What should I do if my teeth are a bit yellow?

1. If teeth become yellow due to aging, regular dental cleaning can help improve their appearance. 2. If poor dietary habits are the cause, reduce consumption of foods and drinks with strong pigments, such as coffee, tea, and red wine. 3. If inadequate oral care is the issue, improve brushing habits by using specialized whitening toothpaste and toothbrushes. 4. Visit a dentist. Dental professionals can provide more advanced, personalized treatments based on individual conditions. 5. Brush teeth morning and night, use dental floss to clean between teeth, have regular dental cleanings, and avoid smoking.
