Crest white strips before and after 10 days
After ten days of whitening strips, natural teeth may look lighter, but results vary with the stain, instructions, enamel, and restorations.
The short answer
Ten days can lighten natural tooth colour, but strips cannot change fillings, crowns, veneers, or caps and may cause sensitivity.
What is the direct answer?
What does this question mean?
Strips carry peroxide gel against enamel; peroxide breaks down coloured molecules without removing enamel.
What can you do next?
Follow the labelled wear schedule, keep gel off gums, compare shade in consistent lighting, and pause if irritation develops.
When should you seek dental care?
Seek care for persistent pain, gum ulcers, a single dark tooth, or uneven colour that remains after the course.
What should you ask the dentist?
Ask whether stains are surface or internal, whether restorations will mismatch, and what schedule limits sensitivity.
Frequently asked questions
What is the first practical step?
Record the symptom and trigger, keep the area clean, and arrange a focused dental assessment.
Can I treat the cause from the symptom alone?
No. Similar sensations can come from different tissues, so diagnosis guides treatment.
