Is rinsing with hydrogen peroxide safe for your mouth?

Hydrogen peroxide rinses can irritate oral tissues, and the risks depend on product strength, dilution, contact time and the reason for use.

How can concentrated peroxide harm the mouth lining?

Hydrogen peroxide is an oxidising chemical that can inflame or damage mouth lining when too concentrated or held too long. It does not replace brushing, interdental cleaning or treatment.

What should you avoid when using peroxide as a rinse?

Do not use household peroxide or improvise a mixture. If an oral product is recommended, follow its label, spit it out, avoid swallowing and stop if tissues sting or whiten.

When do peroxide rinse symptoms need urgent care?

Seek urgent help after significant swallowing or breathing trouble; arrange dental care for ulcers, bleeding, bad taste or swollen gums.

What should you ask before using a peroxide rinse?

Ask why it is being considered, which formulation applies, how long to use it and what treats the underlying problem.

Frequently asked questions

Can peroxide cure gum disease?
