Is an ARC whitening pen safe for your teeth?
A whitening pen’s risks depend on its peroxide formula, concentration, contact time, application accuracy, and your dental condition.
What can a whitening pen change on your teeth?
A whitening pen applies bleaching gel to tooth surfaces; it cannot change the colour of fillings, crowns, veneers, or bonding.
How can you use a whitening pen more safely?
Keep gel off the gums, follow the label, and stop for marked burning, ulcers, or persistent pain. Have decay, cracks, recession, and gum inflammation assessed before use.
When should you seek advice before whitening?
Arrange dental advice before use if you have pain, untreated decay, gum disease, exposed roots, ulcers, or restorations. Seek prompt care for severe or persistent irritation.
What should you ask about whitening pen treatment?
Ask about the active ingredient, concentration, gum and tooth findings, restoration colour, and supervised alternatives.
