10% carbamide H2O2: is used for at home in custom bleaching trays. If the custom tray that is placed in is not made properly, then it can irritate the gums, but this is generally a temporary.

Sometimes: The more powerful bleaching agents are best used with gum protection and in a professional setting. Less powerful chemicals are more forgiving and some are intended for home use. Carbamide peroxide is a common one and safe use varies based on the concentration.
