How to whiten yellow teeth
My husband is 28 years old this year, and his teeth are particularly yellow. It has become quite noticeable, and he hasn't taken care of it. He also doesn't like to brush his teeth regularly. I wonder what can be done to whiten yellow teeth?

Teeth can turn yellow due to various factors, including dietary habits such as drinking coffee, tea, or red wine, tobacco use, natural aging leading to enamel wear, and the effects of certain diseases or medications. The following are some methods to improve tooth color:
1. Teeth whitening products: Various over-the-counter teeth whitening products are available, such as toothpaste containing hydrogen peroxide or whitening strips, although effectiveness varies among individuals and they may cause sensitivity.
2. Professional whitening: Whitening services provided by dentists, such as in-office laser whitening or customized home whitening trays, often yield more noticeable results, but may require multiple treatments.
3. Dental cleaning: Regular professional dental cleanings can help remove surface stains and improve the appearance of teeth.
If teeth continue to yellow or if other oral problems arise, medical advice should be sought promptly.
