Oil pulling: what the evidence says (and doesn't)
Oil pulling is a traditional practice with limited scientific support. It should not replace brushing, flossing, and professional dental care—but we explain what research actually shows.

What is oil pulling?
Oil pulling is a traditional practice in which people swish oil—often coconut, sesame, or sunflower oil—in their mouth for an extended period, usually 15–20 minutes, before spitting it out. Proponents claim it removes toxins, whitens teeth, and improves gum health. It has gained popularity as a natural wellness trend in recent years.
What does the research show?
The American Dental Association has reviewed oil pulling, and the evidence for its benefits is limited. While a small number of laboratory and short-term clinical studies have suggested oil pulling may reduce certain bacteria in the mouth, these studies are not large enough or rigorous enough to prove it works better than established oral hygiene methods.
No credible research shows that oil pulling is more effective than brushing with fluoride toothpaste or flossing for preventing cavities or gum disease. The scientific evidence that supports brushing, flossing, and professional dental care is far stronger and based on decades of large-scale studies.
The replacement risk
The biggest concern with oil pulling is not that it will harm you, but that it might replace the habits we know work. If you spend 20 minutes oil pulling and skip brushing or flossing, your teeth and gums lose out. If oil pulling makes you feel like you don’t need to visit your dentist, problems like early cavities, gum disease, or oral cancer can go undetected.
Delaying professional care because you are relying on an unproven home remedy is a genuine risk to your oral health.
What does work
You already know the foundation: brush twice daily with a fluoride toothpaste, floss daily, and see your dentist at least twice a year for checkups and cleanings. If you want to learn more about why these routines matter, read our guides on brushing and flossing techniques and how fluoride protects your teeth.
If you are interested in mouthwash as a complement to brushing and flossing, we break down which types have evidence behind them.
A balanced take
Oil pulling is a traditional practice, and enjoying a wellness ritual is valid. If it genuinely appeals to you and fits into a routine that includes proven habits—not instead of them—then trying it is your choice. Just do not let it become an excuse to skip brushing, flossing, or dental visits.
The bottom line: oil pulling is not a substitute for fluoride toothpaste, dental floss, or professional care. If you are looking to improve your oral health or prevent disease, stick with methods backed by strong evidence.

Frequently asked questions
Will oil pulling replace my regular brushing and flossing?
No. Oil pulling has not been shown to substitute for brushing twice daily with fluoride toothpaste, flossing daily, or professional cleanings. Skipping proven habits to rely on oil pulling can allow cavities, gum disease, and other problems to develop unnoticed.
Is oil pulling safe to do?
Oil pulling itself (swishing oil in your mouth) is unlikely to cause harm if you don't swallow large amounts. However, it takes time, and if it crowds out brushing, flossing, or dental visits, it can indirectly harm your teeth and gums.
Can I use oil pulling alongside my normal routine?
If you enjoy it and it doesn't delay or replace brushing, flossing, or seeing your dentist, adding oil pulling to your routine is a personal choice. Just understand it is not a clinically proven substitute for evidence-based oral hygiene.
