About 3 weeks ago I suddenly lost taste of whatever I ate for 2 days. After that when I checked my mouth I noticed there were white lines along the walls of my cheeks. Also I felt a slight swelling on the inside of the cheeks. Doctors gave me antibiotics, mouthwash and tablets. I changed 2 doctors one a general physician and another an ENT doctor in an attempt to cure my problem. The white lines along my cheeks are still there. When I run my tongue on the inside of my mouth it feels as if the inside is oily. I got fed up with the medicines the doctors gave me although I had taken the full prescribed dosage. I found I was still having this problem so I started applying dabur red toothpaste to the inside walls of my mouth and rinsed my mouth after keeping the toothpaste in it for about 10 minutes. I am still doing this but there doesn't seem to be any improvement.
