From Dr. Michelle Messina, Trusted Cosmetic and Family Dentist in Louisville, Colorado
Social media isn’t just for dance trends and recipes anymore — TikTok dentists are helping millions of people learn how to take better care of their smiles. While not everything you see online is accurate, many licensed dentists are sharing simple, science-backed oral health tips that truly make a difference.
At Michelle N. Messina, DDS, Dr. Messina loves seeing patients in Louisville, Colorado and the surrounding communities of Boulder Valley take an active interest in their oral health — especially when online trends promote healthy habits. Below are some of the best oral health tips trending on TikTok, along with Dr. Messina’s professional insight into what truly supports a healthy smile.
Brush Gently — Harder Is Not Better
TikTok tip: Use light pressure and let the toothbrush do the work.
Many TikTok dentists demonstrate how brushing too hard can wear down enamel and irritate gums. Over time, aggressive brushing may lead to tooth sensitivity and gum recession.
Dr. Messina recommends:
- Use a soft-bristled toothbrush
- Brush twice daily for two minutes
- Use gentle, circular motions
Flossing Before Brushing May Be More Effective
TikTok tip: Floss first, then brush.
This trend is actually supported by research. Flossing first removes plaque and debris so fluoride toothpaste can better reach between teeth.
Dr. Messina recommends:
- Floss once daily
- Be gentle — no snapping
- Curve the floss around each tooth
Don’t Forget to Clean Your Tongue
TikTok tip: Tongue cleaning reduces bacteria and bad breath.
TikTok dentists often highlight the tongue as a major source of odor-causing bacteria that brushing alone may miss.
Dr. Messina recommends:
- Use a tongue scraper or toothbrush
- Gently clean from back to front
- Rinse afterward
It’s Not Just Sugar — It’s How Often You Snack
TikTok tip: Frequent snacking increases cavity risk.
Even healthy snacks can increase cavity risk when eaten throughout the day. Frequent snacking keeps the mouth acidic longer, giving bacteria more time to damage enamel.
Dr. Messina recommends:
- Limit grazing between meals
- Drink water after snacks
- Enjoy sweets with meals instead of alone
Teeth Grinding Isn’t “Normal” — Even If You Don’t Notice It
TikTok tip: Jaw pain or headaches may signal nighttime grinding.
Many TikTok dentists show real examples of damage caused by bruxism, which often occurs during sleep and goes unnoticed.
Dr. Messina recommends:
- Pay attention to jaw soreness or morning headaches
- Address grinding early to prevent tooth damage
- Use a custom night guard when indicated
Be Careful With DIY Whitening Hacks
TikTok tip: Lemon juice, charcoal, and baking soda can harm enamel.
Dr. Messina agrees with TikTok dentists — many viral whitening hacks can permanently damage enamel and increase sensitivity.
Dr. Messina recommends:
- Avoid abrasive or acidic DIY whitening
- Choose dentist-approved whitening treatments
- Always ask before trying a trend
Regular Dental Visits Matter — Even If Nothing Hurts
TikTok tip: Dental problems don’t always cause pain early.
One of the most important messages from TikTok dentists is that cavities and gum disease often begin silently — without obvious symptoms.
Dr. Messina recommends:
- Schedule regular dental exams and cleanings
- Detect issues early for simpler treatment
- Protect your long-term oral health
