Taste in the mouth

Taste in the mouth is a sensation that can vary from person to person. It can range from a salty, sweet, or sour taste to a metallic or bitter taste. It can also be a combination of tastes. The taste can develop gradually or suddenly, and it can last for a few minutes or for a longer period of time.
