From the foods you eat to habits such as smoking, many factors contribute to tooth discoloration.

The Cleveland Clinic suggests these preventive tips:

• Cut back on coffee.
• Quit smoking.
• Floss and brush your teeth regularly.
• See a dental hygienist twice each year.
• Visit your dentist if discoloration doesn’t ease after changing habits, or if you have other symptoms, such as bleeding gums.
