What is the direct answer?
Whitening gel risks depend on peroxide formulation, contact time, application, tooth condition, and following directions.
What could it mean?
Whitening gel can cause sensitivity or gum irritation, and suitability depends on the health of teeth and gingiva.
What can you do next?
Hydrogen peroxide or carbamide peroxide oxidizes color molecules; fillings, crowns, and veneers do not whiten.
When should you seek care?
Have teeth examined first, keep gel off gingiva, follow instructions, and stop for marked pain, ulceration, or swelling.
Questions to ask the dentist
Arrange assessment for decay, cracks, exposed roots, inflamed gums, or severe pain after whitening.
FAQ
