How to Fit a Dental Guard / Grind Guard™:

     For best results we suggest you first test the molding process in your mouth and practice sucking the air, water and saliva out of the Guard before you start the heating process. Once you get the feel for what you will do when the guard is ready to mold, you can start the process of heating water. Bring about 4 inches of water to a boil and once the water is boiling, turn the heat source off, remove the water from the heat source and let it sit for a minute or two so it can cool slightly.

Securely hold 1 Guard by the triangular tab on the guard and gently place the guard in the water. While still holding on to the tab and keeping the tab above the water, wave the guard in the water for no longer than 10 seconds. You should see the guard start to appear more clear, soft, and droopy. Do not let go of the tab while dipping the guard in the warm water!

Once you have heated the guard and softened it, carefully put the guard in your mouth, fitting it to the top teeth. Gently press the guard to your teeth with your fingers and without biting down at all. Suck all of the air, saliva and water out of the guard and suction it to your teeth as tight as you can. Hold it on your teeth and press with your tongue and fingers as well to maintain a tight seal. Remove the guard from your mouth carefully after about 30 seconds to a minute and rinse under cold water. The guard should be formed tightly to your teeth and if you have a smaller mouth, then you can cut the guard with scissors to better fit your gingival margin. If the edges are rough, you can put the guard in warm water to smooth the edges.

If the guard does not fit to your satisfaction, you can repeat the steps again and try to make sure you get the best fit with the guard. Once you are satisfied with your fit, go ahead and cut the triangular tab with scissors to remove the tab. Again, if the edge is sharp from cutting it put some warm water on the edge or use a file and it will smooth out.

**Only wear one Guard at a time and clean with cool water with a cleaning substance of your choice.
