The verdict
Pleasant, cheap, and low-risk. The plaque and breath benefits in small trials are real but modest, and the whitening claims attached to oil pulling generally are not supported. Treat it as an addition to brushing and flossing, never a replacement.
Dry mouth, morning breath, and anyone who wants a non-alcohol alternative to mouthwash.
You expect a shade change or a substitute for flossing.
What the evidence supports
Small randomized trials have found reductions in plaque scores and gingival indices with daily coconut oil pulling over two to four weeks. The effect sizes are modest and the study quality is mixed — enough to call it a reasonable adjunct, not enough to call it therapy.
The practical part
Ten minutes is the realistic floor, twenty the ceiling. Spit into the trash, not the sink — coconut oil solidifies in pipes. Do not swallow.

Common questions
Morning or night?
Morning, before brushing, is the traditional and most practical slot.
