Is hydrogen peroxide bleach safe for teeth
Hydrogen peroxide can irritate gums and tooth surfaces when used incorrectly, so whitening needs professional guidance.
The short answer
Hydrogen peroxide can irritate gums and weaken tooth surfaces when used in the wrong concentration or for too long, so whitening needs professional guidance.
What is the direct answer?
What does this question mean?
Peroxide whitening works by oxidizing colored molecules within enamel and dentin. The risk of sensitivity or soft-tissue irritation depends on concentration, contact time, barriers, existing decay, exposed roots, and how the product is used.
What can you do next?
Do not swallow household bleach or apply concentrated peroxide to teeth or gums. Have decay, leaking fillings, gum recession, and enamel defects checked before choosing a whitening method; use only a product and instructions supplied for oral use.
When should you seek dental care?
Seek dental advice before whitening if you have pain, cavities, gum disease, ulcers, or exposed roots. Stop use and obtain care for a chemical burn, severe sensitivity, swelling, vomiting, or trouble breathing.
What should you ask the dentist?
No household product should be substituted for an oral whitening system; ask a dentist which peroxide concentration and delivery method fit your mouth.
