no. i had the taste before the CS. and for me the taste never goes away. which is strange and frustrating. after the polyp surgery i lost ALL sense of smell and taste. and that was about 5 years ago, maybe. i'm not at 100% back. now about the acid reflux. i disagree. i have gerd. and believe me. there is nothing metallic tasting about it. it's stomach acid. and it BURNS. question. do you have any cavity repair work done? also before you see the dentist. thoroughly check your tongue and teeth, gums. roof of mouth, under your tongue. you can do this with a flashlight and your bathroom mirror. look for anything that don't look right. and don't forget the insides of your cheeks. looking for anything not normal. cause if you see something you can let the dentist know what you found. remember, if it's small let him/her know. and also as i say. IF you don't get the results you agree with, find a different doctor. because this is NOT normal. it's YOUR right. good luck, d
