Philips sonicare whitening pen

A whitening pen marketed with a Philips Sonicare system usually applies a peroxide gel to natural teeth; it does not whiten crowns, fillings, or veneers.

A whitening pen is a small applicator containing a whitening formulation. The brush removes plaque, while the pen places gel on tooth surfaces; these are separate actions and the product name does not establish the ingredient or treatment strength.

Read the active ingredients and instructions, check the product seal and expiry, and have sensitive teeth, cavities, gum recession, or restorations assessed before use. Apply gel only as directed and keep it off the gums and oral lining.

Seek dental advice before using whitening gel on painful or damaged teeth. Stop and seek review for persistent sensitivity, ulceration, gum irritation, or a colour mismatch involving restorations.

Ask what peroxide is present, which surfaces may be treated, how restorations will appear afterward, and whether your teeth and gums need examination first.
