Orange Juice and Toothpaste
Everybody’s day starts a little differently, but we can agree brushing your teeth should always be a part of your morning routine!
Are you a before-breakfast brusher? If so, you know the dreaded orange-juice-and-toothpaste taste that can follow! Orange juice is bitter and cereal with milk tastes strange! It’s only temporary, but it can really put you off your breakfast!
Why does food taste so bad right after you brush your teeth?
The reason for this bad taste is sodium lauryl ether sulfate, known as SLES or SLS (sodium laureth sulfate), which makes toothpaste foamy and disperses it around the teeth. However, sodium laureth sulfate is not as helpful when it comes to the tongue. Although completely harmless, sodium laureth sulfate suppresses the taste bud receptors for sweetness, and amplifies the taste bud receptors for bitterness. This heightened sensitivity to bitterness and dulling of sweetness is what makes your breakfast taste so strange.
Your tongue is covered with taste-sensitive cells spotted with proteins. If a particle of food you have eaten hits one of these cells, it sends a message to your brain signaling which taste sensation it is; sweet, bitter, sour, salty or umami.
Sodium laureth sulfate is a “detergent” molecule, which disperse fat molecules. This works in soaps for your body, hair or dishes. However, SLS affects the membranes of our tongue cells, blocking our sweet taste buds and enhancing our bitter taste. This results in the unpleasant flavor you get drinking orange juice after the SLS in your toothpaste has dulled your taste buds!
It is only temporary, but if it bothers you, try purchasing a toothpaste made without sodium laureth sulfate (SLS). However, keep in mind that some of these natural toothpastes may also be made without fluoride. Fluoride is absolutely essential in strengthening tooth enamel and preventing cavities.
