Fun fact: the sodium lauryl sulfate in toothpaste dulls the sweetness receptors on your tongue. The taste of orange juice after brushing your teeth is what it would ALWAYS taste like to cats.
But I also specifically use toothpaste that doesn't has sodium lauryl sulfate because it aggravates canker sores in my mouth. I wonder if this is why.
That being said, you still might be right, since the science behind canker sores is a crapshoot to begin with, as I've learned
Personally, what works for me is: If I bite my lip, or feel a sore coming on in general, I immediately have to wash it out. After that, the only way to prevent a full week+ long sore is to put alum (pickling spice) on it for 90 seconds or so, once or twice a day. And of course, I need to make sure I meticulously brush and floss after every meal (of course with toothpaste without laurel sodium sulfate) Usually I can suffice for the normal once or twice a day
And that being said, this isn't exactly scientific. This is 100% just correlation and gathering personal anecdotal data. If I happen to stumble across something better, I'll take it. But all things considered, it's not a particularly bad thing to suddenly feel the need to take extra care of my mouth once a month or so
Never tried chocolate after brushing my teeth but I don't find 99% / unsweetened dark chocolate particularly offensive.
Bet a friend/family member that they can’t taste the difference between whole/2%/1%/skim milk, or some combination thereof. Blindfold them and have them begin tasting the milks. Now, replace the last milk with orange juice. The brain prepares the body for milk, and the unexpected acidity usually causes a gag reflex, and sometimes vomiting. Keep a bucket handy:
I vowed that day to stop drinking OJ and stick to water.
I'm always wondering how so many people know of this first-hand.
Why are you drinking OJ, something extremely high in sugar, so soon after brushing your teeth?
I don't really get it since my mouth tastes like mint for 30 minutes after brushing, which makes food taste gross.
That's the best time to brush. Otherwise, all the bacteria and the like in your mouth have all night to fester.
I also brush after breakfast, but this is kinda of common knowledge so I'm surprised you don't seem to know it.
At some point, I heard that the opposite was true, ostensibly from a dentist on reddit. According to this anonymous stranger, after eating, your enamel is at its weakest, and you'll do the most damage to your teeth by brushing them. The reason was something about saliva and/or plaque that's been recently fed, I think.
(As a side note, some other dentist(?) in the same thread said that if you're going to brush your teeth once a day, it's most important to brush before going to bed.)
When I'm in a hurry I just get all done in the bathroom, including brushing teeth, and grab a quick breakfast on my way out, which usually involves half a glass orange juice.
Those are the situations where the toothpaste aftertaste can sometimes collide with orange juice, making it super bitter.
