Yes, I also gargle baking soda and water and no bad breath or bad taste in my mouth. Apparently it kills bacteria in your mouth but I am no dentist.
I have been swishing sodium bicarbonate for a few weeks now and the most noticeable effect is that my wife can't believe that my "bad breath" has almost gone.
For almost two years, I have been self-conscious about my bad breath. I always kept myself at least a meter away from my friends, not to mention about girls. I visited several dentists, but none couldn't tell any concrete solution. Recently, a dentist told me to wash my mouth, especially back of my tongue with a BAKING SODA before going to sleep and to take a pill, called Flunol. I washed my mouth with baking soda, but did not take the pill, as it was expensive. To my great surprise, it was enough to get rid of the bad breath. Within ten days, it is almost gone. I still can't believe it and just before writing this message, I checked it, putting my finger in the back of my tongue. it's gone. I know there are many people with the same problem and i want to say those people not to spend much money on those expensive pills and liquids. Instead, look for a cheap, home remedy. And if you really want to get rid of your bad breath and believe in that, you will do it. If anyone of you know how to get rid of black spots, natural moles on the face, please share it with me. Thanks.
