ABSTRACT:
There is disclosed a novel process and a [material] composition for brightening teeth, together with a novel use of old compositions for brightening teeth. The novel process and use each comprises [comprises] the [construction] placing of a splint around the tooth or teeth to be brightened, [followed by the insertion within the splint of] with a brightening agent [selected from one of many peroxide groups] comprising a composition capable of sustained nascent oxygen release. The splint is constructed so that the splint is relatively liquid tight [to the gingiva]. Preferably, the brightening agent is periodically renewed during the day and can be mixed with various other agents to increase the nascent oxygen release [aerating factors]. In one embodiment, the [perioxide] peroxide that is used is a 10% solution of carbamide peroxide mixed with a water free gel.
