Why does orange juice taste like shit after we brush our teeth?


| 2 Comments

Waking up for my 8am every Monday, Wednesday, and Friday is never an easy task, in fact just in order to begin thinking straight I need to get a hot shower, brush my teeth, and drink a tall glass of orange juice. From an early age I've always enjoyed a glass of orange juice in the morning, but one thing I've never enjoyed is the awful taste of the drink after brushing my teeth. So why the hell does orange juice taste like shit after we brush our teeth? Well I'm not sure and this is why I pose this question, so lets take a deeper look into the topic, and hopefully come up with an answer for this paradox that has troubled man since the beginning of time!

According to HowStuffWorks scientists don't fully understand how taste works, however they do have a pretty good idea and hold a general consensus as to what causes the horrific taste when OJ & toothpaste are combined. Many of us would consider orange juice's sweet citrus taste to be very enjoyable when drank alone, just as we enjoy the minty fresh taste of a well brushed mouth, however the combination of the two is disastrous. The most commonly accepted theory as to what taste is according to another article from HowStuffWorks, is "a chemical sense perceived by specialized receptor cells that make up taste buds". These taste buds or taste receptors are separated into five sections on the tongue that are best at picking up that specific taste; the categories are as follows sweet, salty, sour, bitter, and umami a Japanese word meaning delicious savory taste. Scientists currently believe that taste sort of works like a puzzle, where molecules of a certain shape will interact with receptors that are shaped to accept them, however these receptors are easily manipulated which is why scientists believe the combination of orange juice and toothpaste is not a good one.

So who is responsible for the foul taste, the OJ or the toothpaste? Well many scientists believe that the foaming agent found in toothpaste known as sodium lauryl sulfate (SLS) is mainly responsible for the offense. SLS destroys phospholipids, which are fatty compounds that serve as inhibitors on the bitter receptors, on top of this SLS also dampens our sweet receptors suppressing orange juice's sweet citrus taste we've all learned to love. So by increasing your tongue's ability to detect bitterness and decreasing your tongue's ability to taste sweetness, it is no wonder why orange juice tastes so awful after brushing your teeth. According to Science Made Simple dentists believe that SLS is responsible for giving people mouth ulcers as well.

The bottom line is that orange juice tastes bad directly after brushing your teeth because of the foaming agent found in 99% of all toothpastes known as SLS. In order to avoid this problem you could stop brushing your teeth or stop drinking orange juice all together, which I don't recommend doing either of the two. Instead it would be wise to eat a light snack before drinking your OJ or simply brush your teeth AFTER drinking your orange juice. If you follow one of these simple tips you will no longer gag first thing in the morning from the repulsive taste of orange juice after brushing your teeth.

I hate OJ! I hate OJ even more when it is followed by toothpaste rather than mixed with champagne. But have you ever tried to brush your teeth with something other than toothpaste? I was told that if I brushed with baking soda that it would whiten my teeth. I don't think this is true but I usually brush with it because I found that it is better for your teeth and it also doesn't leave that weird taste toothpaste does. Give it a try before a glass of orange juice and see what you think. This article goes more into detail why baking soda is good for your teeth and why toothpaste isn't as good and how they compare to each other.
