What is the direct answer?
To brighten a smile, first identify whether colour comes from surface stain, enamel, dentine, decay, or restorations.
What does this question mean?
Enamel and dentine influence natural colour, while surface pigments darken teeth. Whitening does not change fillings, crowns, veneers, or bonding in the same way.
What can you do next?
Begin with fluoride toothpaste, interdental cleaning, and professional removal of hardened deposits. Options may then include polishing, whitening, decay treatment, or restoration matching.
When should you seek dental care?
Arrange an examination before whitening if teeth are painful, cracked, decayed, worn, or sensitive; sudden darkening of one tooth needs prompt assessment.
What should you ask the dentist?
Ask what causes the colour difference, whether whitening affects every visible tooth, and how sensitivity and restoration matching will be managed.
