Our dental gem kit includes UV glue. Its usage is straightforward: apply the resin to the area of the tooth where the gem is to be affixed, use a pen to adhere the raised surface of the gem to the tooth surface, and then expose it to ultraviolet light for 60 seconds until it dries and sets. That's it! This product comes in two different types of diamonds: one is a colored diamond, which resembles a rainbow in color and reflects different hues at various angles and under different lighting conditions; the other is a white diamond, which is also transparent but more translucent than the colored diamond. It's easy to remove and install, secure, and resistant to breakage or wear. You can still brush your teeth and eat without any hassle; they can serve for a long time, maintaining your charm.
