TikTok thrives on viral trends and clever hacks, with #TeethTok emerging as one of its latest obsessions. From whitening tricks to DIY orthodontics, the platform is awash with dental advice promising quick, affordable results. Yet, experts warn that many of these popular methods are not only ineffective but potentially harmful to oral health. Specialists fromCelebrate Dental and Braces, an affordable orthodontics provider, have scrutinised some of the most widespread TikTok teeth hacks, revealing the serious risks they pose.
The quest for a brighter smile drives much of this activity. The hashtag #teethwhitening features in over 483,000 posts, showcasing budget-friendly alternatives to professional treatments. Common suggestions include brushing with baking soda, swabbing with hydrogen peroxide, or, alarmingly, using bleach. While these may appear to lighten teeth temporarily, the consequences can be severe. Baking soda and hydrogen peroxide, when used excessively, erode enamel, the protective outer layer of teeth, heightening sensitivity and cavity risk. Bleach, a household cleaner, is outright dangerous, capable of damaging teeth and posing health risks if swallowed.
Safer options exist for at-home whitening. Dentists recommend ADA-approved whitening strips or toothpaste, which balance efficacy with safety. Some TikTokers advocate rubbing banana peels on teeth, claiming natural whitening benefits. Though harmless, this method lacks scientific backing and delivers no real results.
Another troubling trend involves shaping teeth with nail files, tagged in around 5,400 #teethfiling posts. Users attempt to smooth uneven edges, viewing it as a cheap fix for cosmetic flaws. However, filing strips away enamel permanently. Once gone, enamel cannot regrow, leaving teeth prone to decay and sensitivity. Professionals can contour teeth safely, but DIY attempts often backfire, marring smiles rather than enhancing them.
Costly orthodontic care has also sparked risky DIY solutions. Some TikTokers use rubber bands or hair elastics to shift teeth or close gaps, bypassing braces or aligners like Invisalign. This approach is fraught with danger. Misapplied pressure can damage tooth roots, potentially causing tooth loss. Orthodontists stress that only trained professionals can adjust teeth safely and effectively, safeguarding long-term oral health.
Oil pulling, an ancient practice involving swishing coconut or sunflower oil in the mouth, enjoys a modern revival on TikTok, with #oilpulling appearing in over 42,600 posts. Proponents claim it “pulls” bacteria and toxins, boosting gum health. While not inherently harmful, and possibly beneficial in reducing oral bacteria, oil pulling falls short as a standalone hygiene method. Without brushing and flossing, plaque and tartar can accumulate, inviting cavities and gum disease.
Perhaps most alarming is the use of metal dental tools to scrape plaque and tartar at home. Untrained hands wielding these instruments can scratch enamel or chip teeth, causing sensitivity. Worse, nicking gums with unsterilised tools risks infection or gum disease. Dental experts insist that plaque and tartar removal belongs in a professional’s hands, preserving both teeth and overall health.
Dr Kelcey Loveland from Celebrate Dental and Braces offered a stark assessment: “TikTok is a highly influential platform that can easily persuade users to try trending techniques aimed at achieving desired results. However, many of these teeth hacks are unproven and potentially dangerous. They often involve DIY methods and products that risk causing permanent, irreversible damage to teeth and gums.
“Hacks like using hydrogen peroxide, baking soda, and nail files can permanently erode and damage enamel. Since enamel does not regenerate, this leaves teeth vulnerable to sensitivity, staining, and decay. These so-called ‘hacks’ may lead to damage that ultimately requires costly dental repairs.
“The lack of professional guidance in these DIY techniques often results in harmful mistakes. What seems like a quick, inexpensive fix can leave your teeth in worse condition or appearance than before.
“In short, if you’re considering dental work or treatments, it’s far better to consult a professional dentist than to attempt these fixes yourself.”
