摘要:
Disclosed herein is a pair of dry type patches for teeth whitening, having a patch for upper teeth and a patch for lower teeth, in which the patch for upper teeth has a shape different from the patch for lower teeth, and each patch has a controlled width and shape such that the contact area of each patch with gums is minimized. In the patch for upper teeth, a central portion covering right and left upper central incisors is widest. In the patch for lower teeth, either portion covering right and left lower canine teeth is widest. Since the dry type patches covers all the portions of the teeth while minimizing the contact area with gums, no or little irritation is caused and wearability is excellent.
