From the Guidelines
Oil pulling is not a reliable method for tooth whitening. While some people claim it helps whiten teeth by removing surface stains, there is insufficient scientific evidence to support its effectiveness for this purpose. The most recent and highest quality studies do not specifically address oil pulling for tooth whitening, and instead focus on proven methods of preventing dental caries, such as frequent exposure to small amounts of fluoride 1. Oil pulling involves swishing oil (typically coconut, sesame, or sunflower oil) in your mouth for 15-20 minutes before spitting it out. Though it may help reduce bacteria and improve oral hygiene to some extent, traditional whitening methods are more effective. For noticeable tooth whitening, consider using over-the-counter products containing hydrogen peroxide or carbamide peroxide (like whitening strips or gels), professional dental whitening treatments, or whitening toothpastes with mild abrasives. These work by either bleaching the teeth or physically removing surface stains. Some key points to consider when evaluating tooth whitening methods include:
- The effectiveness of the method in removing surface stains and bleaching the teeth
- The potential risks and side effects, such as tooth sensitivity or gum irritation
- The importance of combining any whitening method with regular brushing, flossing, and dental check-ups to maintain good oral health. If you still want to try oil pulling, use 1 tablespoon of oil daily, but understand it works primarily by reducing plaque rather than directly whitening teeth. For best oral health, prioritize proven methods of preventing dental caries, such as using fluoride toothpaste twice daily 1.
From the Research
Effectiveness of Oil Pulling for Tooth Whitening
- There is limited evidence to suggest that oil pulling is effective for tooth whitening.
- A study published in 2020 2 found that oil pulling with coconut oil may have a beneficial effect on improving oral health and dental hygiene, but the evidence was insufficient for conclusive findings.
- Another study published in 2023 3 compared the effectiveness of a hydrogen peroxide whitening strip to a regimen containing plant-based oils and Dead Sea salt, and found that the hydrogen peroxide strip was more effective in whitening teeth.
- A meta-analysis published in 2022 4 found that oil pulling may have a beneficial effect on reducing salivary bacterial colony count, but there was no significant difference in plaque index and gingival index score between the oil pulling and control groups.
- A review published in 2017 5 discussed the potential benefits of oil pulling for oral health, but did not provide conclusive evidence for its effectiveness in tooth whitening.
- A study published in 2014 6 discussed the safety and efficacy of tooth whitening regimens, but did not mention oil pulling as a method for tooth whitening.
Comparison to Other Whitening Methods
- Hydrogen peroxide-based whitening methods, such as whitening strips, have been shown to be safe and effective for tooth whitening when used according to manufacturer's instructions 6, 3.
- The effectiveness of oil pulling for tooth whitening is not well established, and more research is needed to determine its potential benefits and limitations 2, 4.
