What is the direct answer?
Blancone whitening is a branded system whose result and risks depend on its peroxide formula, contact time, tray fit, and dental condition.
What does this question mean?
Whitening gels use peroxide chemistry to break down some colored molecules in natural enamel and dentine. Most restorations do not change shade with the natural teeth.
What can you do next?
Sensitivity and gum irritation depend on concentration, application, enamel defects, exposed roots, decay, and tray fit.
When should you seek dental care?
Follow the label, keep gel away from the gum margin, and have untreated decay, cracks, gum disease, or a dark non-vital tooth assessed first.
What should you ask the dentist?
Ask which active ingredient and concentration are present and whether your restorations will match afterward.
Frequently asked questions
Is branded whitening right for everyone?
Suitability depends on the teeth, gums, formulation, and use. An examination identifies problems first.
Why are teeth sensitive afterward?
Peroxide can temporarily increase fluid movement through dentinal tubules, especially when dentine is exposed.
