Yellow teeth can become white again through various dental treatments and oral care practices. The natural color of teeth varies from person to person, and factors like genetics, age, and lifestyle habits can cause teeth to become yellow or discolored over time. However, there are several effective methods to whiten teeth:

• Professional dental cleaning: Having your teeth professionally cleaned on a regular basis by a dental hygienist can help to improve the appearance of your teeth by removing plaque and surface stains.
• Treatments for teeth whitening: Using bleaching agents, dentists can carry out expert teeth whitening procedures. These procedures can dramatically whiten teeth and are more effective than over-the-counter alternatives.
• Products for teeth whitening that are available over-the-counter include toothpaste, strips, gels, and rinses that can help remove surface stains and make teeth whiter.
• Home remedies: For tooth whitening, some people have success using organic solutions like baking soda, hydrogen peroxide, or activated charcoal. These techniques can have hazards if not utilised properly and could not be as efficient as professional treatments.
• Maintain good oral hygiene: Regular brushing, flossing, and using mouthwash can prevent new stains from forming and keep your teeth looking cleaner and whiter.

It's essential to consult with a dentist before starting any whitening treatment, especially if you have dental restorations like crowns or veneers, as they may not respond to whitening agents in the same way as natural teeth. Also, keep in mind that excessive use of whitening products can lead to tooth sensitivity or damage the enamel, so it's best to follow the dentist's recommendations for safe and effective teeth whitening.
