Dental devices and related methods

A handheld dental device, comprising:

• a first handle structure comprising a first rotational section;
• a second handle structure comprising a second rotational section that comprises at least one orifice disposed through at least a portion of the second rotational section and one or more second projection elements that extend from at least one surface of the second rotational section;
• a post element disposed through the orifice of the second rotational section of the second handle structure, wherein at least a first portion of the post element is operably connected to the first rotational section of the first handle structure such that the post element and the first handle structure are substantially fixedly positioned and substantially non-rotatable relative to one another;
• and
• a rotational structure comprising one or more first projection elements that extend from at least one surface of the rotational structure, wherein at least a second portion of the post element is operably connected to the rotational structure such that the post element, the rotational structure, and the first handle structure are substantially fixedly positioned and substantially non-rotatable relative to one another,
• wherein at least a segment of the second rotational section of the second handle structure is disposed between at least a segment of the first rotational section of the first handle structure and at least a segment of the rotational structure such that the second handle structure is at least partially rotatable relative to the post element, the rotational structure, and the first handle structure,
• wherein the first and second projection elements together form at least one projection element pair, wherein at least a portion of the projection element pair is dimensioned to fit at least partially within an opening disposed in or between one or more natural and/or prosthetic teeth in a mouth of a given subject when the projection element pair is in a closed position and when the projection element pair is positioned at least partially in the opening disposed in or between the one or more natural and/or prosthetic teeth in the mouth of the given subject,
• wherein when the first and second handle structures are moved toward one another, the first and second projection elements of the projection element pair move away from one another in directions that are substantially perpendicular to a rotational axis of the first and second handle structures such that at least segments of the projection element pair contact the one or more natural and/or prosthetic teeth in the mouth of the given subject when the projection element pair is positioned at least partially in the opening disposed in or between the one or more natural and/or prosthetic teeth in the mouth of the given subject, and
• wherein at least a portion of the handheld dental device is dimensioned to at least partially fit within the mouth of the given subject.
