Obstruction of salivary flow caused by denture overextension

An unusual case of submandibular gland salivary flow obstruction created by an overextended denture has been described. The many potential causes of submandibular gland swelling are listed. Clinically, the opening of both Wharton's ducts appeared more anterior than usual. This anatomic fact, combined with the overextended lingual flange of the denture, combined to produce the phenomenon of bilateral submandibular gland swelling.
