Overuse can damage tooth enamel.
• Bicarbonate does not change the internal color of the tooth, it only removes surface stains.
• It is recommended to use it a maximum of once a week.
b) Garlic
Garlic, on the other hand, is less well-known for teeth whitening. Its properties are primarily antibacterial and antifungal. Thanks to the allicin it contains, it fights the bacteria responsible for bad breath, oral infections, and cavities.
However, no serious scientific study proves that garlic has a teeth-whitening effect.
The combination of these two ingredients could, at best, contribute to better oral health, but it is highly unlikely to make teeth as white as the photos show in just 2 minutes. "Before/after" images are often retouched or exaggerated to attract attention.
3. Natural methods that can help
While garlic and baking soda are not a miracle cure, there are natural remedies that, when used correctly, can improve tooth whiteness:
• Baking soda: as explained, in moderate use, it helps to remove superficial stains.
• Coconut oil pulling: rinsing your mouth with a spoonful of coconut oil for 10 to 15 minutes can reduce bacteria and give a brighter smile.
• Activated charcoal: used as a brushing powder, it absorbs toxins and helps to polish teeth.
• Strawberries and lemon: these fruits contain malic acid and vitamin C which can help whiten teeth, but be careful not to overdo it, as their acidity can weaken the enamel.
• Good oral hygiene: brushing twice a day, flossing and regular visits to the dentist are the essential foundation.
