How does a whitening pen place gel on your teeth?

A whitening pen uses a small brush or applicator to place gel on selected tooth surfaces. It cannot recolour fillings or crowns, and it may perform poorly when the stain lies inside enamel or dentin rather than on the surface.

What steps help you apply whitening gel safely?

Clean and dry the teeth as directed, paint a thin layer only on enamel, keep the gel away from the gums and lips, and allow the stated contact time. Do not use it on a painful, cracked, or untreated tooth without an examination.

When should you stop using a whitening pen and seek advice?

Stop and seek dental advice for burning gums, ulcers, significant sensitivity, or uneven darkening. A dentist can distinguish surface stain from decay, fluorosis, trauma-related colour change, or a dead pulp.

What should you ask about ingredients, restorations and gums?

Ask for the ingredient list, whether the product is suitable for your restorations and gum recession, and what alternative treatment fits the type of discoloration.
