Material: Copper 14K gold, white gold inlaid with 5A zircon Each set of braces comes with edible grade fixed wax and medical tweezers as gifts usage method: 1. Place the white silicone into the groove of the gold tooth. 2. Soak the gold teeth (silver teeth) together with silicone in hot water at around 70-80 degrees Celsius for about 15-30 seconds to soften the silicone. (Note that do not use boiling water or hot water, otherwise the silicone will be soaked and unusable) 3. Put the golden teeth (silver teeth) into your mouth and gently bite them with your upper and lower teeth. The soft silicone is pressed by the teeth to adjust its shape in the user's mouth, matching with the tooth shape, and playing the role of fixing and shaping. 4. If the shaping effect is not good, it can be repeated until satisfactory. 5. After each use of braces, rinse with clean water and dry in the sun. Store well. Usage suggestion: 1. Wear braces at once. If you have multiple things in your mouth, you won't adapt well to changing anything. Just stick to wearing braces two or three times to adapt. Please remove braces when eating. Maintain oral hygiene.
