Does teeth whitening break down enamel
Whitening products are designed to change tooth color, but excessive concentration, contact time, or use on damaged teeth can irritate tissues and increase
The short answer
Whitening products are designed to change tooth color, but excessive concentration, contact time, or use on damaged teeth can irritate tissues and increase sensitivity.
What is the direct answer?
What does this question mean?
Peroxide gels diffuse through enamel and dentin and chemically break down colored molecules. Correctly selected whitening does not normally remove enamel, but defects, exposed dentin, leaking fillings, and overuse can make treatment painful or unsuitable.
What can you do next?
Have the teeth and gums examined before whitening, treat decay or gum inflammation first, and follow the stated application time. Use products designed for teeth and stop if pain or gum burning develops.
When should you seek dental care?
See a dentist before whitening if you have cavities, cracks, erosion, gum recession, visible restorations, or persistent sensitivity. Seek prompt care for severe pain or a chemical burn.
What should you ask the dentist?
Ask what causes the discoloration, whether enamel and dentin are intact, which gel concentration is appropriate, and whether fillings or crowns will change color.
