I'm changing my vote to nea. Yes, it does work...temporarily. My coating started returning in 2 days despite cleaning the tongue twice a day. Leaving baking soda on the tongue for a few minutes then brushing also removes the coating and without the dangers of salt. Salt can burn and even permenantly damage the tongue. I'm sure you can safely use baking soda several times a week without a problem

I was so excited to try the salt remedy that everyone here mentioned to cure by white tongue, but I'm afraid it did not work...at all. I did the rinsing with sea salt, then sprinkled salt on my tongue and let it sit there for five minutes, then three times brushed my tongue with a sea salt/water paste, and it did nothing to remove the whiteness on my tongue and make it any pinker.

Didn't work for me. Tried brushing with salt and rinsing gargling with salt water. No effect.

White Tongue Remedies: I just wanted you to know I tried the salt water thing. The white on my tongue did not come off. I am going to try the listerine next and I will let you know if that does not work.
P.S. Brushing your tongue is usually not a good idea. You should check with your doctor first to find out if it is serious or not. Brushing your tongue with a serious tongue condition can pretty much make it worse or ruin your tongue for life.
