2pcs Night Guard Gum Shield Mouth Trays For Bruxism Teeth Grinding No Delivery Type:Teeth Whitening Mouth Trays Quantity:2pcs  Weight: 2pcs: 13.6g Material: Soft Silicon Size: 6.5*6.2*1.3cm Color: Transparent Package includes:2pcs Teeth Covers Usage: 1. Practice wearing braces: put the braces on the upper gums and suck out the air between the braces and the gums, so that the braces can cover the surface of the whole row of teeth. Tips: practice twice, which is an important process of making dental braces. The lower dental braces are practiced in the same way. 2. Soften the denture base: pour the water at 80-90  into a flat-bottomed container with a depth of water that can immerse the denture base while the handle stays outside the surface of the water. Soak the denture base in water for 5-7 seconds and then take it out. Tips: the denture is very soft at the moment, so the immersion time should not be too long. When the denture is raised, it should be soft and elongated, and it is appropriate to begin to deform slightly. 3. Make dental braces: put the dental braces forward, wear them carefully and quickly on the gums, and continue to suck in step 1. The finger presses the joint of the denture and the tooth to make it thinner, while the tip of the tongue tightens the denture and the inside of the tooth. Tips: be quick. Be careful not to bite hard. The bracket is a little hot, but it won't cause any harm. 4. Trim the denture: after pressing the finger for 10-15 seconds, remove the denture and rinse it with water. Cut the excess material with scissors along the imprinted gingival line (the line between the teeth and the gums) on the denture base, and then cut off the handle. Tips: cut off the part above the gingival line so that the gel can only come into contact with the teeth and avoid irritating the gums. 5. Smear gel: apply the gel evenly on the outer tooth surface of the denture. the appropriate dosage of whitening gel is 0.5-1mm thickness. as long as the solid white gel is smeared all over the outer tooth surface. Tips: please dry the inside of the denture base with soft paper before applying gel, so that the coating can be evenly spread.
