Baking Soda - I already listed this as a key natural beauty must-have. Baking soda also naturally lightens stains on teeth! Just dip your toothbrush in some baking soda and brush like you normally would. **Warning: Don’t do this more than once a week because you can damage your enamel with too much scrubbing.
Celery, Apples & Carrots - All three are high in cellulose so they act like natural abrasives. They cleanse teeth and remove surface stains.
Spinach, Broccoli & Lettuce – Greens like these contain mineral compounds that form a film over the teeth. This film stops pigments of other foods from staining teeth.
