Is it safe to use peroxide on your teeth

Using peroxide on teeth can irritate oral tissues, so the product, concentration, contact time, and swallowing risk must be assessed before use.

Use of a household or concentrated product is different from a dentist-supervised whitening product.

Do not use hair, cleaning, or industrial peroxide orally, and do not swallow any peroxide. For whitening, a dentist may examine enamel, fillings, gum health, and sensitivity before selecting a peroxide gel and tray.

Seek care for burning, white or peeling oral tissue, persistent pain, swelling, vomiting, or trouble breathing after exposure. Arrange a dental assessment if sensitivity continues or whitening is uneven, because the cause may be decay, erosion, or a restoration.

Ask which product and concentration are intended for oral use, how long it should contact the teeth, and what to do if it touches the gums. Ask whether existing fillings, crowns, exposed roots, gum disease, or sensitivity change the whitening plan.
