Is 44 carbamide peroxide safe

Carbamide peroxide breaks down into hydrogen peroxide and urea. Peroxide can move through enamel and dentine to oxidize some colour molecules, but it can also irritate exposed dentine and gum tissue.

A product’s label concentration alone does not predict the result. Cavities, cracks, gum recession, existing sensitivity, pregnancy, age, medicines, and restoration type can change the clinical decision.

Do not start a high-concentration product on your own. A dentist should inspect the teeth and gums, check for decay and cracks, confirm whether whitening can affect existing restorations, and provide a correctly fitting tray and schedule when appropriate.

Stop use and rinse if burning, ulceration, marked sensitivity, or gum whitening occurs. Do not place gel on the gums, swallow it, or extend the contact time.

Arrange an examination before use if you have pain, cavities, enamel wear, gum recession, untreated gum disease, or extensive crowns and fillings.

Seek dental advice for persistent sensitivity, a chemical burn, uneven colour, or symptoms after swallowing the product.

Is this concentration appropriate for my enamel, gums, age, and medical history?

How should the tray be fitted, how long should each application last, and what should I do if sensitivity occurs?
