Why Heat Can Damage Your Night Guard
There are several reasons a night guard can lose its original shape, and one of them is environmental exposure. Heat can play an important role in the durability of dental products. According to the Cleveland Clinic, exposure of the night guard to the sun or cleaning it with hot water may damage it.
Very high temperatures tend to weaken some materials used in dentistry, which makes them more susceptible to distortion under pressure or weight.
Even the kind of material used in your night guard may affect its response to heat. Most night guards use EVA , acrylic, or even silicone substances. While these materials are very tough, they can soften when they come into contact with high temperatures.
How to Protect Your Night Guard During Summer Travel
There are several strategies you could do to protect your dental guard from warping under the heat such as:
Avoid leaving it in direct sunlight
Sun exposure can raise the temperature inside the case quickly, especially in outdoor or window areas, which may soften the material over time.
Keep it out of hot cars or enclosed spaces
Parked cars can get extremely hot in minutes. Even if the night guard is in a bag or case, trapped heat can still affect its shape.
Don't rinse it with hot water
Use cool or lukewarm water when cleaning your night guard. Very hot water can soften thermoplastic materials and affect the fit of the device.
Pack it in your carry-on luggage
This makes sure that it is not subjected to extreme temperatures in the cargo compartment of the plane.
Let it cool naturally if it feels warm
If your night guard gets exposed to heat, allow it to return to room temperature before using or storing it again. Avoid trying to fix it with heat or reshaping methods.
What to Do If Your Night Guard Is Damaged by Heat
Wearing a night guard that has been damaged by heat is not recommended. Warping in the edges, alteration in texture, looseness, or even irritation in your gums and teeth are some signs that can tell you that the bite guard might not be ideal for use anymore.
If you continue using a dental guard that is worn out, it will be painful and not serve its intended purpose of dealing with bruxism.
The best thing to do in this situation is to avoid trying to fix the dental guard yourself, as this may cause further damage. Instead, replacement is often the safest option, along with better storage and care moving forward.
