Fluoride vs hydroxyapatite isn't a fight — fluoride hardens the enamel surface against cavities, while hydroxyapatite (the mineral enamel is made of) rebuilds a smoother surface and calms sensitivity. Here's how they differ, and why the best toothpastes use both.

No toothpaste can regrow receding gums — but the right one firms the gum you still have, seals the exposed sensitive tooth necks with hydroxyapatite, and helps slow further recession. Here's how to choose between LACALUT SENSITIVE and AKTIV, and how to brush.

Sensitive-teeth toothpastes work in one of two ways — sealing the exposed tubules or soothing the nerve. Here's how the two families differ, and which suits you.

Hydroxyapatite is the mineral your enamel is made of — a toothpaste that contains it rebuilds the worn surface and brightens teeth gently, without giving up fluoride. Here's how it works and what to look for in Australia.

Enamel does NOT grow back — it has no living cells, so once it is physically gone it is gone forever. But enamel loses and regains mineral every day, and you can tip that balance: you can re-harden softened enamel and reverse an early white-spot lesion, even though you can never remineralise a cavity.
