The basics Glam Metallic Deluxe Small Custom Fangs are designed for people with smaller teeth. They may fit either canines and/or incisors or bottom teeth. The benefits Fast, easy, comfortable, and totally realistic. Fang caps are shiny, rigid and beautifully contoured to look great in any mouth. The uses On-the-spot customizing is fast, easy, and only needs to be done once. Everything you need is included, no additional utensils and no boiling water necessary. The bottom line Once customized, fangs fit with a unique mold of your tooth inside that allows you to snap them on or off, quickly and easily (no thermoplastic partial plate around adjacent teeth).
