Welcome to DentalTok: a world of pearly whites, DIY hacks, and supposed “quick fixes,” all promising a healthier smile.
From BookTok to TravelTok, TikTok has become a hub for just about every niche imaginable. These “Toks” bring people with shared interests together to share ideas and learn from one another. So, of course, dentistry has found its corner of TikTok, too.
Honestly, some of these tips may have a little truth behind them … but many can actually permanently damage your teeth. And when a viral video makes a hack look quick and easy, it isn’t always obvious which is which.
At Eggert Family Dentistry, we believe education is one of the most powerful tools for protecting your health. Dr. Elizabeth Eggert and Dr. Jeff Eggert look beyond the promise of a quick fix to consider what a trend is really doing to your teeth — and whether it addresses the underlying issue, or simply masks it.
So, which viral dental hacks have some science behind them, and which should stay safely on your “For You Page” (FYP)?
Lemon Juice & Banana Peels

Verdict: ❌ Not Approved
This viral dental hack claims that rubbing a banana peel against your teeth before swishing with lemon juice will help whiten your teeth. According to this DentalTok myth, the potassium in the banana peel is supposed to wipe away surface stains, while the citric acid in lemon juice breaks down deeper discoloration.
Sounds like a pretty sweet deal for two ingredients sitting in your kitchen! Unfortunately, your teeth probably won’t find this particular fruit salad quite as appealing.
Lemon juice is highly acidic and repeatedly exposing your teeth to that acidity can gradually wear away their protective enamel. And as enamel becomes thinner, more of the darker dentin underneath becomes visible — not to mention, your teeth also become more susceptible to decay.
As for the banana peel? Well, it’s certainly the friendlier half of this trend, but there isn’t evidence that rubbing one on your teeth will provide genuine whitening results. We’d recommend simply enjoying your banana as a “tooth-friendly” snack and using your toothbrush to take care of surface stains (in between routine professional recare appointments, that is!).
Charcoal Toothpaste

Verdict: ⚠️ Proceed with Caution
DentalTok loves this one. The dramatic before-and-after videos tend to spread like wildfire — and, considering you’re starting with black paste all over your teeth, it’s no wonder your smile looks so much whiter by comparison!
And hey, there is a little truth behind the trend. Charcoal is abrasive, so as you brush, it can help scrub away some of the surface stains that make teeth look dull.
Unfortunately, that abrasiveness isn’t so friendly to your enamel. Over time, abrasive charcoal toothpaste can wear away at this protective outer layer, eventually contributing to sensitive and yellowing teeth. Plus, charcoal only tackles stains on the surface of your teeth; research hasn’t shown it to be particularly effective at changing their deeper, intrinsic color. Many charcoal toothpastes also lack fluoride, an important ingredient for protecting teeth against cavities.
So, before reaching for that trendy black goo in a tube, take a moment to consider the tradeoff. A maybe-slightly-brighter smile isn’t worth being rough on the enamel you want to keep it healthy for life!
The Eggert-Approved Alternative
For patients interested in whitening toothpastes, Dr. Elizabeth Eggert and Dr. Jeff Eggert recommend gentler options, such as Sensodyne True White. These products are much less abrasive, carefully balancing stain removal with enamel protection.
But, for more noticeable (and safer!) results, professional whitening is the way to go. At Eggert Family Dentistry, we offer several options, including KöR Whitening Deep Bleaching, Philips Zoom Whitening Treatments, Professional-Grade Strips, and at-home Whitening Trays. We’ll help you find an option that fits your smile while keeping your overall oral health front and center.
Oil Pulling

Verdict: ✅/⚠️ Approved, but With Caution
Oil pulling has been around for over 3,000 years, with roots tracing back to ancient India and the practice of Ayurvedic medicine. It faded from the public eye for a while (okay, for a few thousand years), but thanks to DentalTok, it’s making a comeback!
The practice involves swishing an edible oil around your mouth for about 10 minutes before spitting it out. Modern fans claim oil pulling can reduce bacteria, cure cavities, and freshen breath.
So, how much of that is true? Let’s break it down.
Does oil pulling reduce bacteria buildup?
A little, yes! Research suggests oil pulling can reduce levels of certain harmful bacteria in the mouth.
Does oil pulling cure cavities?
No. Once a cavity has begun to form, it cannot be swished away with oil. The affected tooth needs attention from a dental professional.
Does oil pulling freshen breath?
It can! If odor-causing bacteria are behind your bad breath, reducing some of that bacteria may help. But persistent bad breath can also point to an underlying concern, such as tooth decay or more often periodontal disease or gingivitis. In those cases, freshening your breath only addresses the symptom. We want to identify and treat the cause.
So, do we recommend it? Not really. There may befaster, more effective options out there for keeping your mouth fresh and healthy. But will oil pulling hurt your smile? Probably not! If you enjoy it, there’s generally no harm in adding it to your routine — just don’t let it take the place of brushing, flossing, and other adjuncts recommended by Dr. Elizabeth Eggert or Dr. Jeff Eggert!
Rubber Bands to Close Gaps

