This invention is directed generally to dental equipment. More particularly, this invention relates to dental extraction tools. Specifically, the present invention is a pair of dental pliers that may be used by a parent or care-giver to extract a non-permanent tooth of a child in a setting outside of a dental office. The dental pliers include flexible handles that limit the force that is able to be applied to a tooth when captured in a cupped region of the pliers jaws.
There are many types of dental extracting forceps that are known in the art for use when extracting permanent adult teeth. These dental forceps, which are also known as dental pliers, are typically machined from stainless steel. They include a pair of handles that are pivotally engaged with each other. Each handle has a jaw at one end and the jaws may be moved toward or away from each other by manipulating the handles. The jaws may be differently configured from one pair of dental forceps to another. Some types of dental forceps have straight jaws, others have angled jaws and yet others have a combination of straight and angled jaws. Typically, the jaws are configured such that there is a slightly cupped shape proximate and end of the jaws. The cupped region is provided to engage a tooth shape. Dental forceps are very strong and must be thoroughly cleaned and sterilized in an autoclave after each use. An autoclave uses high heat and steam to sterilize and clean the instrument.
The force needed to grip dental forceps and extract a permanent adult tooth can be surprisingly high for the dentist. An extraction procedure for an adult molar with two or three roots may often begin with a twisting rotational movement to try to loosen the roots. The rotational motion may be followed by a firm pulling motion. Care must be taken so the roots do not break off the tooth and remain in the jaw where they may subsequently cause infection. Often a dentist of slight build may prepare the patient and then summon a larger or stronger associate to perform the pulling motion.
Non-permanent teeth, also known as baby teeth, typically fall out by themselves when the child or young person is around six to twelve years old. Non-permanent teeth typically have no significant roots and are attached to soft tissue. They can therefore fall out of the child's mouth while the child is sleeping, spitting out (during brushing of their teeth, for instance), or they may fall out during eating and may be accidentally ingested. A non-permanent tooth may be become “wiggly” and take several days to become sufficiently disengaged from the soft tissue. The tooth may tend to rotate, get stuck on other teeth and generally become a nuisance and a stressor for the young child. Often parents will try to assist the process by pulling the loose tooth with their fingers as best they can. In other instances, they will try “home remedies” such as tying a piece of string around the tooth at one end and a door-knob at the other in order to remove the loose tooth from the child's mouth. All of these attempts at tooth removal may be somewhat distressing to the child and to the parent.
Once a loose tooth is removed and, in order to make this whole process less stressful and slightly rewarding for the child, the tooth will be put under the child's pillow or in some specially designated spot or receptacle and the mythical “Tooth Fairy” will come and replace the tooth with a coin or other reward while the child sleeps.
There remains a need in the art for a better way to help a parent remove a loose non-permanent tooth from a child's mouth. The dental pliers disclosed herein provide this assistance. The dental pliers include a left leg and a right leg that are pivotally engaged with each other. Each of the left and right legs has a handle and a jaw. The handles are fabricated from a flexible material that flexes when too much force is applied thereto to move the jaws to a closed position. The flexible handles thus limit the amount of force that may be applied to extract a tooth. The jaws include jaw tips that taper inwardly toward each other and angle downwardly from the handles. The jaw tips include angled interior surfaces that define a cupped region shaped to be able to contact a base of the tooth during the extraction process. The pliers are able to be cleaned and sanitized in a dishwasher after use.
In one aspect, the present disclosure may provide a pair of dental extraction pliers comprising a left leg having a handle and a jaw; a right leg having a handle and a jaw; wherein the handles are fabricated from a flexible material; a pivot pin engages the left and right legs to each other; wherein the handles are movable towards each other or away from each other; and when the handles are moved towards each other, the jaws are moved toward each other; and the flexible material of the handles limits a force that is applied by the jaws.
In other aspects, the present disclosure may provide a pair of dental pliers where the jaws include jaw tips that angle forwardly and downwardly relative to a remaining region of the jaws and the handles. The jaw tips angle downwardly at an angle of from about 110 degrees up to about 140 degrees and preferably is about 125 degrees relative to the remaining region of the jaws and the handles. The jaw tips taper inwardly towards each other when the pair of dental pliers is viewed from above or when the pair of dental pliers is viewed from a front end. The jaw tips have interior surfaces that are oriented at an angle of from about 10 degrees up to about 40 degrees and preferably about 25 degrees relative to an adjacent region of the jaw; the interior surfaces are opposed when the handles are moved to the closed position; and when the handles are in the closed position the opposed interior surfaces form a cupped region adapted to receive a tooth therein.
In other aspects, the present disclosure may provide a pair of dental pliers that further comprise a spring extending between the handles. A first spring housing extends outwardly from an interior surface of the handle on the left leg and a second spring housing extends outwardly from an interior surface of the handle on the right leg. A first end of the spring is seated in the first spring housing and a second end of the spring is seated in the second spring housing. The first spring housing abuts the second spring housing when the handles are moved to the closed position. The spring biases the handles into the open position.
In other aspects, the present disclosure may provide a pair of dental pliers that includes handles made of a flexible material such as an injection molded plastic that is overmolded with rubber. The jaw tips of the jaws are fabricated from metal such as die-cast aluminum. The pair of dental pliers is fabricated from dishwasher-safe materials.
In another aspect, the present disclosure may provide a method using a pair of dental pliers comprising providing a pair of dental pliers having pivotable left and right legs each having a handle and a jaw; wherein the handles are fabricated from a flexible material; positioning jaw tips of the jaws in the child's mouth on either side of a non-permanent tooth that is loosely retained in the soft tissue of the child's gum; positioning angled interior surface on the jaw tips adjacent a base of the non-permanent tooth; applying a force to the handles; moving the jaws toward each other; capturing the non-permanent tooth between the angled interior surfaces; limiting an amount of force able to be applied to the non-permanent tooth by the jaws; applying a pulling motion to the captured non-permanent tooth; and extracting the non-permanent tooth from the soft tissue.
In another aspect, the present disclosure may provide a method wherein the step of limiting comprises flexing the flexible material of the left leg handle and the right leg handle inwardly toward each other once a maximum threshold force is applied to the left and right leg's handles. Alternatively, the step of limiting may comprise abutting a first spring housing provided on the handle of a left leg of the dental pliers against a second spring housing provided on the handle of a right leg of the dental pliers; and stopping motion of the jaw of the left leg and the jaw of the right leg towards each other.
In yet another aspect, the present disclosure may provide a method that includes placing the dental pliers into a dishwasher after extraction of the non-permanent tooth; and cleaning and sanitizing the dental pliers in the dishwasher. The method may further comprise a use of the dental pliers described above by a parent or a care-giver of the child in a setting outside of a dental office.
A sample embodiment of the disclosure is set forth in the following description, is shown in the drawings and is particularly and distinctly pointed out and set forth in the appended claims. The accompanying drawings, which are fully incorporated herein and constitute a part of the specification, illustrate various examples, methods, and other example embodiments of various aspects of the disclosure. It will be appreciated that the illustrated element boundaries (e.g., boxes, groups of boxes, or other shapes) in the figures represent one example of the boundaries. One of ordinary skill in the art will appreciate that in some examples one element may be designed as multiple elements or that multiple elements may be designed as one element. In some examples, an element shown as an internal component of another element may be implemented as an external component and vice versa. Furthermore, elements may not be drawn to scale.
Similar numbers refer to similar parts throughout the drawings.

