This mouth opener is helpful in such cases ☆ When performing the whitening procedure, there are key points that determine whether the finish will be beautiful or not. In the whitening steps, the surface of the teeth is wiped to remove moisture, but if moisture remains, the whitening gel will dilute and wash away. Therefore, it is necessary to wear a mouth opener and support it so that it does not directly touch the teeth. And then, apply the gel to the surface of the teeth. The whitening gel is applied evenly to each tooth so that it covers each one, but without wearing a mouth opener, saliva can dilute the whitening gel and reduce its effectiveness. ※ After application, when irradiating the teeth with an LED light (sold separately), you need to keep your mouth open, so it is much easier and you can whiten your teeth beautifully if you wear a mouth opener. By having a mouth opener, you can protect your teeth from saliva and fully demonstrate the whitening effect. If you want to get even brighter teeth than now! This product is recommended for those people!! ※ This product is sold as a mouth opener only. If you need a separate LED irradiation light or gel to whiten your teeth, please let us know in the comments. Please consider this opportunity.