Verdict: ❌ Not Approved
This viral dental hack encourages viewers to use small rubber bands to close gaps between their teeth at home. According to DentalTok, wrapping a band around two teeth puts enough pressure on them to gradually pull them closer together.
Unfortunately, there are some pretty serious risks hiding behind this seemingly simple hack. A rubber band can slip beneath the gumline, where it can damage the gums and supporting bone around your teeth. That damage can cause teeth to become loose, shift even further out of place, or potentially fall out altogether. And trust us, the gap left by a fully missing tooth is much harder to fix than a little extra spacing!
The Eggert-Approved Alternative
For some patients, the best solution to unwanted gapping may be Invisalign. Invisalign clear aligners are a set of custom plastic trays that slowly shift your teeth into the desired position. They function similarly to traditional braces, but they’re much more discreet.
Dr. Elizabeth Eggert is highly trained in the Invisalign system, which means Eggert Family Dentistry patients can complete this type of orthodontic treatment right here in our office. No rubber bands from the junk drawer required!
Tongue Scraping

Verdict: ✅ Approved
Now this is a viral dental hack we can get behind! Tongue scraping is when you … well, scrape your tongue (clever name, right?). You might have noticed those U-shaped tools popping up more frequently in the oral hygiene aisle. Simply glide the scraper along your tongue to remove buildup as part of your daily oral care routine.
A lot of that buildup is made up of bacteria, dead skin cells, and food debris — all things Dr. Elizabeth Eggert and Dr. Jeff Eggert are happy to send packing! A few of the benefits include:
- Fresher breath. Odor-causing bacteria love to hang out on the tongue. Removing that buildup can help keep your breath feeling fresher.
- A cleaner-looking tongue. Scraping away buildup can reduce the white or yellow coating on your tongue, leaving it looking pinker and healthier.
- Better oral hygiene. Your tongue can harbor bacteria that contribute to plaque buildup and gum inflammation. Regularly removing some of those bacteria helps support a healthier environment throughout your mouth.
Just remember: tongue scraping is an addition to a healthy oral care routine, not a replacement for brushing and flossing. But as far as DentalTok trends go? This one gets a thumbs-up from Eggert Family Dentistry!
Teeth Filing with a Nail File

Verdict: ❌ ABSOLUTELY NOT APPROVED
This may be the craziest viral dental hack we’ve seen yet. It encourages people to literally file their teeth down with a nail file. Some users are trying to shorten prominent or uneven teeth. Others are going for something a little more out of pocket, like vampire fangs or American Girl doll-style teeth (yes, really).
But filing your teeth can cause serious, irreversible damage. How serious? Well, that depends on how far you file:
Through the enamel: Enamel is the hard outer layer that protects your teeth, and once it’s gone, it doesn’t grow back. Removing too much leaves the softer layers underneath more vulnerable to bacteria, decay, sensitivity, and further damage.
↓
Down to the dentin: Beneath your enamel is dentin, which has a naturally more yellow appearance and contains tiny tubules that connect toward the nerve of the tooth. Exposing it can make your teeth much more sensitive to hot, cold, sweet, and acidic foods and drinks. Dentin exposure puts the tooth at extremely high risk for decay.
↓
Into the pulp: Go even deeper and you can reach the pulp, the innermost part of your tooth containing nerves and blood vessels. Damage here can cause severe pain and may require a root canal and crown to save the tooth. If a tooth becomes too damaged to restore, it may even need to be extracted and replaced.
No matter how far you go, the damage can be serious enough to require extensive dental repair work. And even if you don’t feel immediate pain, the effects can catch up with you down the road. Changing the shape of your teeth messes with your bite, which can impact your jaw alignment, too. From there, the effects can ripple outward, impacting everything from your temporomandibular joints (TMJs) to your airway and quality of sleep.
If you’re interested in cosmetic dentistry, keep the nail file far, far away from your teeth! Dr. Elizabeth Eggert and Dr. Jeff Eggert can help you explore a safe way to reshape your smile while protecting the healthy tooth structure you already have.
Final Verdict? Leave It to the Professionals
Before trying the next viral dental hack, ask yourself one question: Would I rather trust TikTok … or my dentist?
If you’re looking to whiten your smile, straighten your teeth, repair chipped teeth, or simply improve your oral health, Dr. Elizabeth Eggert and Dr. Jeff Eggert can recommend safe treatments that deliver long-lasting results — without risking permanent damage. And remember, the dentists at Eggert Family Dentistry come with over 40 years of clinical experience, we’re thinking the TikTok’ers can’t claim anything close to that fact!
