Bitter or Sour Taste
In some cases, a person who has heartburn may sometimes experience a bitter or sour taste inside his or her mouth. This happens mainly because the condition causes your stomach contents to reflux up to the esophagus and might reach the back of your throat, thus resulting in an unpleasant taste. Due to the acid’s nature, there will be many other gaseous issues. People with this problem can use dental or mouth rinses to remove the taste. Also, you can suck on peppermints to take out the taste and settle your stomach. [7]
