Vitamin K, a fat soluble vitamin, is an essential factor for the activation and synthesis of coagulation factors II, VII, IX, X and protein C and S. Vitamin K deficiency can easily develop in patients having chronic debilitating mouth disease such as oral submucous fibrosis (OSMF) due to poor nutritious food intake. We present a case of a 45 years old male patient having grade II OSMF reporting with intermittent bleeding and swollen gingiva with extravasation of blood in gingiva and floor of mouth secondary to local trauma. Patient’s prothrombin time, activated partial prothrombin time and platelets were increased leading to inadequate activity of coagulant factors such as factors resulting in intermittent spontaneous bleeding and extravasation of blood in gingiva and floor of mouth. Patient was treated with injectable Vit K. There was complete resolution of extravasated bleed and edematous gingiva with stoppage of intermittent spontaneous bleeding. Periodontal surgery took care of localised periodontits.
