Persistent or unusual discoloration requires diagnosis before cleaning or whitening.", "sections": [ { "heading": "Clinical mechanism", "body": "The acquired pellicle is a protein-rich film on enamel. Chromogens and tannins from coffee and tea can bind to this film and plaque. Smoke from shisha contains particulate residues that can collect at the cervical enamel and exposed root surfaces. Intrinsic colour also reflects dentin beneath translucent enamel, so surface cleaning cannot correct every yellow or grey appearance." }, { "heading": "Clinical steps", "body": "A dental visit begins with examination of enamel, dentin, gingiva, restorations, and possible decay or pulpal disease. Plaque and calculus are removed with professional scaling and polishing when indicated. If natural teeth are suitable, whitening may use hydrogen peroxide or carbamide peroxide under dental guidance. Peroxide whitening lightens natural tooth structure, not fillings, crowns, veneers, or composite bonding." }, { "heading": "Home prevention", "body": "Limit prolonged sipping, follow pigmented or acidic drinks with water, and use a straw for suitable cold drinks.
