Boiled Water
What you need: pot, bowl of cold tap water, slotted spoon or fork, heater/gas or electric* stove, a mirror.

Do not rush through steps 1-4

1.Fill a 4-6” pot with approximately 3” of water. Let the water come to a rolling boil. If using a gas stove, simply turn the heat off, if using an electric stove, turn the heat off and remove the pot from the heat source*. Have a bowl of cold tap water nearby.

2.Place the CustMbite MVP face down in the boiled water for 20 seconds.

3.Remove the mouthguard from water with a slotted spoon or fork and dip into the cold water for 3 seconds.

4.Carefully place the mouthguard in the mouth, lining up the mouthguard with the center of the teeth. Do not bite the mouthguard into place, but lightly close your mouth so that your teeth come in contact with the mouthguard.

5.Close your mouth and gently suck on the mouthguard until it has molded into the shape of your upper teeth. In 45 seconds to 1 minute, you should be able to open your mouth and the mouthguard should remain securely in place. Leave in your mouth for 2 additional minutes. You may then continue to leave the mouthguard in your mouth or remove it and leave in the cold water. In 5 minutes you will have a final snug fit comparable to a dentist-office custom made mouthguard.
If fitting over orthodontic braces, do not suck on the mouthguard during forming.

Microwave (Microwave needs to be 1100 watts or more to be effective)

What you need: Microwave on the highest setting, bowl of cold tap water, large paper towel, slotted spoon or fork, a mirror.

Do not rush through steps 1-5

1.Wrap the CustMbite MVP mouthguard in a wet paper towel. Have a bowl of cold tap water nearby.

2.Place the wrapped mouthguard in a microwave on high setting for 1 minute – be careful because the paper towel will get hot. Do not remove the mouthguard with your hands.

3.Remove the CustMbite MVP with a slotted spoon and cool it – still wrapped in the paper towel – in the cold water for 3 seconds.

4.Unwrap the MVP from the paper towel.

5.Carefully place the mouthguard in the mouth, lining up the mouthguard with the center of your teeth. Do not bite the mouthguard into place, but lightly close your mouth so that your teeth come in contact with the mouthguard.

6.Close your mouth and gently suck on the mouthguard until it has molded to the shape of your upper teeth. In 45 seconds to 1 minute, you should be able to open your mouth and the mouthguard should remain securely in place. Leave in your mouth for 2 additional minutes. You may then continue to leave the mouthguard in your mouth or remove it and leave in the cold water. In 5 minutes you will have a final snug fit comparable to a dentist-office custom made mouthguard.
If fitting over orthodontic braces, do not suck on the mouthguard during forming.

Note: The CustMbite MVP mouthguard can be reformed at any time if the fit needs to be refined. If the mouthguard is too long you may shorten it by trimming before fitting. If the mouthguard is too short you may stretch it after heating it.

The National Federation of State High Schools’ mandate for wrestlers with braces will require both upper and lower mouthguards.
