Is it ok to brush teeth with hydrogen peroxide
Brushing with household hydrogen peroxide does not replace fluoride toothpaste and may irritate oral tissues.
The short answer
Brushing with household hydrogen peroxide is not a substitute for fluoride toothpaste, and the risks depend on the product concentration, exposure, swallowing, and contact with oral tissues.
Why is toothpaste different from hydrogen peroxide?
Toothpaste combines controlled abrasives, fluoride, detergents, and other ingredients designed for brushing. Hydrogen peroxide is an oxidising agent, so direct or repeated contact can irritate the gingiva and oral lining and may increase sensitivity.
How can you brush and clean between teeth safely?
Brush with a soft toothbrush and fluoride toothpaste, spit without swallowing, and clean between teeth. If you want whitening, have the cause of discolouration and the condition of your enamel and gums assessed before using a peroxide-containing product made for oral use.
When should peroxide exposure be assessed by a dentist?
Stop the practice and seek advice if burning, peeling, ulcers, swelling, or ongoing sensitivity occurs. Prompt assessment is appropriate after swallowing a significant amount or after contact with the eyes or skin.
What should you ask about oral peroxide products?
Ask whether a specific peroxide product is intended for oral use and how it should be applied. Ask about fluoride protection, existing restorations, gum recession, sensitivity, and a suitable whitening alternative.
Frequently asked questions
Can hydrogen peroxide replace toothpaste?
No. It does not provide the complete formulation and fluoride function of toothpaste.
What if I accidentally swallow a small amount?
Do not repeat the exposure; rinse your mouth and contact a poison service or clinician for product-specific guidance if symptoms occur.
