What is Philips whitening gel intended to change?
Philips whitening gel is a peroxide gel intended to lighten some natural tooth discolouration when used in its prescribed tray or clinical system.
Peroxide can diffuse through enamel and dentine and alter some stain molecules. It cannot change ceramic, composite, metal, crowns, or veneers.
How does peroxide alter tooth stain molecules?
Peroxide can diffuse through enamel and dentine and alter some stain molecules. It cannot change ceramic, composite, metal, crowns, or veneers.
How should you apply whitening gel safely?
Use only the supplied amount and contact time, keep gel away from the gingival margin, and do not combine products without dental advice.
When should gel-related symptoms be assessed?
Ask for an examination if whitening causes strong or prolonged sensitivity, gum irritation, or uneven colour.
Why does whitening not change the colour of fillings?
Why did the gel not whiten my filling? Restorations do not respond like natural enamel, so shade matching and restoration replacement may be planned after whitening.
