@jobaab I know exactly how you are feeling. I've been dealing with either a very salty taste or a sour/bitter taste depending on the day. Have you been diagnosed with Sjorgren's Disease? I have it and it decreases your saliva but all the remedies that normally help have not helped me. I've used rinses, sprays, special toothpaste, drinking lots of water, avoiding certain foods and even trying to prescription medications that increase saliva. Yesterday I actually made popcorn from kernels and did not put a drop of salt on them and it tasted as if I had salted it. The doctors are baffled. Some think it's dry mouth that just doesn't respond to the normal treatments and another one thinks it's neurological. Chewing Trident gum which has xylitol masks the taste but I get tired of chewing gum all day. I recently started 60mg of duloxetine (Cymbalta) once a day. It has taken the edge off the saltiness but it has by no means cured anything. Have to been to the dentist to get their opinion?
