An oral carrier strip for the delivery of an oral care composition to the oral cavity of a human or animal subject is provided. The strip includes a first portion adapted to contact a front facing side of a plurality of teeth. A second portion is provided to be folded around the teeth so as to contact a back facing side of the teeth. The first portion has a first perimeter patterned to substantially match a shape of an outer gingival tissue, and the second portion has a second perimeter opposite the first perimeter and patterned to match a shape of an inner gingival tissue. The second perimeter defines an aperture disposed in the second portion having a rounded notch positioned in a center portion of the strip, configured to prevent the strip from tearing when folded around the teeth.
