Discoloured teeth can result from: Extrinsic stains – surface stains that develop on the outside of the teeth. These can typically be removed through professional scaling and polishing. Intrinsic stains – stains that form within the tooth structure itself. These cannot be removed by scaling and polishing, though some may be lightened with bleaching treatments. Discoloured Teeth – Signs and Symptoms While extrinsic stains are primarily a cosmetic concern and don’t usually cause discomfort, intrinsic discoloration especially when inherited or present from birth may be linked to underlying dental issues. These can include signs such as tooth sensitivity, persistent toothache, and visible cavities or pits in the enamel, which may indicate tooth decay. Discoloured Teeth – Common Causes and Contributing Factors Dark food and drinks – Frequent consumption of items like coffee, tea, red wine, soda, or richly spiced foods can stain enamel. Developmental disruptions – Medications like tetracycline or high fluoride intake during early tooth development may lead to internal staining. Health conditions during childhood – Illnesses such as prolonged high fever or metabolic imbalances can interfere with enamel and dentin formation. Genetics – Some people naturally have enamel that is more susceptible to discolouration. Aging process – As enamel wears down over time, the yellowish dentin underneath becomes more visible. Inadequate oral care – Irregular brushing and flossing allow plaque and stains to build up. Discoloured Teeth – Treatment Options In many cases, professional teeth whitening can significantly enhance the brightness of your smile by lightening stained or discoloured teeth. For teeth that do not respond well to whitening, cosmetic solutions like dental veneers or crowns may be recommended to restore a natural, uniform appearance.
