Literally the simplest thing to use! I boiled water in my teakettle until it was almost to a boil and pour water into a thermos. Put around 10 beads of the adhesive and use a spoon to get them once they’re transparent. Put on your desired tooth and just use your finger of toothpick/floss stick to help it so its not too showy when u smile. If it doesn’t work well just throw your tooth with the adhesive back in the hot water and push the adhesive around in the tooth to pack it back in.
