Does charcoal toothpaste whiten teeth?

Not in any lasting way. Charcoal is abrasive, so it can scrub off some surface stains and make teeth look brighter briefly, but it does not change the underlying colour and can wear down enamel over time. For real, safe whitening, a professional treatment is a better choice.

Is oil pulling worth doing?

There is little reliable evidence that swishing oil does anything brushing and flossing do not do better. It is unlikely to harm you as an extra, but it is no substitute for the basics — and it will not treat decay or gum disease if either has already started.

Is sparkling water bad for my teeth?

Plain sparkling water is mildly acidic but far gentler on teeth than soft drinks or flavoured, sweetened versions. Enjoyed with meals it is generally fine. The bigger risk comes from sugary and citrus-flavoured varieties sipped slowly throughout the day.

Does sugar-free gum actually help?

Yes, in a modest way. Chewing sugar-free gum after meals boosts saliva, which helps rinse away food and neutralise acid. It is a useful top-up when you cannot brush, but it is an addition to brushing and flossing, not a replacement for them.