Since a parent or care-giver should only be extracting an already loose, wiggly tooth (“T”—see
Pliers 10 comprise a left leg 12, a right leg 14, and a pivot pin 16 that engages the left leg 12 and right leg 14 to each other. A spring 18 (
Handle 12c, neck section 12f and base 12d may be molded as a single, integrally formed, unitary component or may be fabricated as separate sections that are secured together. Handle 12c, neck section 12f and base 12d may be fabricated from a relatively inexpensive injection molded plastic such as polypropylene. This plastic may be brightly colored to give the pliers 10 a more playful and child-friendly appearance. Handle 12c may be provided with a rubber overmold to assist a parent or care-giver to grip pliers 10. Neck section 12f may be molded to be generally narrower and thinner than either handle 12c or base 12d and may include a collar 12f′ having a front surface and a back surface. A hole 12g (

Neck sections 12f, 14f are configured to be complementary in the sense that they are shaped to be positioned adjacent each other and cooperate with pivot pin 16 to allow jaw tips 12d, 14d to be moved toward and away from each other. When left leg 12 and right leg 14 are to be engaged with each other the neck sections 12f, 14f are overlapped with each other. The neck sections 12f, 14f may be configured so that they are only able to overlap in one orientation so that jaw tips 12e and 14e will be correctly oriented in pliers 10. When neck sections 12f, 14f are overlapped, holes 12g, 14g are brought into alignment with each other.
Pivot pin 16 may be fabricated from a plastic material and may comprise complementary first section 16a (
Jaw tips 12e and 14e may be fabricated as separate components that are then engaged with bases 12d and 14d, respectively. Jaw tips 12e, 14e may be die-cast aluminum components that are insert-molded with the associated bases 12d, 14d. The polypropylene used for the rest of the legs 12, 14 may be very soft and therefore a bit flexible. Applying sufficient force to extract a tooth would therefore be quite difficult. The aluminum die cast jaw tips 12e, 14e are sufficiently solid enough to accurately engage a tooth without slipping and are capable of applying sufficient force to grip and extract a loose tooth.
It should be noted that the materials used to fabricate pliers 10 are only a fraction of the cost of a machined, stainless steel pair of dental forceps such as those used by dentists. The materials used to fabricate pliers 10 are light-weight and non-corrosive. Because the handles 12c, 14c are made of a flexible material, they tend to limit the amount of force that can be applied by pliers 10 and therefore tend to make the pliers 10 safer and easier to use. The parent or care-giver, following instructions provided on an instruction sheet provided with pliers 10 will be able to extract loose non-permanent teeth relatively easily.
Head 22 is comprised of a first section 22b and a second section 22c. The end 22a is provided on first section 22b. When jaw tip 14e (

Dental pliers 10 may be used by a parent or care-giver of a young child in a non-dental setting (i.e., in a location such as the young child's home) in the following manner. The parent or care-giver will position jaw tips 12e, 14e of jaws 12d, 14d in the child's mouth on either side of a non-permanent tooth “T” that is loosely retained in soft tissue “ST” (
The maximum threshold amount of force that may be applied to handle 12c, 14c may also limited by abutting contact of first spring housing 12h provided on handle 12c and second spring housing 14h on handle 14c. When first spring housing 12h and second spring housing 14h contact each other, further inward motion of the upper ends of handles 12c, 14c (proximate neck regions 12f, 14f) is stopped and thereby movement of jaw tips 12e, 14e towards each other is stopped.
Once tooth “T” has been extracted, the parent or care-giver may place dental pliers 10 into a dishwasher to clean and sanitize dental pliers 10 in the dishwasher.
