ABSTRACT:
An appliance for the application of a tooth whitening preparation comprises an applicator configured as a partial dentition arch. The applicator includes an outer casing panel, to which is adhered a formative inner liner having a relatively low softening temperature. The applicator is user fitted by immersion in hot water to soften the liner which is then impressed against buccal tooth surfaces. A tooth whitening preparation is deposited upon the buccal impressions formed in a fitted liner or is directly applied to buccal tooth surfaces. Thereafter, the appliance is worn for prescribed treatment duration, precluding dilution of the tooth whitening preparation as well as assuring against gingival contact with such preparation.
