Here are 5 easy homemade hacks to whiten yellow teeth:

Baking Soda and Lemon Juice
Mix a small amount of baking soda with lemon juice to create a paste. The mild abrasiveness of baking soda, combined with the acidity of lemon, can help remove surface stains. Brush with it once a week.

Strawberry and Baking Soda Paste
Mash a ripe strawberry and mix it with baking soda. The malic acid in strawberries helps break down plaque, and the baking soda acts as a mild abrasive. Apply this mixture for a few minutes before rinsing off.

Coconut Oil Pulling
Swish a tablespoon of coconut oil in your mouth for 10-15 minutes daily. This helps to remove bacteria and plaque, preventing yellowing.

Apple Cider Vinegar Rinse
Dilute apple cider vinegar with water and swish it around your mouth. Its acidic nature helps remove stains, but used in moderation to avoid enamel damage.

Activated Charcoal
Gently brush with activated charcoal, which can absorb toxins and surface stains. Use it sparingly to prevent damage to tooth enamel.
