Is whitening teeth with hydrogen peroxide safe
Hydrogen peroxide whitening can irritate gums and increase tooth sensitivity, and its risks depend on concentration, contact time, fit, and the condition.
The short answer
Hydrogen peroxide whitening can irritate gums and increase tooth sensitivity, and its risks depend on concentration, contact time, fit, and the condition of the teeth and gums.
What is the direct answer?
What does this question mean?
Risk rises when concentrated liquid contacts the gums, is swallowed, is used too often, or is applied to teeth with decay, cracks, exposed roots, or inflamed tissue.
What can you do next?
Do not use household peroxide or improvise a whitening mixture; have a dentist check the mouth and select a regulated product and tray that limit soft-tissue contact.
When should you seek dental care?
Seek care for chemical burns, persistent pain, marked sensitivity, swelling, or whitening used on a tooth with decay or a broken restoration.
What should you ask the dentist?
Ask what concentration and application time apply, whether cavities or gum disease need treatment first, and how non-bleaching options compare.
