How does peroxide gel make stained teeth look lighter?
Whitening gel uses a peroxide compound that breaks down stain molecules within enamel and dentin, making teeth look lighter. The result depends on formulation, contact time, starting shade, and whether the colour is a surface stain or restoration.
What should a dentist check before you use whitening gel?
Have a dentist examine cavities, cracks, gum recession, and existing fillings, crowns, or veneers before whitening. Follow the prescribed application time, keep gel off the gums, and stop if marked sensitivity or soft-tissue irritation develops.
When should tooth pain or a dark tooth be assessed?
Seek dental care before whitening when a tooth hurts, has a visible cavity, reacts sharply to cold, or has a dark single-tooth colour change. Contact the clinician for persistent sensitivity, gum burns, or swelling.
Will whitening gel change the colour of fillings or crowns?
Will gel whiten fillings or crowns? No, peroxide changes natural tooth colour but does not change most tooth-coloured restorations. Why might whitening cause sensitivity? Peroxide can irritate exposed dentin or the pulp, especially when recession or defects are present.
