1. An oropharyngeal dam for facilitating a safe and efficient dental treatment, the oropharyngeal dam comprising:
a pair of cheek retractors located between a set of lip retractors, wherein each of the pair of cheek retractors comprises:
an upper retractor component configured to adapt to soft tissues of a buccal vestibule of an upper back teeth;
a lower retractor component configured to adapt to a buccal vestibule of a lower back teeth; and
a cheek retracting sheet extending between the upper retractor component and the lower retractor component, wherein the upper retractor component, the lower retractor component, the cheek retracting sheet, and the set of lip retractors are collectively configured to retract cheeks of a patient;
a tongue protector located between the pair of cheek retractors, wherein the tongue protector comprises:
an upper protector component configured to adapt to a palate of mouth;
a lower protector component configured to adapt to soft tissues of a lower lingual vestibule; and
a tongue protecting sheet extending between the upper protector component and the lower protector component, wherein the upper protector component, the lower protector component and the tongue protecting sheet are collectively configured to shield and retract a tongue of the patient;
the set of lip retractors adjoined with edges of the pair of cheek retractors, wherein the set of lip retractors are configured to aid lip retraction when pulled outside the mouth and on closing the mouth; and
a throat shield located between the upper protector component and the lower protector component, wherein the throat shield has a curved structure, and wherein the throat shield is a double sheet barrier comprising:
an outer sheet, wherein the outer sheet facing outwards towards the mouth comprises a set of perforations, wherein the set of perforations collects aerosols formed during the dental procedure and evacuates the collected aerosols via one or more suction vents, and wherein the set of perforations are connected to the one or more suction vents present on the lower protector component;
an inner sheet, wherein the inner sheet facing towards throat of the patient forms a mechanical barrier to prevent bioaerosol transmission and aspiration of materials used during a dental procedure; and
