Disposable dental mouthpiece-strip which has been pre-impregnated with dental substance which can either be placed in the mouth by the user or inserted in the mouth by a dentist for oral treatments, such as teeth whitening treatments, fluoride treatments, or medical treatments, such as the application of anasthetic or antimicrobal / antiseptic treatments. The mouthpiece-strip is made with a foldable structure such as a thin strip of wax with a section of porous material (sponge) that holds the treatment dental product (liquid or gel). The mouthpiece-strip is disposable; the amount of time it is worn is determined by the type of dental treatment. The mouthpiece-strip may be adjusted in size by cutting it with scissors. The wax used for the mouthpiece is non-toxic and allows for a perfect adjustment in the mouth by contouring to the teeth during adjustment by the user. To enhance the fit in the mouth, the inner surface of the mouthpiece-strip may contain a thin layer of non-toxic sticky adhesive. The porous (sponge) strip attached to the wax strip is an inert, nontoxic material which is easy to process and inexpensive. It is attached to the wax strip with a non-toxic adhesive.

The present invention relates to compact tooth whitening devices. The compact tooth whitening device includes an electromagnetic radiation source and an applicator that is removably attached.

The method of the present invention is directed to the storage and dispensing of a peroxide containing tooth whitening composition. During storage and subsequent use the composition in the storage chamber must be maintained segregated from the applicator surface. This is accomplished by delivering the peroxide containing tooth whitening composition from the storage chamber through a delivery channel having a length and a cross-sectional diameter sufficient to preclude the migration of moisture and the enzyme catalase from the application surface to the storage chamber. The composition is applied to teeth by means of bristles, a sponge surface or fibrillated surface. This applicator can be used with both aqueous and non-aqueous peroxide containing tooth whitening compositions.

A nonaqueous gel composition for tooth whitening, comprising: (A) tooth whitening ingredient having a relative permittivity of 17.0 to 43.0 (at 25° C.) and a vapor pressure of 0 to 7000 kPa (at 25° C.), (B) substance that is soluble in the tooth whitening ingredient and is precipitated by an aqueous solution of calcium chloride, and (C) gelling agent, which nonaqueous gel composition contains substantially none of water and peroxide. This tooth whitening component can penetrate into the enamel surface layer of teeth to thereby alter the optical properties, such as refractive index and reflectance, of the enamel so that the enamel is apparently whitened. The whitened teeth can be restored to the original tooth color in a reversible manner in the presence of water. Further the persistence of reversible whitening effect can be strikingly enhanced by the nonaqueous gel composition.
