Been much more stable over time and presents theadvantage of being successive annual reminders (afterwhitening booster).Chemical activation technique or photoactivatedtechnique, either with hydrogen peroxide or carbamidehigh concentration.After the patient already has braces and whitening gelneeds only to provide (individualized thermoplastic trays)and whitening agent: hydrogen peroxide and / orcarbamide.Three to four weeks or 3 to 7 days
