Hello.

This is Magok Station Seoul Dia Dental Clinic, which reduces the burden on patients and improves dental health.

These days, so many people are looking for dental clinics on weekends, right?

In particular, Saturday is a day when people can take a short break from their daily routine,

so there has been a noticeable increase in the number of people coming in for checkups and treatments they had been putting off.

After busy weekdays,

for those who think, “I really need to go to the dentist this weekend,”

I believe this article will be exactly what you need!

Let me share a dental story from Seoul Dia Dental Clinic at Magok Station.

In the last post, in [Part 4: Glass Ionomer (GI) Cavity Treatment Process],

we went through step by step how cavities are filled.

If you missed it, checking the link below first will make it much easier to understand.

Now, the treatment is finished.

Many people ask, “So it’s all done now, right?”

But... this is where the real start begins.

That’s because post-treatment care is what completes the treatment.

No matter how well it is filled with good materials,

cavities can return if your daily habits are not good.

So today, I’ll neatly and simply organize the precautions you should definitely know after treatment.

Precautions After Glass Ionomer (GI) Treatment

  1. Right after treatment, please wait a little before eating

Glass ionomer (GI) needs a little time right after treatment

to become fully hard.

In particular, with self-cured GI (the type that hardens on its own),

it is vulnerable to impact before it is fully set.

Therefore, it is best to avoid eating for about 30 minutes to 1 hour after treatment,

and avoid hot or hard foods for the time being.

Start with soft drinks like water.

If you have a habit of chewing on only one side,

chewing on the opposite side of the treatment area is also a good idea.

  1. Do not brush too hard for a day or two

The treated area is still sensitive.

If you brush too hard, the border between the material and the tooth can be damaged.

Therefore, use a toothbrush with soft bristles,

and choose a mild toothpaste that does not irritate the mouth.

When brushing, think of gently rubbing along the boundary between the tooth and gum

at a 45-degree angle!

Remember it as “massage gently rather than scrubbing hard.”

  1. Take a break from sticky or sugary foods for a while

Sticky foods such as chocolate, jelly, and caramel

can stick to the treated area and come off.

Especially in the early stage after treatment,

GI is not yet fully hardened,

so it is better to avoid these foods for a while.

If you manage with the thought of “let’s just hold off for a few days,”

the results will last much longer.

  1. Regular checkups are essential

Many people say, “Why do I need to go to the dentist again after treatment?”

but in fact, regular checkups are the best way to prevent recurrent cavities (secondary cavities).

If food gets caught around the treated area

or a small gap forms, bacteria can multiply again.

Therefore, it is generally good to have regular checkups once every 6 months to 1 year

to check the condition of the material.

  1. Do not assume that “once treated means it’s fine forever”

GI is an economical material covered by insurance,

but its durability is lower than metal (amalgam) or resin.

Therefore, over time it may wear down or the edges may chip slightly.

If you think, “Something feels a little off,” or “Something feels caught when I chew,”

don’t just brush it off and get it checked right away.

If caught when it is still a small issue, it can be treated simply again.

To summarize after Glass Ionomer treatment!

  1. No eating for 1 hour after treatment

  2. Avoid hard and sticky foods for a few days

  3. Brush gently

  4. Have regular checkups every 6 months to 1 year

  5. Visit the dentist immediately if you notice anything unusual

Glass ionomer (GI) is

a representative material for which “treatment is quick, and care is important.”

In other words, your post-treatment care habits determine the lifespan of the treatment.
