NOTE: Night Guards (for teeth grinding) do not require a final fitting. If you purchased a Night Guard, skip this step.
Before using your sports mouthguard, you must mold the bite marks of your lower teeth into the bottom of the mouthguard. This will give you a more comfortable, secure bite and will allow your lower jaw to lock into the mouthguard!
This instructional page and the How-To video below are meant to be used together, so review both before beginning the Final Fitting process. You must follow each step precisely!
You will need 1 pot of boiling water, 1 bowl of room temperature water, and a timer. See photo below for Final Fitting sample.
WARNING: If you do not follow these instructions correctly and ruin the fit of the mouthguard, we are not responsible.
Try the mouthguard in so you can see exactly how it feels to have it fully snapped in place. When you mold the bottom bite marks into it, you need to know that the mouthpiece is properly snapped into place before biting into it. After it's fully snapped in place, practice biting into it to find your natural, correct biting position.
After bringing pot of water to a full boil, turn off the flame and wait 15-30 seconds for the water to calm down. You don't want the pot of water at a rolling boil when you're holding the mouthpiece in it because some water may splash up and burn your hand.
Set your timer for 60 seconds. Hold the top/front part of the mouthpiece (by the little notch in the front/center) with your fingertips. Do not use tongs or any other tools. Start your timer and dip only the bottom part of the mouthpiece in the water. You only want to heat up the area that your bottom teeth are going to bite into.
Keep the bottom of the mouthpiece in the hot water for 60 seconds. If the heat from the steam coming off the water gets too hot for your hand, just switch hands. You might have to switch hands back and forth a few times during this process. Just make sure to keep the bottom of the mouthpiece in the water for the entire 60 seconds.
Once 60 seconds is up, give the mouthpiece a quick dunk in and out of the bowl of room temperature water. The mouthpiece may feel a little soft, so be sure to handle it very gently. You don't want to distort the overall shape. Get the mouthpiece snapped in place, then slowly but steadily bite into it. Make sure you bite in your natural, correct biting position.If you bite incorrectly into the mouthpiece, it will not feel right when you use it, and you will need to remold it. Do not bite all the way through the mouthguard. You want deep, visible bite marks in the bottom of the mouthpiece, but you do not want to bite completely through it.
Stay biting for 15 seconds, then remove the mouthpiece from your mouth and rinse under cold water for 15 seconds. Your mouthguard should now have deep, visible bite marks, as shown in the sample photo below. If the bite marks on your mouthguard look good, and the bite itself feels good, you're done! If the bite doesn't feel deep enough, or if the bite position is off, just repeat this process and correct whatever mistakes you might have made the first time. Keep in mind that our thicker mouthguards do require a deeper bite than our thinner mouthguards, so you may need to bite down a little harder to achieve deeper bite marks.
