How to prevent & treat tooth discoloration?

To prevent tooth discoloration, maintain good oral hygiene by brushing and flossing regularly, and limit the consumption of staining foods and beverages like coffee, tea, and red wine. Regular dental check-ups and professional cleanings can also help. For treatment, options include whitening toothpaste, over-the-counter whitening products, or professional whitening treatments performed by a dentist. Additionally, using a straw when drinking stain-causing beverages can reduce contact with teeth.
