The cheek and lip retractor for dentistry comprises respective cheek portions (7, 8) and lip portions (1, 2) for the upper and lower lip, said lip portions comprising a lip shield (3, 4) and mucosa pads (5, 6) which are separate and spaced apart from said lip shield, said cheek portions and lip portions being connected to each other by flexible connecting elements (9-12), and said connecting elements being disposed between said lip shield and said mucosa pad. Such a retractor allows a largely free treatment of the tooth portions to be treated and provides a comfortable fit for the patient.
