Fake fangs are often supplied with their own adhesive, but if you want to use them more than once, you may need own supply. While denture fixative may seem an obvious solution, this is designed to stick things to gums, not teeth, and therefore is not always effective. With a few readily available household ingredients, you can make a glue that is safe, nontoxic and sticky enough to get the job done.
Pour half the water, the corn syrup and the vinegar into a saucepan. Turn on the heat and bring the mixture to the boil, stirring continuously. Remove it from the heat.
Mix the remaining water with the cornflour in a separate bowl until it has a smooth consistency. Slowly pour the contents of the bowl into the saucepan while the mixture is still cooling down. Stir thoroughly.
Pour the glue into an airtight container and allow it to cool to room temperature. Although it can be used right away, it will have greater adhesive power if it is left to cure for a day or two.
Make sure you teeth are clean and as dry as possible before gluing on the fangs. This will help them stick better. A few small dabs of the glue evenly spaced out of the fangs will be more effective than using a larger quantity. It will also make the fangs less messy to remove. Avoid eating or drinking anything while the fangs are glued into your mouth because it may dislodge the fangs.
Although this glue is safe and edible, it should not be consumed to excess.
