Is it safe to whiten teeth with hydrogen peroxide
Hydrogen peroxide whitening depends on concentration, contact time, formulation, and the condition of your teeth and gums, so household use needs.
The short answer
Hydrogen peroxide whitening depends on concentration, contact time, formulation, and the condition of your teeth and gums, so household use needs professional guidance.
How can hydrogen peroxide affect your mouth?
Hydrogen peroxide is an oxidizing ingredient in whitening products. Direct contact with oral tissues can irritate them, and swallowing an unsuitable product adds exposure.
What should you do before using peroxide to whiten teeth?
Do not improvise a peroxide rinse or use concentrated solution; a dentist can examine the mouth and select a controlled product or procedure.
When does peroxide whitening need urgent dental advice?
Get advice before use with cavities, cracks, ulcers, recession, or enamel wear, and stop for burning, swelling, severe sensitivity, or ingestion.
Which peroxide concentration is suitable for your teeth?
Ask which concentration and delivery system are appropriate and how the gums will be protected.
Frequently asked questions
Can another condition cause similar symptoms?

What should I bring to the visit?
Bring your medication list and describe when the problem began, what triggers it, and what has changed.
