Researchers at the University of Nottingham in the UK have developed a groundbreaking protein-based gel that leverages calcium and phosphate ions, naturally abundant in human saliva, to repair and regenerate damaged tooth enamel.
This innovation, detailed in a study published in Nature Communications, represents a potential shift away from traditional "drill and fill" dentistry toward true enamel restoration.
The gel mimics the natural proteins that guide enamel formation during infancy. When applied to teeth, it forms a thin, robust layer that seeps into cracks and eroded areas.
Acting as a scaffold, it attracts and organizes calcium and phosphate from saliva (or even donated saliva samples), promoting "epitaxial mineralization"—a process where new enamel crystals grow in perfect alignment with the existing tooth structure, restoring its hardness and architecture.
Lab tests showed the regenerated enamel withstands real-world stresses like brushing, chewing, and acidic exposure (e.g., soda) as well as—or better than—natural enamel. It remained intact for weeks in simulated oral environments.

@CityNewsWPG That chief that he been given tax dollars to himself and not helping "his people" He could've gave more money to the hospital for his VIP treatment 🙄
@JackBen18694530@MichelleLA1981 I don't support the mass illegal immigration glad the fake letters of acceptence that the indians use are back home. There are some back home most Canadians doesn't Canada want it to look like Neo-india
Mark Carney is the biggest loser Canadians have ever elected. He couldn't even send a delegate to the US for talks. He does not care about Canada. He's here to make himself and his friends rich off your hard earned money and tax dollars.
The Guy on the LEFT provided a better economy than the guy on the RIGHT.
The guy on the LEFT doesn’t know how to do Basic math and think he is saving the planet by drinking water out of paper boxes.
