A sealed envelope or enclosure, shaped to fit a portion of the internal anatomy of the human mouth at a surgical site, said enclosure containing a non-toxic liquid or gel material capable of freezing to a semi-solid or solid state. The envelope may also contain a binder such as a sponge material or gauze impregnated with the liquid or gel material. The enclosure is placed in the mouth, to provide both pressure and cold, to reduce bleeding, swelling and pain after oral surgery or trauma.
