Today I noticed my brother's teeth are particularly yellow and unattractive. I'm worried he might have trouble finding a girlfriend, so I'd like to ask—what can be done to whiten yellow teeth?

Yellow teeth can be whitened through dental cleaning, but cleaning typically only removes surface stains or pigmentation. For more thorough whitening, professional dental clinics often offer cold light whitening treatments. This method can effectively whiten teeth, but may cause some damage to the tooth structure, as it often involves tooth polishing.
