Dysgeusia

Taste and its role in the enjoyment of food is something that many of us take for granted. However, a taste disorder can have a negative effect on our quality of life and nutrition. It may also indicate an underlying problem.

Tongue dysgeusia is a taste disorder that manifests as a lingering, unpleasant sensation in the mouth. People who experience a taste disturbance often report having a frequent foul, rancid, metallic, or salty taste perception. The condition has been attributed to physiologic changes in the body, certain diseases, vitamin deficiencies, prescription medications and cancer treatment.

Here are a few causes of this taste disorder that may help your dentist or physician identify the root of the problem and hopefully get you back to enjoying food.
