Whitening toothpaste product selection and expectations
Whitening toothpaste mainly removes surface stains with cleaning ingredients, so it can brighten stained enamel but cannot change the natural colour of.
The short answer
Whitening toothpaste mainly removes surface stains with cleaning ingredients, so it can brighten stained enamel but cannot change the natural colour of fillings, crowns, veneers, or deeply discoloured teeth.
How do whitening toothpaste ingredients affect surface stains?
Most whitening toothpastes work through mild abrasives and surfactants; some also contain ingredients intended to reduce stain attachment. They do not bleach through enamel in the same way as professional peroxide whitening.
How should you use whitening toothpaste safely?
Brush twice daily with a soft brush and light pressure, and follow the product directions. If sensitivity or gum irritation appears, pause the product and use a toothpaste formulated for sensitivity while arranging advice if symptoms persist.
When should whitening be delayed for dental treatment?
See a dentist before whitening if you have decay, gum disease, enamel wear, exposed roots, or one dark tooth. An examination can identify whether cleaning, bleaching, restoration, or treatment of the tooth is appropriate.
What should you ask before choosing whitening toothpaste?
Is the colour change a surface stain or an internal change, what ingredient is in this product, and will my restorations match if natural teeth become lighter?
