Oil Pulling for Dental And Oral Health

Research suggests that oil pulling — the practice of swishing edible oils such as sesame or coconut oil in the mouth — may offer modest benefits for oral hygiene, including reductions in dental plaque, gum inflammation, salivary bacterial counts, and bad breath, with several small randomized controlled trials and systematic reviews reporting outcomes comparable to chlorhexidine mouthwash across these measures. Studies indicate that both sesame and coconut oil have been investigated, with some trials finding meaningful plaque reductions and others, including a 2025 RCT comparing sesame oil to plain distilled water, suggesting that the mechanical act of swishing liquid may account for much of the observed benefit rather than any property specific to oil. A 2024 meta-analysis pooling 25 trials found oil pulling outperformed non-chlorhexidine mouthwashes for gum health but fell short of chlorhexidine for plaque reduction, while a 2022 meta-analysis found significant reductions in salivary bacteria but no meaningful differences in plaque or gum inflammation scores, illustrating how findings vary depending on what is measured and how studies are designed. Across the full body of evidence, researchers consistently note important limitations including small sample sizes, short study durations, high risk of bias, and overall very low evidence quality, meaning the current research is encouraging but insufficient to draw firm conclusions about oil pulling as a reliable or standalone oral health intervention.
