The Truth About TikTok Dental Trends: Oil Pulling, DIY Braces & More

     

     Social media, especially TikTok, has become a powerhouse for trends—some fun and harmless, others downright dangerous. When it comes to dental health, many viral trends claim to offer quick fixes, but do they actually work? Let’s take a closer look at some of the most popular TikTok dental trends, what science has to say, and whether they’re worth trying—or avoiding at all costs.

1. Oil Pulling: Ancient Practice or Overhyped Trend?

Oil pulling involves swishing coconut or sesame oil in your mouth for 15–20 minutes before spitting it out. This practice has been around for centuries and is often touted as a natural way to remove toxins and whiten teeth.

The Truth: While oil pulling may help reduce bacteria in the mouth and improve gum health, it is not a substitute for brushing and flossing. Scientific studies suggest that it can help with bad breath and mild plaque buildup, but it won’t whiten teeth significantly or replace professional dental care. If you enjoy oil pulling, there’s no harm in adding it to your routine, but don’t expect miracle results.

2. DIY Braces: A Dangerous Shortcut

Some TikTok users have shared videos showing how to straighten teeth at home using rubber bands, paper clips, or other household items.

The Truth: This trend is extremely dangerous. Orthodontists spend years training to move teeth safely, and DIY braces can cause severe damage. Using rubber bands or other makeshift materials can lead to tooth loss, gum infections, and irreversible harm to your bite alignment. If you want straighter teeth, consult a professional for options like Invisalign or traditional braces—never attempt to move your teeth at home.

3. Whitening With Baking Soda and Lemon Juice

Many TikTok users swear by this natural method, claiming that applying a paste made of baking soda and lemon juice can instantly whiten teeth.

The Truth: While baking soda can help remove surface stains, lemon juice is highly acidic and can erode enamel, making teeth more sensitive and prone to cavities. The combination of baking soda and lemon juice can do more harm than good. If you want whiter teeth, opt for dentist-approved whitening treatments instead.

4. Hydrogen Peroxide as a Whitening Rinse

Some influencers suggest rinsing with hydrogen peroxide to achieve a brighter smile.

The Truth: Hydrogen peroxide is an active ingredient in many professional whitening treatments, but using it incorrectly can be harmful. Overuse or high concentrations can cause gum irritation and enamel damage. If you want to use hydrogen peroxide, it’s best to follow your dentist’s guidance or use professionally formulated whitening products.

5. Filing Teeth With a Nail File

One of the most shocking trends on TikTok involves people filing down their teeth with nail files to make them appear straighter or more even.

The Truth: This is one of the most damaging dental trends ever. Unlike nails, tooth enamel does not grow back. Filing your teeth can permanently damage them, leading to sensitivity, chipping, and decay. If you’re unhappy with the shape of your teeth, seek professional cosmetic treatments like bonding or veneers—never take a nail file to your enamel.

6. “Veneer Check” Trend

Many TikTok users show off their “veneers” by revealing their dramatically shaved-down teeth, often misleading viewers into thinking they are getting veneers when they’re actually receiving full-coverage crowns.

The Truth: True veneers require minimal enamel removal, while full crowns involve shaving down a significant portion of the tooth. Some influencers don’t realize the difference and unknowingly promote irreversible dental procedures. If you’re considering cosmetic dentistry, consult a licensed professional to understand your options and avoid unnecessary damage.

The Bottom Line: Trust the Experts

While social media can be a great place for inspiration and education, it’s not always a reliable source for medical or dental advice. Many TikTok dental trends are misleading or downright harmful. When in doubt, consult a professional before trying any dental hack you see online. Your smile is worth protecting!
