Our DIY dental gemstone kit contains UV glue. It can make you smile brightly, ensuring that the diamond attached to the tooth surface is not easy to fall off and has a certain level of safety. Its usage is very simple: first clean the teeth, then use a cotton swab to absorb the moisture on the surface of the teeth, brush the glue on the area where the diamond needs to be attached to the surface of the teeth, use a pen to attach the diamond protrusion surface, attach it to the surface of the teeth, and irradiate it with ultraviolet light for 60 seconds. Wait for it to dry. After use, the smile becomes more charming and radiant.
