This product is not a denture or dental appliance. This item is only used to improve your appearance. Installation Instructions: Place the adhesive in a cup of hot (almost boiling) water for 1 minute. This will make them flexible and ready for customization. Use a mirror to firmly cover your teeth over your existing teeth. Press them firmly against your teeth and use your thumb to gently pat the impression material behind your real teeth. After 30 seconds, gently remove the teeth from your mouth and then place them in a glass of cold water to cool. The impression material will turn white when it hardens. Material: plastic packaging Includes: 1 set of tooth decals Note: Only by boiling water can the teeth become soft and adhere to the teeth.
