A Closer Look at what Causes Stains
- Foods—many common foods and condiments, including tomato sauce, red and white wine, mustard, berries, tea, coffee, and soda cause stains over time.
- Meds and Supplements—children 8 and younger can develop stains as tetracycline (an antibiotic) bonds to calcium in developing teeth. Ingesting large amounts of fluoride can result in brown dental stains.
- Nicotine—when nicotine combines with oxygen, it turns yellow. Over the years, nicotine can stain enamel and the outer layers of dentin.
- Genetics—some of us are born with darker teeth, while others are born with weak enamel that can stain easily.
