Key Takeaway
Coconut oil pulling significantly reduces plaque and gingivitis indices comparable to chlorhexidine mouthwash, though evidence quality remains low to moderate.
Summary
This systematic review evaluated six clinical studies examining the effects of oil pulling with coconut oil on dental hygiene and oral health. The review included both randomized controlled trials and quasi-experimental studies with a combined participant pool spanning adolescents and adults.
Results showed that coconut oil pulling significantly reduced plaque index scores and gingival bleeding, with effects comparable to chlorhexidine mouthwash in several trials. The lauric acid in coconut oil was identified as a key antimicrobial agent, capable of inhibiting Streptococcus mutans and other cariogenic bacteria through saponification and emulsification mechanisms.
However, the authors noted that the overall quality of evidence was low to moderate, with small sample sizes and short study durations being common limitations. The review concluded that while coconut oil pulling shows promise as a complementary oral hygiene practice, more rigorous large-scale RCTs are needed to establish definitive clinical guidelines.
