It is an unusual taste or change in taste that won’t go away. It can be described as inadequate, metallic, salty or foul.
Your taste buds are found on your tongue and on the roof of your mouth. These cells collect information related to taste and send it to the brain.
Some people with dysgeusia also develop an altered sense of smell. About 75% of flavor and taste sensations come from nerve cells involved with smell. Both taste and smell cells work together to produce a sense of taste.
Our taste cells can identify four main qualities: sour, bitter, salty and sweet. More subtle aspects of flavor come from your sense of smell. Try this experiment. Take a sip of coffee or eat an orange slice while you hold your nose. It will be difficult to taste the flavor of the food or drink.
Dysgeusia is relatively uncommon. It can have numerous causes. Fortunately, many of the causes are temporary. For example, several infections can cause mild dysgeusia. They include the common cold, flu, sore throat, and nasal or sinus infections. Causes of dysgeusia are rarely life-threatening, but the disorder may affect your quality of life.
Other causes include:
- Smoking (especially pipe smoking)
- Gingivitis (inflammation of the gums)
- Periodontal disease (advanced gum disease)
- A dental abscess.
- Oral yeast infection.
- Certain medicines, including lithium, antibiotics, ACE inhibitors, and many cancer drugs.
- Dry mouth (xerostomia), which can be caused by many medicines
- Vitamin or mineral deficiency
- A brain tumor or trauma to the head
