From charcoal toothpaste to oil pulling, TikTok is overflowing with DIY dental hacks that promise a brighter, cleaner teeth whitening experience. But many of these viral trends come with hidden risks that can permanently harm your teeth and gums. Canadians scrolling through their feeds are often left wondering what actually works and what could send them straight to the dentist.
In this article, we’ll break down the science behind the most popular TikTok dental trends, separating myth from reality. You’ll also discover safer, dentist-approved alternatives for maintaining a healthy, radiant smile, supported by evidence, not algorithms.
Are TikTok Dental Trends Safe? A Dentist’s Overview
Social media rewards visual results, fast, dramatic, and often unverified. Most creators behind TikTok dental trends aren’t dental professionals, and their hacks skip the scientific testing that ensures safety and effectiveness. What looks like a “miracle whitening fix” can actually strip enamel or irritate gums.
Dentists across Canada have warned that following unverified trends can cause irreversible enamel erosion, tooth sensitivity after teeth whitening, and gum damage. Before trying any hack, it’s wise to consult your general dentist or book a professional dental cleaning to safely improve your smile.
Here’s what Advanced Health says:
“TikTok is a hub for creative ideas, hacks, and trends, but not everything that goes viral on the platform is beneficial—especially when it comes to your health. Dental trends are one of the areas where misinformation can spread quickly, often leading to practices that are not just ineffective but downright harmful.”
Charcoal Toothpaste: What the Evidence Says
Charcoal toothpaste has become a viral sensation, often marketed as a natural way to “detox” and whiten teeth. But according to clinical studies, there’s little evidence supporting its whitening claims. Activated charcoal’s abrasive particles can actually wear away enamel, the tooth’s protective layer, leading to sensitivity and long-term discoloration.
Unlike fluoride toothpaste, most charcoal formulas lack the minerals needed to strengthen enamel or prevent cavities. Over time, this can increase the risk of dental caries and gum irritation. Dentists recommend using gentle, fluoride-based toothpaste or scheduling professional whitening treatments for proven, lasting results.
If you’re already noticing dullness or gray staining after using charcoal products, your dentist can provide enamel-remineralizing solutions to help restore your natural shine.

Oil Pulling: Ancient Practice or Overhyped Trend?
Oil pulling, swishing coconut or sesame oil in the mouth, is another popular trend revived by TikTok. Supporters claim it “removes toxins” and “naturally whitens teeth.” While oil pulling may help reduce bacteria on the tongue, there’s no strong scientific evidence that it can replace brushing, flossing, or professional care.
Dentists agree that oil pulling should only be considered a supplemental habit, not a substitute for proper oral hygiene. It doesn’t remove plaque effectively or protect against cavities like fluoride treatments or routine dental checkups do.
In fact, skipping regular brushing in favour of oil pulling can lead to plaque buildup, gum inflammation, and periodontal disease over time, which will definitely require periodontics.
Other TikTok Trends to Be Careful With
TikTok’s influence on oral care doesn’t stop at charcoal and oil. New trends appear weekly, some harmless, others dangerous.
Among the most concerning:
- DIY Whitening with Lemon or Baking Soda: The acid from lemon juice and the abrasiveness of baking soda erode enamel quickly, causing lasting sensitivity.
- Hydrogen Peroxide Rinses: Over-the-counter peroxide is too harsh for daily use and can burn soft tissues.
- Filing Teeth at Home: A viral yet extremely damaging trend, this permanently removes enamel, often requiring cosmetic dentistry to repair the damage.
- Magic Whitening Pens: Many contain unregulated ingredients that can irritate gums or bleach unevenly.
If your teen is experimenting with these viral fads, encourage them to discuss safer options with their family dentist before trying anything new.
