Hello.
We are Seoul Dia Dental Clinic in Magok, giving tired teeth a chance to rest.
The holidays have passed, and before we knew it, the season has entered the heart of autumn.
The morning air has become cool,
but what we hear at night is not only the sound of a refreshing breeze.
Sometimes, it may be the bruxism sound of “eeeeeek~ grrrr~”
heard quietly, yet intensely.
At times like this, nothing is more reliable than a bruxism device (night guard).
In the last post, in [3. Features by Type of Bruxism Device, Hard vs. Soft Comparison],
we looked at the characteristics and differences of each device together.
If you missed it, please take a look through the link below.^^
Today is the next story.
We will introduce how to maintain a bruxism device so you can use it for a long, long time.
Let’s take a look together with the mindset that “the more you use it every day, the more important daily care becomes!” ^^
How to Make a Bruxism Device Last a Long Time,
Consistent care determines its lifespan
- As soon as you wake up, clean it with lukewarm water

Magok Dental Clinic_ Cleaning the device
The device has worked hard all night, so be sure to wash it in the morning.
That’s because saliva, food debris, and bacteria may remain in the mouth.
Rinsing it with lukewarm water is best.
Avoid water that is too hot, as it can deform the device,
and instead of toothpaste, apply a small amount of neutral soap or a dedicated cleaning agent
and gently brush it with a soft toothbrush.
Also, because a bruxism device is made of plastic, it is vulnerable to heat.
If it comes into contact with hot water, its shape can easily warp.
Clean it in water that is moderately warm and comfortable to the touch.
- Two or three times a week, use a cleaning agent

Magok Dental Clinic_ Using a cleaning agent
Giving it a cleaning-agent bath about 2 to 3 times a week makes it even better.
On the market, there are denture cleansers and cleaning solutions specifically for night guards.
Fill a cup with water, add the cleaning agent,
soak it for about 15 to 20 minutes, then rinse it off—done!
You can manage odor, discoloration, and bacterial growth all at once.
However, leaving it in too long can weaken the material,
so keeping to the time limit is essential.
- Store it in a well-ventilated case

Magok Dental Clinic_ Using a dedicated storage case
After rinsing the device, the most important thing is where you store it.
The area above a humid bathroom sink is damp,
which makes it an ideal environment for bacteria to grow.
Therefore, place it in a dedicated case with good ventilation.
It is even better if you leave the lid half open instead of closing it.
When you take a break from using it for a while, wash it clean,
let it dry completely, and then store it in the case.
If you cover it while moisture remains, odors or mold can develop.
When using it again, rinse it with water once before wearing it!!
Following this one step makes it much more hygienic.
- If your tooth alignment or bite changes, get it checked

Magok Dental Clinic_ Checking the bite
A bruxism device is made to fit your teeth perfectly.
However, over time, tooth alignment or your bite may change.
In that case, do not just keep using it—have it checked again at the dental clinic.
Otherwise, if the device no longer fits properly, it may place strain on your jaw or teeth.
- If you drop it, do not just keep using it—have it checked

Magok Dental Clinic_ Checking the device
If you drop the device on the floor, it may look fine on the outside,
but there could be cracks or distortion inside.
If you wear it in that condition, your bite may become misaligned,
or your jaw may feel uncomfortable,
so if it falls, be sure to get it checked at the clinic.
Hard types usually can be used for more than 2 years, and soft types for about 1 year.
-
Clean it in the morning – gently rinse with lukewarm water
-
Cleaning-agent bath 2 to 3 times a week – address bacteria, odor, and discoloration all at once
-
Store it in a well-ventilated place – no bathroom!
-
Inspection is essential if it is dropped – internal damage is possible even if it looks fine
-
If tooth alignment changes, get re-examined – prevent bite imbalance
If you follow just these five points,
you can keep your bruxism device “like new for a long, long time.”
In the end, care habits determine the device’s lifespan.
Taking care of a bruxism device means
taking care of the lifespan of your teeth, the comfort of your jaw, and your quality sleep all at once.

At Seoul Dia Dental Clinic in Magok,
we carefully analyze each person’s bite condition, temporomandibular joint movement, and muscle tension
to make the most comfortable and accurate custom bruxism device.
One small habit can create a big change.
Tonight, before you fall asleep, just think of this one sentence:
“Today, I should let my teeth rest a little too.”
We will protect your good sleep and healthy smile
together with Seoul Dia Dental Clinic.
