Key Takeaways
  1. Teeth can appear yellow because of poor oral hygiene, diet, smoking, genetics, illness, trauma, certain medications, and aging.
  2. To prevent a yellow appearance of your teeth, improve your oral hygiene by brushing your teeth as recommended (i.e. twice a day) and flossing once a day; avoid stain-causing foods, certain medications, and nicotine; and visit your dentist twice a year.
  3. Teeth whitening options include whitening toothpaste, floss, whitening kits, and professional teeth bleaching.
  4. You can't whiten dental work such as fillings, dental crowns, or veneers with teeth whitening treatments, as they are made of materials that don't react to bleaching agents. Instead, focus on maintaining their appearance through good oral hygiene, regular professional cleanings, and potentially replacing them if they become significantly stained or discolored.
