Dental question about taxonomy:symptom:yellow-teeth
Yellow teeth may reflect natural dentin colour, surface stain, calculus, or changes within the tooth.
The short answer
Yellow teeth can reflect the natural colour of dentin showing through translucent enamel, surface stain, plaque, calculus, or changes within the tooth. The right approach depends on whether the colour is on the surface or comes from the tooth structure.
What is the direct answer?
What does this question mean?
Enamel is the pale outer layer of a tooth, while dentin beneath it is naturally more yellow. Tea, coffee, tobacco, plaque, calculus, ageing, enamel thinning, decay, trauma, and some medicines can change the appearance of one or many teeth.
What can you do next?
Brush twice daily with fluoride toothpaste, clean between teeth, and arrange a professional examination before whitening. A hygienist can remove calculus and external stain, while a dentist can assess decay, erosion, cracks, restorations, or internal discolouration that whitening will not correct.
When should you seek dental care?
See a dentist if one tooth becomes yellow or grey, the colour change is sudden, or it comes with pain, sensitivity, a hole, bad taste, or gum swelling. Children with unusual tooth colour should also be assessed rather than treated with a whitening product at home.
What should you ask the dentist?
Ask whether the colour is surface stain, enamel, dentin, or internal discolouration, and whether cleaning or whitening will change it. Ask how fillings, crowns, or veneers will compare in colour if cosmetic treatment is considered.
