The short answer
Night whitening uses a dentist-fitted tray and a peroxide gel applied for a prescribed wear period, with results depending on the starting shade and type of stain.
What does night whitening involve clinically?
The clinical subject is supervised take-home tooth whitening, not a special whitening effect from sleeping. Carbamide peroxide or hydrogen peroxide releases oxygen that breaks down some organic stain molecules in enamel and dentine.
What should happen before you begin night whitening?
A dentist first checks cavities, cracked teeth, gum inflammation, restorations, and the cause of discoloration. If whitening is suitable, the dentist supplies a fitted tray and gives exact gel amount, wear time, storage, and stop instructions.
When should you stop whitening and contact the dental team?
Stop and contact the dental team for marked sensitivity, gum burning, ulceration, uneven colour, or pain from a particular tooth. Whitening should be assessed before use when teeth are decayed, gums bleed, or the colour change may be internal.
What should you ask about trays, gel and sensitivity?
Ask which peroxide concentration and tray design will be used, how long each application lasts, how restorations will appear, and what to do if sensitivity or gel leakage occurs.
Frequently asked questions
What determines the best next step?
Whitening changes natural tooth colour, not most restorations.
