9. Avoid Stain-Causing Foods and Drinks
Coffee, tea, red wine, and sodas are the biggest culprits behind yellow teeth.
Hack: If you can’t give them up, use a straw to minimize contact with your teeth, and rinse your mouth with water immediately afterward.
10. Rinse with Salt Water
Saltwater is a natural disinfectant that helps reduce bacteria and brighten your smile.
How to use: Mix half a teaspoon of sea salt in a glass of warm water. Use it as a mouth rinse once or twice daily.
