Dentist explains the 3 times you should never brush your teeth
Sometimes not brushing your teeth is the best way to protect them.

Add this to the list of things you didn't learn in health class.
For those who love the oh-so fresh feeling of immediately running to brush their teeth after a meal, we got some bad news.
London-based dental surgeon and facial aesthetics practitioner Dr. Shaadi Manouchehri recently shocked around 12 million viewers on TikTok after sharing the three occasions when you should “never” be scrubbing those pearly whites—if you want to actually protect your teeth, that is.
The hardest part about this video, which some viewers are undoubtedly still processing, is that each of these no-no times is exactly when brushing your teeth is the only thing you’ll want to do. So much for instincts.
Number one on Manouchehri’s list, which caused the most controversy in the comments, is right after vomiting. Yep, you read that right.
“This is because the contents of the stomach are extremely acidic and the mouth is already in a very acidic state so if you brush straight after [vomiting] you’re basically wearing away your enamel,” Manouchehri explained.
Of course, commenters weren’t willing to let this one go without a fight. One viewer wrote, “I would rather lose all of my teeth than not brush after vomiting.”
Manouchehri also says to avoid brushing your teeth directly after eating breakfast. This is because “when you’ve just eaten, the mouth is, again in a “very acidic state,” so if you’re brushing your teeth you’re rubbing that acid on the tooth, which wears down the enamel.” Other sources have also confirmed that brushing your teeth tight after any meal isn’t really recommended.
This goes double for right after sweets.
Manouchehri says to wait a full 60 minutes before putting a toothbrush anywhere near your mouth after having something sugary. Because…you guessed it…acid.
Does this advice seem counterintuitive? Don’t worry, you’re not alone.

“Ah, yes, the three times I want to brush my teeth more than any other time,” one person joked.
Luckily, there are few alternatives to try if you want that good, clean mouth feeling but don’t want to compromise your enamel—the simplest being to either rinse with or drink water. You can also use sugar-free chewing gum or conclude your meal with dairy or non-acidic foods, according to Advanced Dental Associates. If you still crave a little more of a hygiene bang, you can opt for a mouthwash with fluoride and using a tongue cleaner, which removes excess acid, per Curetoday.com.
Guess there’s a time and a place for everything, even when it comes to dental hygiene.

There's a reason why some people can perfectly copy accents, and others can't
Turns out, there's a neurodivergent link.

Have you ever had that friend who goes on vacation for four days to London and comes back with a full-on Queen's English posh accent? "Oooh I left my brolly in the loo," they say, and you respond, "But you're from Colorado!" Well, there are reasons they (and many of us) do that, and usually it's on a pretty subconscious level.
It's called "accent mirroring," and it's actually quite common with people who are neurodivergent, particularly those with ADHD (Attention Deficit Hyperactivity Disorder). According Neurolaunch, the self-described "Free Mental Health Library," "Accent mirroring, also known as accent adaptation or phonetic convergence, is the tendency to unconsciously adopt the accent or speech patterns of those around us. This linguistic chameleon effect is not unique to individuals with ADHD, but it appears to be more pronounced and frequent in this population."
Essentially, when people have conversations, we're constantly "scanning" for information—not just the words we're absorbing, but the inflection and tone. "When we hear an accent, our brains automatically analyze and categorize the phonetic features, prosody, and intonation patterns," writes Neurolaunch. For most, this does result in copying the accent of the person with whom we're speaking. But those with ADHD might be more sensitive to auditory cues. This, "coupled with a reduced ability to filter out or inhibit the impulse to mimic…could potentially explain the increased tendency for accent mirroring."
While the article explains further research is needed, they distinctly state that, "Accent mirroring in individuals with ADHD often manifests as an unconscious mimicry of accents in social situations. This can range from subtle shifts in pronunciation to more noticeable changes in intonation and speech rhythm. For example, a person with ADHD might find themselves unconsciously adopting a Southern drawl when conversing with someone from Texas, even if they’ve never lived in the South themselves."
People are having their say online. On the subreddit r/ADHDWomen, a thread began: "Taking on accents is an ADHD thing?" The OP shares, "My whole life, I've picked up accents. I, myself, never noticed, but everyone around me would be like, 'Why are you talking like that??' It could be after I watched a show or movie with an accent or after I've traveled somewhere with a different accent than my 'normal.'
They continue, "Apparently, I pick it up fast, but it fades out slowly. Today... I'm scrolling Instagram, I watch a reel from a comedian couple (Darcy and Jeremy. IYKYK) about how Darcy (ADHD) picks up accents everywhere they go. It's called ADHD Mirroring??? And it's another way of masking."
(The OP is referring to Darcy Michaels and his husband Jeremy Baer, who are both touring comedians based in Canada.)
Hundreds of people on the Reddit thread alone seem to relate. One comments, "Omfg I've done this my whole life; I'll even pick up on the pauses/spaces when I'm talking to someone who is ESL—but English is my first language lol."
Sometimes, it can be a real issue for those around the chameleon. "I accidentally mimicked a waitress's weird laugh one time. As soon as she was out of earshot, my family started to reprimand me, but I was already like 'oh my god I don’t know why I did that, I feel so bad.'"
Many commenters on TikTok were shocked to find out this can be a sign of ADHD. One jokes, "Omg, yes, at a store the cashier was talking to me and she was French. She's like 'Oh are you French too? No, I'm not lol. I'm very east coast Canada."
And some people just embrace it and make it work for them. "I mirror their words or phrase! I’m 30. I realized I start calling everyone sweetie cause my manager does & I work at coffee shop."
