5. Cut Down on Staining Foods
If you don’t like the way stained teeth affect your appearance, teeth whitening can help, but the results don’t last as long if you’re consuming a lot of staining foods and beverages. Some of the worst culprits are chocolate, coffee, tea, cokes, red wine, dark beer, and berries. That’s a lot of good stuff and it’s hard to cut them out, but just a little bit of reduction can make a difference. Still can’t do it? Try a resolution to use a straw with cold staining beverages.
