It Helps with Oral Hygiene
Tooth pain can bring down even the toughest survivor. But when toothpaste runs out, salt steps in. A saltwater rinse kills some bacteria and helps reduce gum inflammation. It can soothe sore gums, minor mouth injuries, and early tooth infections. Brushing with a mix of salt and baking soda is another trick. While it doesn’t replace a dentist, it helps slow decay and keep your mouth in check. Poor oral health can cause fevers, infections, or lost teeth—serious problems in a survival situation. Salt gives you a basic, effective way to care for your teeth when supplies are low.
