Foods That Stain
You should limit your intake of foods and beverages that are known to cause discoloration, such as wine, soda, tea, coffee, acidic drinks and berries. Another culprit — and a favorite food of many families — is tomato sauce of any kind, including pizza and spaghetti sauce.
Avoiding Tobacco Use
If you smoke or use smokeless tobacco, you should consider options to help you quit because tobacco stains your pearly whites and poses serious risks to the overall health of your body. Smokeless tobacco products, such as chewing or dipping tobacco, will stain your teeth even more because they come into physical contact with them. Moreover, smokeless tobacco can cause oral, esophageal and pancreatic cancer, according to the National Cancer Institute. Additionally, the American Cancer Society cites studies indicating that smoking tobacco can lead to lung cancer and other major health disorders.
Routine Dental Checkups
You should see your dentist every 6 months for a regular dental exam and a preventive cleaning appointment. This will help keep your mouth healthy, and the removal of plaque and other staining substances during the cleaning will also make your teeth look whiter.
