If you’re checking the viral “Lemon Juice and Colgate: The Sour Trick That Scrubs Away Stains Fast” claim, I would not recommend it for teeth.
🍋 Why the trick is risky
Lemon juice is highly acidic. Acid can soften and permanently erode tooth enamel. Adding toothpaste doesn’t neutralize that risk; rubbing toothpaste against acid-softened enamel can potentially increase wear. The American Dental Association specifically warns that acidic foods and fruit juices can contribute to dental erosion.
It may appear to whiten teeth temporarily by removing some surface discoloration, but that’s not the same as safely whitening the teeth. As enamel becomes thinner, the underlying yellowish dentin can actually become more visible, making teeth look yellower.
🦷 Safer approach
- Brush twice daily with fluoride toothpaste and use a soft-bristled toothbrush.
- For whitening, use a tested whitening product according to its directions or ask a dentist about professional whitening.
- If you’ve consumed lemon or another acidic food/drink, rinse with water and don’t brush immediately. The ADA recommends waiting before brushing so saliva has time to help the enamel recover.
