Brush occasionally with baking soda paste

Mix baking soda with water to form a paste and brush gently 1-2 times per week to remove surface stains. Baking soda is mildly abrasive, which helps polish away extrinsic stains from foods and drinks without the cost of commercial products.

Steps

1. Mix 1 teaspoon of baking soda with enough water to form a thick paste.
2. Apply the paste to a soft-bristled toothbrush.
3. Brush gently for 1-2 minutes, focusing on visible stain areas.
4. Rinse your mouth thoroughly with water.

Tips

• Limit to 1-2 times per week -- overuse can wear down enamel over time
• This method removes surface stains only; it will not change the natural color of your teeth
• The ADA considers baking soda safe for teeth when used appropriately in toothpaste formulations
• For a ready-made option, look for toothpastes that already contain baking soda
