      The causes for metallic taste in mouth can range from medicines to many systemic conditions. Medications, especially vitamin B complex, antibiotics, antiamoebics, are known to produce metallic taste in mouth. Poor dental hygiene is another major concern. If you have not done a general body health check up, consult your doctor to rule out any underlying undiagnosed health problem. Meanwhile drink enough water and fluids. Brush your teeth at least two times in a day. Clean your tongue with a tongue scrapper. Eating certain foods helps to reduce metallic taste in mouth such as fruit smoothies, orange and lime juice, salads, tomato soup, frozen yogurt etc. Sucking peppermint candies and chewing gum helps to reduce metallic taste in mouth.
