact that the picks of the presentinvention are flexible;'their points would tend to preclude any likelihood of serious injury were the picks to be stabbed into the tissue, but the main factor that makes them safe, is the fact that they are readily formed to be manipulated in relatively inaccessible places from positions of the fingers in .the mouth or at the front of the mouth, where there is to the toothpicks. There are no slides, hinges, pockets or moving parts to become unsanitary and to clogor gather dirt and the like.

By slightly roughening the surface of portion 10 of pick 8, and the sides of pick 14, the frictional resistance to movement of the picks against the teeth is increased, and some persons desire this. structure. It is to be understood that the grooves indicated in FIG. 1 on the point portion 1t? and on the sides of pick 14 are not deep enough to retain foreign matter therein, nor do they noticeably weaken the picks, but they are not essential to a normal teeth cleaning operation. Where longitudinal movement of either pick when it is between adjacent teeth is caused, the roughened surfaces will have a slight abrasive effect, except there will be no injury to the teeth, and a more pronounced massaging of the gums by pick 8 will result.

It is to be understood that the detailed description is not to be considered restrictive of the invention. For example, any plastic may be used that has the desired characteristics. It should be emphasized that while the invention may perform the functions of a toothpick it also will function to massage the gums, as illustrated in FIG. 4 in which the back of blade 14 may engage the gums, and the rounded surface of the pick in will massage the gums, even where slightly roughened since the plastic will not cut or injure the gums.
