Crest pro health 3d whitening
Crest 3D whitening products use peroxide or whitening abrasives depending on the product, so check the exact formulation and directions.
The short answer
Crest 3D whitening is a product range, not one treatment; the ingredients and whitening effect depend on whether you are using strips, toothpaste, or another formulation. Follow the label and do not combine whitening products without professional advice.
How do strips and toothpaste whiten teeth differently?
Whitening strips generally hold peroxide gel against enamel, while whitening toothpastes mainly remove surface stains with cleaning ingredients and mild abrasives. Neither approach changes the colour of fillings, crowns, veneers, or implants.
What should you check before starting Crest whitening?
Identify the exact product, read its active ingredients and directions, and use only the stated contact time. A dentist can inspect enamel, cavities, gum margins, and restorations before you begin and can offer custom trays when a controlled fit is needed.
When should you avoid whitening and see a dentist?
Arrange an examination if you have pain, cavities, gum irritation, exposed roots, or strong sensitivity before whitening. Stop use and seek advice for persistent sensitivity or gel-related gum soreness.
What should you ask about whitening and dental restorations?
Ask which product type matches your stain, whether peroxide can reach every visible tooth evenly, and how existing dental work will look afterward. Ask for a sensitivity plan and an alternative if the colour change is inside the tooth.
Frequently asked questions
Can whitening toothpaste replace professional whitening?
It may remove some surface staining, but it does not provide the same treatment as professionally planned peroxide whitening.
Why are my gums sore after strips?
Gel may have contacted the gum or the strip may not have fitted the tooth shape; stop use and ask a dentist to check the tissue.
