What is the direct answer?
Zoom whitening can lighten natural teeth, but the visible result depends on the starting shade, stain type, enamel, and existing restorations.
What does this question mean?
Before-and-after images compare tooth colour before treatment with colour after the whitening session and any prescribed home phase. They are not a guarantee for every patient because yellow, brown, grey, internal, and restoration-related discoloration respond differently.
What can you do next?
Have the teeth, gums, cavities, cracks, and restorations examined before whitening, then discuss the target shade and whether a take-home tray is needed. Follow the clinician's wear instructions and limit strongly staining foods and drinks while sensitivity settles.
When should you seek dental care?
Seek care before cosmetic whitening if a tooth is painful, dark after an injury, fractured, decayed, or sensitive without a clear trigger. Contact the clinic if gel causes marked gum burning, blistering, or sensitivity that does not settle after the planned course.
What should you ask the dentist?
Ask what type of discoloration you have, whether Zoom treatment can affect it, and how crowns, veneers, or fillings will look afterward. Ask how the gums and dentine will be protected and what maintenance plan suits your shade goal.
Frequently asked questions
Will the result match my veneers?
Not automatically; restorations keep their shade and may need a separate shade plan.
Why can whitening feel sensitive?
Peroxide can temporarily stimulate fluid movement in dentine tubules, especially where enamel is thin or roots are exposed.
