Crest before after
Before-and-after tooth changes depend on the exact Crest product, the starting stain, and whether the colour change is surface stain or internal discolour.
The short answer
Crest is a product brand with several oral-care formulations, including toothpastes and whitening products. A before-and-after comparison is meaningful only when the same teeth, lighting, shade conditions, and time interval are used.
Which tooth structures can explain a colour change?
This describes the anatomy and mechanism involved, including the tissues or material that can explain the finding.
What can you do now about the colour difference?
Keep the area clean, avoid aggravating triggers, and arrange an examination so the clinician can inspect, test, and image it when indicated.
When does a colour change need prompt dental care?
Seek prompt care for persistent or worsening symptoms, and urgent assessment for facial swelling, fever, or difficulty swallowing or breathing.
What should the dentist examine before treatment?
Ask what structure is affected, which examination or image is needed, and which treatment addresses the cause.
Frequently asked questions
Can home care replace an examination?
Home care may ease irritation, but the underlying cause determines whether dental treatment is needed.
What should I mention at the visit?
Describe when it began, where it occurs, its triggers, duration, and any recent dental work or injury.
