Why does orange juice taste so terrible if you drink it right after you've brushed your teeth?

One of the ingredients in toothpaste... One of the ingredients in toothpaste, namely sodium laurel sulfate, temporarily blocks the sweet (and salty) receptors in your taste buds. The sour and bitter receptors function fine, so that is all you taste in the orange juice, which does have some sour and bitter components. Sodium laurel sulfate is a detergent, also found in shampoo, that creates the foam you get when you brush your teeth.

Supposedly it helps drive oxygen into the crevices in your teeth. The bacteria that make up plaque are anaerobic, so oxygen retards their growth or even kills them. But some claim that it has no effect other than to make you feel you are cleaning your teeth (foam equates with cleaning, in people's minds.) You can try an experiment.

Take a sip of salty water, brush your teeth, and then taste again. (use a liquid so it spreads over your tongue, and the fact that the different taste buds are grouped into specific areas on your tongue doesn't confuse the results.) The next day, try the same with sugar water. Then with water with lemon juice.

I can't think of a safe, easily available bitter taste, but maybe you can leave out that piece of it. Sources: abc.net.au/goldcoast/stories/s1669605.htm .

Drinking orange juice just after you have brushed your teeth is one of the most excruciatingly disgusting things known t It's because of a certain ingredient in toothpaste called sodium laurel sulfate. It actually blocks sweet sensors. All the other taste bud cells in your mouth are firing away nicely, but the receptors which pick up the sweet sensors are not working anymore.

Not only does it block the sweet sensors, it enhances the sour and bitter, so you get this massive influx of sour and bitter taste coming through the mouth.

Saccharin Most tooth paste contains artificial sweeteners (usually saccharin). These produce an overly sweet taste. If you have the natural sugar in orange juice, while your tongue is still recoving for this blast of super sweet, it will register the less sweet, natural sugars (fructose) as bitter..

2 ThoughtMonkey, regarding your answer "Saccharin":I don't believe your answer is correct, but you (or I) can test it by eating a good amount of saccharin, then taking a drink of orange juice. We could also test it by trying some toothpastes that don't have saccharin, but I imagine they are expensive (i.e. , "all natural") or don't taste good, and that is a greater sacrifice than I am willing to make, even if it is for science.

Also, those toothpastes might not have sodium lauryl sulfate either, so we wouldn't know which chemical is the one that causes the taste effect.

Whats the difference between orange juice and sports drink.

What happens if you drink juice a mouse has been in.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
