Crest whitening emulsions before and after
Whitening emulsion results depend on the peroxide formula, contact time, starting shade, and whether the discolouration is in natural enamel or a restorat
The short answer
Whitening emulsion results depend on the peroxide formula, contact time, starting shade, and whether the discolouration is in natural enamel or a restoration.
How should before-and-after shade changes be compared?
Before-and-after changes are judged by comparing a recorded shade under consistent lighting. External stains from food or tobacco may respond differently from intrinsic colour within enamel or dentine, and a crown or filling keeps its original shade.
What should you check before using a whitening product?
Have teeth and gums examined before using a whitening product. Follow the label or dentist instructions, keep emulsion away from the gingival margin, and stop if burning or significant sensitivity develops.
Which whitening symptoms need prompt dental care?
Seek care for persistent burning, ulceration, severe sensitivity, a single dark tooth, or colour change after trauma. These findings can indicate a condition needing diagnosis.
What should you ask about emulsion results and restorations?
Ask whether the product contains peroxide, what stain type is present, how shade will be recorded, and whether restorations will need separate colour planning.

Whitening emulsion results depend on the peroxide formula, contact time, starting shade, and whether the discolouration is in natural enamel or a restoration.
Can home care replace dental treatment?
No. It can reduce symptoms or protect the area temporarily, but a dental examination is needed when the underlying cause may require treatment.
