Is oil pulling effective for preventing dental caries (tooth decay)?

From the Guidelines

Oil pulling is not recommended as a primary treatment for preventing dental caries (tooth decay) due to insufficient scientific evidence supporting its effectiveness against cavities. The most effective approach to preventing dental caries is through the use of fluoride, as evidenced by studies such as 1, which highlights the importance of fluoride in reducing the incidence of dental caries and slowing or reversing the progression of existing lesions.

Key points to consider for preventing dental caries include:

• Brushing twice daily with fluoride toothpaste, as recommended by 1
• Flossing daily to remove plaque and bacteria
• Limiting sugary foods and drinks, which contribute to the development of dental caries
• Visiting a dentist regularly for check-ups and professional cleanings to catch and treat any potential issues early

While oil pulling may have some temporary benefits in reducing oral bacteria, it is not a substitute for conventional dental care and should not be relied upon as a primary method for preventing dental caries. If you still wish to try oil pulling as a supplementary practice, use coconut or sesame oil, but understand it should complement rather than replace standard oral hygiene and professional dental treatment, as supported by the general principles of oral health outlined in 1.

From the Research

Effectiveness of Oil Pulling in Preventing Dental Caries

• Oil pulling is a traditional practice that has been claimed to have various health benefits, including the prevention of dental caries 2.
• A study published in 2019 found limited but consistent evidence to support the use of oil pulling for the prevention of dental caries, particularly when using coconut oil 3.
• However, there is limited research on the effectiveness of oil pulling in preventing dental caries compared to other methods such as pit and fissure sealants and fluoride varnishes 4, 5, 6.

Comparison with Other Methods

• Pit and fissure sealants have been shown to be more effective than fluoride varnishes in preventing occlusal decays of first molars in children and adolescents 4, 6.
• Fluoride varnishes have been found to be effective in preventing dental caries and are safe for use in young children 5.
• The effectiveness of oil pulling in comparison to these methods is not well established, and more research is needed to determine its efficacy in preventing dental caries.

Current Evidence and Limitations

• The current evidence on oil pulling is limited, and more studies are needed to confirm its effectiveness in preventing dental caries 3.
• The studies that have been conducted on oil pulling have methodological limitations, and further research is needed to establish its efficacy and safety 2, 3.
