Heartburn, or gastric reflux, is a common cause of bad taste. Stomach acid regurgitated into the mouth produces a bad taste described as an acid or metallic taste. An infection of one of the major salivary glands is also a common cause of bad taste. Similarly, poor dental hygiene causes bacterial growth in the mouth that could result in a bad taste. Another possibility is a viral infection that may damage the tongue’s sensory cells and result in changes to the sense of taste. Other mouth or tongue disorders, including mouth ulcers, are a possible cause, as well.
Bad taste may also result from radiation therapy and medicines, such as antibiotics and angiotensin-converting enzyme (ACE) inhibitors. Taste problems may take months or even years to resolve. Some changes may be permanent, especially if the mouth is a target of direct radiation therapy.
