The short answer
Level 9 whitening strips can lighten some surface and internal stains on natural teeth, but the visible result depends on the starting stain and the condition of the enamel.
What are peroxide whitening strips made to do?
These strips are thin flexible carriers coated with a peroxide whitening formulation. “Before and after” refers to a change in the colour of natural tooth structure, not a guaranteed change in crowns, fillings, bonding, or veneers.
How should you apply Level 9 strips correctly?
Read the product directions, clean and dry the teeth as directed, adapt the strip to the tooth surfaces, and remove it at the stated time. Stop if marked burning, persistent pain, or significant gum peeling occurs.
When should a dentist check your teeth before whitening?
See a dentist before using strips over untreated decay, enamel defects, gum recession, or existing sensitivity. A dental review is also appropriate when one tooth is darker, because trauma or loss of pulpal vitality may be involved.
Will whitening affect restorations or suit your tooth colour?
Ask whether the discoloration is on natural enamel, whether restorations will match afterward, and whether an examination or professional whitening is more suitable for your teeth.
Frequently asked questions
Can home care replace a dental examination?
Home care may ease a symptom, but it cannot identify or correct decay, infection, gum disease, a crack, or a failing restoration.
What changes make this more urgent?
Rapid worsening, swelling, fever, heavy bleeding, severe pain, or difficulty swallowing or breathing calls for prompt dental or emergency assessment.
