You may have a bad taste in your mouth due to something that you’ve eaten, dental problems, or other health conditions, including an infection or neurological issues.
Everybody has a bad taste in their mouth occasionally. It usually goes away after brushing your teeth or rinsing out your mouth.
However, in some cases the bad taste sticks around due to an underlying cause. Regardless of what’s causing it, having a bad taste in your mouth can ruin your appetite, possibly leading to nutritional deficiencies and other problems.
If the bad taste doesn’t go away after a day or two, work with your doctor to figure out what’s causing it. Also be sure to tell them about any changes in your appetite or sense of smell.
