Just like many other problems the metallic taste could be due to many problems. Some are due to the medication you could be taking. Another reason could be due to dental problems. If you don't drink enough water it could affect your taste.
A metallic taste in the mouth is a fairly common problem - and usually not serious. Although you don't have actual taste buds that detect metals, the perception of the taste is described as "metallic."
A metallic taste can be due to many factors. But the most common causes of a metallic taste are:
Medications such as some antibiotics, prenatal vitamins and antidepressants, as well as drugs used to treat high blood pressure, rheumatoid arthritis and kidney stones
Oral problems, including oral infections such as gingivitis or periodontitis, tooth infections, and poor oral hygiene
Sometimes the cause of a metallic taste can't be determined. In many cases, the problem goes away on its own after several months or longer. Proper oral hygiene can help, including regularly brushing your teeth and brushing and scraping your tongue. Done properly, dental restorations - such as fillings and inlays - are rarely the cause a metallic taste.
It means you can taste metal :P
What causes peppery mouth
A metallic taste in the mouth is a common complaint and can be due to a variety of causes - from medication you may be taking to dental problems. In the absence of other symptoms, it is unlikely that a metallic taste in your mouth indicates serious disease. But if you haven't had a thorough general checkup recently, I would suggest seeing your doctor to rule out any undiagnosed health problems.

It's possible that I'm pregnant. I haven't had many other symptoms except the past couple weeks off and on I get the taste of metal in my mouth. My friend told me it was a symptom but I've never heard that. I am pregnant and I have noticed a weird taste in my mouth. I get the metallic taste in my mouth right before my period, so maybe it is hormonal. Yes! If you do an internet search for "pregnancy symptoms" you will find that having a metal taste in mouth is among the top symptoms. When I have pregnant of my first baby, the first thing I notice was that metal taste in my mouth which I nerver had before. Now, we are trying for a second child (we should know for sure this week-end), I got the same metal taste in my mouth for the past 3 days. No...I got a metallic taste in my mouth and have had it for the past 4 days. Ive been on the pill for years and was freaking out that I was pregnant, I felt like I had other symptoms too. I took 4 urine tests and a blood test and all of them were negative. Turns out I was dehydrated.
Sour metal taste in your mouth and lots of heartburn.
Metal taste in your mouth could be caused by a few factors: either you are suffering a gum disease, or are undertaking medication which causes this effect or that you are lacking enough iron in your body. If it persist for more than a day, its time to see your dentist and/or your general practitioner respectively so as to get the right cause of it.
