Crest 3d pro
Crest 3D White products are whitening products whose results depend on their peroxide formula, contact time, and existing tooth colour.
The short answer
Crest 3D White is a range of whitening products, including toothpastes and strips, rather than one single treatment. A toothpaste mainly removes surface stain, while a peroxide-containing strip can lighten some internal tooth discolouration.
How do surface stains form on the enamel pellicle?
Surface stains sit on the enamel pellicle and can be reduced by brushing. Peroxide whitening works by oxidising colour molecules within enamel and dentine, but fillings, crowns, and veneers do not whiten in the same way.
How should the exact whitening product be used?
Read the exact product directions and use only the stated amount and contact time. Stop if marked sensitivity or gum irritation develops, and have untreated decay, leaking restorations, or gum inflammation assessed before whitening.
When does a colour change need a dentist’s examination?
See a dentist for one dark tooth, unexplained colour change, pain, or sensitivity that continues after stopping the product. A dental examination can distinguish stain, decay, trauma, and natural variation.
Which formulation suits your teeth, gums, and restorations?
Ask which Crest formulation you have, whether its ingredients suit your teeth and gums, and whether existing restorations will need colour matching after whitening.
Frequently asked questions
Can whitening toothpaste change the natural tooth colour?
It mainly removes external stain and does not replace professional assessment of deeper discolouration.
Why do teeth feel sensitive?
Peroxide can temporarily irritate dentine pathways; persistent or severe sensitivity warrants review.
