Nightguard vital bleaching, or NGVB, which involves the use of a 10 percent carbamide peroxide in a custom-fitted mouthguard, has been used with much success since its introduction in 1989. Normal bleaching treatment time is one to two weeks, although times may be extended to months for difficult stains. When used in a professionally supervised manner, nightguard vital bleaching is as safe as any other routinely used dental treatment.
夜间护齿美白（Nightguard vital bleaching，简称NGVB），是指在定制的口腔护具中使用10%的过氧化脲，自1989年推出以来已取得了很大成功。正常的美白治疗时间为一至两周，不过对于顽固污渍，治疗时间可能会延长至数月。在专业监督下使用时，夜间护齿美白与其他常规牙科治疗一样安全。
