## Primary text

Your tooth enamel is about 97% one mineral. It's called hydroxyapatite.

Now pick up your toothpaste and read the ingredients. A detergent for the foam. A hard mint for the "clean" feeling. An abrasive for the instant smooth. The actual mineral? Not in the tube.

Dr.Strongbite is a paste built around that mineral instead — nano-hydroxyapatite, plus calcium, bicarbonate of soda and coconut oil. Ingredients you can pronounce, zero foam theatre.

**Creative:** Split frame — a magnified enamel-white brick wall texture on one side, the ingredient list of a generic tube (blurred brand) on the other. Or: hands turning a tube over to read the back.

**Notes:** The workhorse angle. Everything in it is Tier-1 composition fact.
