Grillz glue (Fixodent) 10g is an adhesive that is specially developed to work with your mouth for a secure and comfortable hold. The natural moistures present in your mouth causes Fixodent's soft cream to change into an elastic-like membrane. This then grips your grillz tightly and securely whilst wearing them. A drop of fixodent inside the cap before placing it over the tooth might be needed to make them stay on.
