1. An isolation mouthpiece for use with a suction system in a dental procedure, the isolation mouthpiece comprising:
a main body portion having a first end and a second end, the main body portion including:
a first wall having a first shape defined by a first edge and a second edge extending from the first end of the main body portion towards the second end of the main body portion,
a second wall having a second shape defined by third edge and a fourth edge extending from the first end of the main body portion towards the second end of the main body portion, the second wall including a first plurality of perforations extending along a portion of the third edge, and a second plurality of perforations extending along a portion of the fourth edge, wherein a plurality of crests of a wave-like structure is formed on an interior surface of the second wall to provide contact points with the first wall, and a plurality of troughs of the wave-like structure provides gaps between adjacent ones of the plurality of crests for allowing the suctioning of fluid through the plurality of troughs; and wherein the first wall and the second wall are shaped such that the first edge of the first wall corresponds in shape to the third edge of the second wall and the second edge of the first wall corresponds in shape to the fourth edge of the second wall; and wherein the first shape of the first wall corresponds to the second shape of the second wall, and
a third wall connecting the first wall and the second wall such that the first wall is spaced from the second wall, wherein a portion of the first wall has a first width adjacent to the first end of the main body portion and a second width adjacent to the second end of the main body portion, wherein a portion of the second wall has a third width adjacent to the first end of the main body portion and a fourth width adjacent to the second end of the main body portion, wherein the first width is greater than the second width, and wherein the third width is greater than the fourth width;
a suction connector portion extending from the first end of the main body portion, the suction connector portion including:
a tubular conduit including an opening extending through the conduit and in fluid communication with the plurality of troughs of the wave-like structure, the opening being configured to receive a vacuum portion of the suction system therein, the tubular conduit further including a cutout configured to engage a protrusion on the suction system to aid in coupling the isolation mouthpiece to the suction system, and
a mouth prop including a first side and a second side that are inwardly tapered from a top surface of the mouth prop towards a bottom surface of the mouth prop, the first side and the second side each including a plurality of ridges; and
a cheek retractor portion having a first cheek-retractor end coupled to the second end of the main body portion and a second cheek-retractor end, the first cheek-retractor end and the second cheek-retractor end each having rounded edges.
