How does whitening affect teeth and existing restorations?
Whitening breaks down colour molecules in enamel and dentine, while restorations keep their original shade.
What should you arrange before starting tooth whitening?
Ask about stain type, existing fillings or crowns, sensitivity control, and the exact gel or tray schedule.
When should whitening wait until a dental problem is checked?
Whitening is a cosmetic option only after decay, gum disease, cracks, and unexplained darkening have been assessed.
What should you ask before choosing a whitening treatment?
Ask which finding explains the problem, what examination or imaging is needed, and which treatment options fit your teeth and gums. Discuss expected discomfort, maintenance, alternatives, and the signs that require a prompt review.
Frequently asked questions
Can home care replace an examination?
Home care can reduce irritation and plaque, but it cannot identify decay, infection, bone changes, or a failing restoration.
What information helps the dentist?
Describe when the symptom began, what triggers it, what relieves it, and any recent injury, dental work, or medication change.
