Amid ongoing conflict in the Middle East, several U.S. cities, particularly Baltimore, are facing significant shortages of fluoride for drinking water. This crisis has prompted authorities like the Baltimore Department of Public Works to reduce fluoride levels to cope with supply chain disruptions. The situation has raised concerns among dental professionals about the potential impact on public health. Water utilities across the country are now grappling with the effects of these supply challenges, linked to the ongoing war in Iran, further complicating the provision of safe drinking water.
