Oil Pulling
Small trials show it beats doing nothing and loses to chlorhexidine. It does not whiten teeth, and the detox claims have no mechanism at all.
Also called: coconut oil pulling · oil swishing · ayurvedic mouth rinse
Verdict — cope
The mechanism does not hold. Your time is better spent elsewhere.
Evidence grade C
Mechanistic plausibility, small studies, or observational data. Suggestive, not established.
Mechanism
Swishing oil mechanically dislodges plaque and the oil emulsifies some surface debris. There is no pathway by which oral tissue extracts systemic toxins, which is the claim the practice is usually sold on.

The full read
The dental trials are small and mostly positive against a no-treatment control, which is a low bar — any twenty minutes of swishing anything would move plaque indices. Against chlorhexidine it loses. It does not whiten teeth: no bleaching agent is involved, and reported whitening is removal of surface film, which brushing also achieves in two minutes. Harmless apart from occasional lipoid pneumonia from aspiration and a plumbing bill when solidified coconut oil meets a cold drain. Twenty minutes a day is the real cost; `teeth-whitening` is the evidenced route to the outcome people want here.
