Crest 3d professional effects
Crest 3D White Professional Effects uses peroxide whitening strips to reduce some discoloration on natural teeth.
The short answer
Crest 3D White Professional Effects is an adhesive home-whitening strip product that uses a peroxide whitening ingredient to reduce some surface and internal tooth discoloration.
What determines the result from peroxide whitening strips?
Results depend on the original cause of discoloration, contact with the tooth, product instructions, and whether the tooth has a filling, crown, or veneer. Restorations do not respond like natural teeth, so shade mismatch can become more visible.
How should you apply these whitening strips safely?
Read the product directions, apply strips only to the intended teeth, keep gel away from the gum margin, and do not combine several whitening products without professional advice. Stop if burning, ulceration, or significant sensitivity occurs.
When should you have a dental examination before whitening?
Have a dental examination first when you have decay, gum disease, cracks, exposed roots, or a single dark tooth. Seek care for persistent pain, swelling, or a sore that does not settle after stopping the product.
Is your discolouration suitable for peroxide whitening?
Ask whether the discoloration is suitable for peroxide whitening, whether existing restorations affect the plan, and how to manage sensitivity or gum contact.
