How do teeth polishing and whitening produce different results?
Polishing removes deposits and surface stain, while whitening lightens tooth color with peroxide that acts inside enamel and dentin.
What can polishing change on the outer tooth surface?
Polishing cleans outer tooth surfaces with instruments or paste and does not change natural enamel shade. Whitening uses carbamide or hydrogen peroxide to oxidize colored molecules within enamel and dentin.
How can you identify the right treatment for discolouration?
A dentist identifies plaque, calculus, external stain, intrinsic discoloration, or a restoration before choosing scaling, polishing, or whitening.
When should persistent tooth colour changes be examined?
Have an examination for persistent discoloration, sensitivity, gum inflammation, cavities, or visible restorations.
What should you ask about stains, cleaning, and restorations?
Ask whether the stain is superficial or internal, whether cleaning comes first, and how fillings or crowns affect the result.
