Overview
- UK outlets, which published Tuesday, amplified a TikTok from hygienist @avalene.r naming apples, strawberries, celery and cheese as options for a brighter smile.
- Colgate says crunchy foods such as apples and celery boost saliva flow, which helps wash away food and protect tooth surfaces from decay.
- The company adds that firmer cheeses can rub off some surface stains and raise mouth pH, which may slow the processes that lead to cavities.
- Coverage cites a Clinical Oral Investigations paper reporting that bromelain, an enzyme in pineapple, can help remove surface stains and plaque.
- Reporters present these tips as add-ons to brushing and flossing twice daily, and they urge limits on coffee, tea, red wine, berries, pasta sauces and curries that can stain teeth.
