Hi
@Smitten73,
Could be an upper respiratory infection, middle ear or dental problems.
What causes taste disorders?
Some people are born with taste disorders, but most develop them after an injury or illness. Among the causes of taste problems are:
- Upper respiratory and middle ear infections
- Radiation therapy for cancers of the head and neck
- Exposure to certain chemicals, such as insecticides and some medications, including some common antibiotics and antihistamines
- Head injury
- Some surgeries to the ear, nose, and throat (such as middle ear surgery) or extraction of the third molar (wisdom tooth)
- Poor oral hygiene and dental problems.\
