Gingival bleeding, gastrointestinal disorders, etc. Gingivitis and periodontitis—both common conditions—can cause a metallic or bloody taste in the mouth. In cases of gingivitis or periodontitis, gingival tissues typically become red, swollen, fragile, and prone to bleeding, often accompanied by a bloody taste; professional dental cleaning (scaling and root planing) at a dental clinic is recommended. Alternatively, the symptom may stem from gastrointestinal disorders—for instance, esophageal or gastric bleeding—which can reflux into the oral cavity.
