From tongue scraping to mouth taping, the internet is packed with “dental hacks” promising fresher breath, whiter teeth, and even better sleep. But which of these trends actually work—and which might be quietly wrecking your smile?
Dr. Lawnin breaks down today’s most popular oral health fads, rating each from life-changing to downright harmful. Some, like tongue scraping and xylitol gum, truly promote a healthier mouth. Others—looking at you, oil pulling—offer little more than a placebo effect. And a few, such as mouth taping or alcohol-based mouthwash, could actually do more harm than good.
With a mix of professional insight and playful honesty (“Unless you wanna fund my vacations, don’t chew ice”), Dr. Lawnin separates fact from fiction in your daily dental routine.
Ready to find out which trends deserve a spot in your routine—and which belong in the trash? Let’s dive in.
Not all dental trends are created equal, some truly make your mouth cleaner and your smile brighter. According to Dr. Lawnin, a few popular habits deserve a permanent spot in your daily routine.
Let’s start with an underrated classic: tongue scraping. “It’s not going to stop anything,” Dr. Lawnin says, “but it is going to make your mouth healthier and smell better.” The science backs him up. The tongue’s surface harbors millions of bacteria that brushing alone can’t remove. Regular tongue scraping helps reduce bacterial buildup, improves your sense of taste, and keeps your breath fresher for longer.
Chewing gum after meals isn’t just about freshening your breath, it can also protect your teeth. Dr. Lawnin gives xylitol gum a solid 4 out of 5 for raising the mouth’s pH and preventing cavities. “It’s a great substitute when you can’t brush after eating,” he explains.
Xylitol, a natural sugar alcohol, prevents harmful bacteria from sticking to teeth and lowers acid levels that erode enamel. So next time you finish lunch at your desk, pop a piece of xylitol gum instead of running for your toothbrush.
Traditional flossing can feel like a chore, but Dr. Lawnin gives water flossers a near-perfect score—9 out of 10. “They’re awesome,” he says. “I still like floss for most people, but water flossers are a great alternative.”
Research shows that water flossers remove up to 99% of plaque in treated areas and are especially helpful for people with braces, implants, or sensitive gums.
Bottom line: Tongue scrapers, xylitol gum, and water flossers may not trend on TikTok every week, but they’re simple, science-backed tools that actually work.
Next up: What about those “natural” remedies everyone swears by? Let’s separate fact from fiction.
Some oral health fads fall into the “meh” category—not dangerous, but not exactly worth your time.
Coconut oil lovers, brace yourselves. Despite its popularity, oil pulling gets a big zero from Dr. Lawnin. “It does absolutely nothing,” he says bluntly. While the trend claims to “detox” the mouth and whiten teeth, there’s little scientific evidence to back it up.
Swishing oil for 15 minutes might make your mouth feel cleaner, but that’s due to rinsing, not the oil itself. It’s harmless, yes, but not a substitute for brushing or flossing.
Hydrogen peroxide mouth rinses sound like a DIY whitening miracle, but Dr. Lawnin only gives them a modest 3 out of 10. “It doesn’t necessarily hurt,” he notes, “but it won’t make a massive benefit either.”
Used occasionally, hydrogen peroxide can kill bacteria and help minor gum irritation. Overused, though, it can dry out your mouth and irritate soft tissues. Stick to dentist-approved whitening solutions instead of homemade chemistry experiments.
The takeaway: Not every trend is harmful, but not every one helps either. Save your time—and your enamel—for proven habits that truly improve your oral health.
Next, Dr. Lawnin gets real about the dental trends that are not just useless—but downright dangerous.
Now for the harsh truth: some “wellness hacks” are actually hurting people’s teeth and gums. Dr. Lawnin doesn’t sugarcoat it—these are the trends you need to stop immediately.
Mouth taping has gone viral as a “sleep hack,” claiming to promote nasal breathing. But Dr. Lawnin gives it a negative three. “Bad, bad deal,” he warns. “Most people are doing it without consulting their physician or sleep medicine doctor—and it causes lots of problems.”
Taping your mouth shut can worsen sleep apnea, increase anxiety, and even lead to breathing interruptions. Unless prescribed by a doctor, skip this one altogether.
If you love crunching ice, Dr. Lawnin has some news for you: stop. Now. “Unless you wanna fund my vacations, don’t do it,” he jokes. Ice chewing might feel satisfying, but it wreaks havoc on your teeth—causing cracks, chips, and enamel erosion.
Real-world example? Countless patients show up in dental chairs with broken molars from the habit. The cold shock and pressure from ice are a one-two punch your enamel can’t handle.
That burning sensation after a swig of alcohol-based mouthwash might feel like it’s “killing germs,” but according to Dr. Lawnin, it’s actually doing more harm than good. He rates it a negative 10, calling alcohol mouthwash “horrendous.”
Studies have linked frequent use of alcohol-based rinses to a higher risk of oral cancer. “You get the burn,” Dr. Lawnin explains, “but it increases your risk of oral cancer.” For fresher breath without the damage, choose an alcohol-free rinse instead.
Bottom line: The most dangerous dental fads aren’t just ineffective—they can cause lasting harm. Always check with a professional before trying the next viral trend.
Now that we’ve covered the good, the bad, and the downright dangerous, let’s wrap up with what Dr. Lawnin wants every reader to remember about oral health in the digital age.
When it comes to oral health, the internet can be both a goldmine and a minefield. For every genuinely helpful tip, there’s a viral trend waiting to undo your hard work. As Dr. Lawnin reminds us, not all that glitters in your feed is gold for your gums.
The winners? Simple, science-backed habits like tongue scraping, xylitol gum, and water flossers—easy, effective additions that truly make a difference. The middle ground? Trends like oil pulling or hydrogen peroxide rinses that might feel satisfying but don’t do much long-term. And the clear losers? Mouth taping, alcohol-based mouthwash, and ice chewing—habits that can chip away at your oral health, literally and figuratively.
The key takeaway is simple: before trying the next “miracle” dental hack, ask a professional. Your mouth deserves expert care, not crowd-sourced advice.
