Designed for mouth packing and moisture control during dental procedures, these rolls are single-use, 100% pure cotton. Lint-free and highly absorbent. Mouth packing, also known as throat packing, is the process of filling a mouth with absorbent material so as to protect the patient’s airway from potentially aspirating saliva, blood, or other fluids. Made from 100% absorbent cotton, this is a great alternative to other, less absorbent mouth packs.
