How long does the in-office teeth whitening procedure take?
办公室牙齿美白程序需要多长时间？
For in-office laser teeth whitening, a good two hours is needed to complete the procedure. Your hygienist will begin by making a record of your current teeth shade and taking impressions of your teeth to create custom-fitted trays. This will be followed by a gum protection procedure and the application of the whitening gel. Curing light or laser will be used to activate the bleaching agent. The teeth will rest with the solution for about an hour and can be reapplied occasionally until desired results are achieved. Once the best shade is reached, fluoride will be applied to ease any tooth sensitivity.
对于办公室内的激光牙齿美白，需要两个小时才能完成该程序。 您的卫生员将首先记录您当前的牙齿颜色并获取您的牙齿印模以创建定制的牙托。
接下来是牙龈保护程序和美白凝胶的应用。 将使用固化光或激光来激活漂白剂。 牙齿将在溶液中停留大约一个小时，并且可以偶尔重新涂抹，直到达到预期的效果。 一旦达到最佳色调，将使用氟化物来缓解任何牙齿敏感。
