Problems solved by technology

[0005] However, the dental veneers currently on the market are made of hard materials such as polyethylene or polypropylene and have low tensile strength. When affixed to the teeth, it is easy to cause discomfort in the gums and insufficient fit with the teeth. In the case of uneven teeth or large gaps between the teeth That is, it cannot fit tightly, resulting in poor whitening effect
In addition, many products also have the problem of residual glue remaining on the teeth, resulting in drug residues and uncomfortable situations for users
Furthermore, the advantage of home whitening is that it is convenient and cheap, but the disadvantage is that it is difficult to control the dose. Once it is used too much, it will easily cause gum burns. Currently, the teeth whitening patches on the market have a small drug load and release quickly, which is likely to cause tooth sensitivity and irritation.
