Is whitening your teeth harmful
Tooth whitening can cause temporary sensitivity or gum irritation when peroxide exposure or the treatment method is unsuitable.
The short answer
Whitening is usually a controlled chemical treatment, but peroxide can cause temporary sensitivity or gum irritation when the method or concentration is unsuitable.
What is the direct answer?
What does this question mean?
Tooth whitening uses hydrogen peroxide or carbamide peroxide to break down stain molecules in enamel and dentin. It does not change the colour of fillings, crowns, veneers, or dentures.
What can you do next?
Use a dental examination to check cavities, cracks, exposed root surfaces, gum inflammation, and existing restorations before whitening. Follow the prescribed contact time and stop if sharp sensitivity or a chemical burn develops.
When should you seek dental care?
Arrange dental care promptly for persistent pain, white or ulcerated gum patches, swelling, or sensitivity that continues after the whitening product is stopped.
What should you ask the dentist?
Ask which peroxide is being used, whether any decay or gum recession needs treatment first, and how existing fillings or crowns will look after the natural teeth change colour.
