Can mustard oil, salt, and turmeric prevent all dental diseases?

The claim that mustard oil, salt, and turmeric prevent all dental diseases is false. While they have some antibacterial properties, they lack fluoride, crucial for cavity prevention. Cleaning with a finger is not effective and may harm enamel. Experts recommend brushing twice daily with fluoride toothpaste, flossing, and regular dental check-ups for proper oral health.
