Lemon juice is sometimes presented as a natural way to brighten a smile. Its sharp taste and a temporary clean feeling do not mean that it whitens safely. Acid can temporarily soften the enamel surface, while brushing immediately afterwards may increase the risk of damage.
Why can lemon create the illusion of whitening?
Acid affects the tooth surface but is not a controlled whitening method. Repeatedly rubbing lemon on teeth may contribute to sensitivity, dull enamel and greater susceptibility to staining.
Do not combine lemon with baking soda
This popular mixture combines two unfavourable mechanisms: acid-softened surfaces and mechanical abrasion. Do not apply it to teeth.
What should you do after acidic food or drink?
- Rinse your mouth with water.
- Do not scrub your teeth immediately.
- Return to normal hygiene after a suitable interval.
- Do not try to neutralise acid with another homemade ingredient.
What can you use instead?
For surface deposits, choose a product designed for oral use, such as Elixio Activated Charcoal Whitening Toothpaste. It targets surface stains rather than changing the natural colour of dentine.
