Description

Teeth bleaching patch with discolor layer with stable discoloration layer

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tooth whitening patch having a stable discoloration layer, and more particularly, to a tooth whitening patch which is provided with nutrition for a tooth and attaches a tooth whitening patch to a tooth, The present invention relates to a tooth whitening patch having a discoloration layer with stability that enables a user to easily determine a time point at which a tooth whitening patch can be detached from a tooth by changing a color of a color fading layer that is guaranteed.

The causes of tooth discoloration are endogenous factors and exogenous factors. Tooth discoloration due to endogenous factors may be caused by deposits of food waste, coffee, tea, etc. in the dentin of the teeth, pigmentation of the dental plaque or soft deposits by the coloring matter, or bleeding of other colored bacteria or gingiva and excess of fluorine Ingestion, mineral dirt of the factory, and chemicals.

In addition, tooth discoloration due to extrinsic factors is caused by overdosing of tetracycline antibiotics in the case of dental neuropathy, silver amalgam as a prosthetic supplement, and so on.

In recent years, as interest in cosmetics has increased, interest in tooth whitening has increased. Various methods for treating tooth discoloration have been developed in response to this. Among them, typical methods of treating tooth discoloration include a transient method of covering a discolored tooth with a jacket crown and a surgical method such as scaling, which are troublesome and expensive.

Another method is brushing toothpaste using a bristle toothbrush or a toothbrush with a simple addition of an abrasive agent. This is not only unsatisfactory for the whitening effect, but also physically abrades the enamel surface and the cervical portion of the tooth surface, There was a problem of making sensitive teeth.

Thus, various types of whitening patches that directly contact the teeth to increase the whitening effect have been studied. U.S. Patent No. 5,326,685 discloses that a gel-type tooth whitening agent is put between a porous material such as a sponge and a water- And attaching it directly to the posterior teeth. In this case, while the tooth is in contact with the teeth, the teeth whitening agent gradually acts on the teeth through the porous material, thereby exhibiting the whitening effect.

Korean Patent Laid-Open No. 10-2001-0013448 discloses a tooth whitening patch which covers a tooth enamel-attached layer containing a tooth whitening agent on a thin and flexible strip and provides adhesion between the tooth surface and the strip .

However, although the demand for the tooth whitening patch products is increasing due to the ease of use and excellence of the effect, it is difficult to determine how much time is required to attach and detach the patch after it is attached to the tooth. There was an inconvenience to doing.

Of course, although effective guidance on the attachment time is provided on the instruction manual, there is still inconvenience in this case in that the user must perform the time measurement directly.

In order to solve these problems, Applicant has disclosed a patch for tooth whitening laminated in the order of adhesive layer, drug layer, discoloration layer and coating layer in Registration Utility Model No. 20-0471737.
