Patent ID: 8747113

Claim:
A tooth whitening system, comprising: a) a generally flat moldable wax dental tray; b) the generally flat moldable wax dental tray being sufficiently moldable so that a user can form the moldable wax dental tray to generally match the configuration of the user's teeth, in use; c) the moldable wax dental tray including an upper gingival region and a lower incisal portion, the lower incisal portion being generally flat, and the upper gingival region being generally parallel to the lower incisal portion; and the dental tray including a left side and a right side, the left side being generally parallel to the right side; and the dental tray including a reduced portion provided generally centrally on the lower incisal portion; and the upper gingival region including a raised region and a valley, and configured so that, in use, the raised region and valley are adjacent to and free of contact with a corresponding raised region and valley of a user's tooth adjacent a user's gum line, respectively, and so that, in use, a gap is defined between the respective raised regions and valleys; d) the moldable wax dental tray including an absorbent layer provided on a region which faces a user's teeth; e) a tooth whitener provided on the absorbent layer of the moldable wax dental tray, the tooth whitener including: i) a carrier; ii) a whitening agent; and iii) an adhesive material, the adhesive material being sufficiently adhesive so that both the tooth whitener and the moldable wax dental tray formed to substantially match the configuration of the user's teeth, in use, are adhered to a user's tooth for a sufficiently long period of time to achieve a whitening of the user's tooth by the whitening agent; e) the tooth whitener includes, as a percent by weight: i) glycerin 10%-95%; ii) urea hydrogen peroxide .001-40%; iii) methyl hydrogenated rosinate .001-35.0%; iv) carbomer .001-10%; v) triethanolamine .001-5%; vi) spearmint oil 0.00-2%; and vii) sodium saccharin 0.00-2%; and g) the raised region and valley of the moldable wax dental tray, in use, with the tooth whitener on the moldable wax dental tray, causing the tooth whitener to be free of contact with the corresponding raised region and valley of the user's tooth and gum adjacent the gum line, so as to substantially prevent contact of the tooth whitener with the user's gum, in use.
