Acid reflux occurs when undigested food, bile and stomach acids flow backwards out of the stomach and into the esophagus, usually as a result of a weak or malfunctioning lower esophageal sphincter, according to Healthline. This not only results in bad breath but a sour or bitter taste in the mouth. Treating the acid reflux also helps eliminate the bad breath it causes. Treating acid reflux requires eliminating certain foods from the diet, such as coffee, alcohol, citrus fruits, tomato products and garlic.
