What stains your teeth enamel?

Over time, pigmented residue from food and beverages builds up and is absorbed by the enamel, creating a stain. While coffee and cola are common tooth-staining culprits, any food or beverage with dark tannins can cause tooth discoloration, including dark berries, fruit juices, and tomato-based sauces. Chemical compounds called chromogens give certain foods and drinks their strong color, and these compounds can stain our teeth. Foods and drinks containing a substance called tannin can also cause staining. Acids can wear down your teeth, increasing the chance they get stained. Intrinsic stains cannot be removed, but they can be covered up with cosmetic options. Extrinsic stains can usually be removed with whitening. Professional teeth whitening may be necessary for some deep, longstanding set-in stains.
