Before after crest white strips
before after crest white strips is assessed by its symptoms, anatomy, timing, and examination findings.
The short answer
Age-related yellowing, certain foods and drinks, tobacco staining, fluorosis, trauma, and medication-related discolouration respond differently. A darker tooth may need investigation rather than repeated whitening.
What is the direct answer?
What does this question mean?
Use only as directed and avoid extending contact time to chase a lighter shade. Reduce irritants if sensitivity occurs and have cavities or gum problems treated first.
What can you do next?
Seek care for spontaneous tooth pain, a single dark tooth, enamel defects, gum burns, or sensitivity that persists after stopping the product.
When should you seek dental care?
Ask what type of stain is present, whether photographs can document the starting shade, and how existing restorations will affect the final colour.
What should you ask the dentist?
Ask which structure is involved, what examination supports the diagnosis, and which treatment options fit the finding.
