Which dental restorations will not change colour?
Whitening changes stains within enamel and dentin; it does not change the colour of fillings, crowns, veneers, or implants. Results depend on the original stain and on which parts of the smile are natural teeth.
What should your dentist check before whitening?
A dentist first examines for decay, cracked enamel, gum inflammation, and exposed dentine. During treatment, a fitted barrier protects the gingiva, the gel is applied and timed, and the teeth are rinsed and checked; follow the practice instructions for sensitivity afterward.
When should tooth whitening be delayed for care?
Seek an examination before whitening if you have toothache, untreated cavities, gum disease, or marked sensitivity. Contact the practice if pain is severe, persists, or is accompanied by gum irritation after treatment.
What should you ask about stains and restorations?
Ask which stains are likely to respond, whether restorations will remain a different shade, and which protocol suits your enamel and sensitivity history. Ask how the clinician will protect your gums and what to do if sensitivity develops.
Frequently asked questions
Does Philips Zoom whiten fillings?
No. Restorations keep their existing shade, so matching may be discussed after natural teeth are whitened.
Why can whitening cause sensitivity?
Peroxide can temporarily irritate dentine pathways or the pulp in susceptible teeth; the dentist can adjust the protocol.
