Hello and Welcome to HCM,
Thanks for writing to us.
A metal-like taste in the mouth often goes away on its own within a couple of days, without any medical intervention. But persistent metallic taste
can be associated with certain medical conditions. So, it is important to know the factors that can bring about a change in the taste.
Brushing your teeth twice a day with a mint-flavored toothpaste can help a lot, as the lack of oral hygiene
is one of the most common causes of an altered sense of taste. Along with brushing, do not forget to floss and use a tongue scrapper to clean your tongue.
Drink plenty of water throughout the day to eliminate that bad taste in your mouth.
Chewing gum is another useful remedy for metallic taste.
Hope this helps you.
Wishing you good health...
