How to get false teeth white again
Dentures can be cleaned of deposits and stain, but acrylic artificial teeth cannot be whitened like natural enamel with bleaching gel.
The short answer
Dentures usually contain acrylic or resin teeth, which do not respond to natural-tooth whitening in the same way enamel does. Surface deposits may be removed, while permanently changed teeth may need polishing or replacement.
What causes stains and discolouration on dentures?
Tea, coffee, tobacco, pigments, plaque, and calculus can discolor a denture. Abrasive powders can scratch acrylic and make deposits cling more readily.
How should you brush stained dentures at home?
Remove the denture and brush it with a soft denture brush and non-abrasive cleanser. Avoid boiling water, bleach, abrasive toothpaste, and acids.
When should persistent denture staining be assessed?
Arrange review when stain remains, the denture smells, loses fit, cracks, or causes sore spots. A laboratory can assess embedded discoloration and damaged resin.
Can polishing or replacement restore your denture colour?
Ask whether professional polishing can remove the stain or whether artificial teeth, the base, or the whole denture needs replacement.
