Veda #70 : Toothbrush Vs OJ

Day 70
"Why does orange juice taste odd after toothbrushing?"


For you who enjoying a glass of OJ in the morning, please consider this. If you ever feel odd drinking OJ in the morning after you've brushed your teeth, now you can see the explanation. Oh yeah, for you who enjoyed the sweet tea in the morning, could feel the same.

To work out what’s going on we need to know about toothpaste, orange juice and how your taste buds work. Your tongue has four areas that are sensitive to sweet, sour, bitter and salt. The sweet part is right at the front of your tongue.

Toothpaste usually creates a lot of foam in your mouth and this can temporarily affect your sweet taste buds. Look at the label on your toothpaste to see if it has an ingredient called Sodium Lauryl Sulphate (SLS). This is a detergent and it’s found in 99% of all toothpastes. It doesn’t really do anything useful, but just creates a lot of foam that makes you feel like your teeth are getting nice and clean.

Because your sweet sensors are not working so well you mainly taste the bitter taste of the citric acid found in orange juice. The sugar sweet taste is not there.
The same also happen on the other sweet drink.
