Hello.

Magaok Station Seoul Dia Dental Clinic is a place that never overlooks even the smallest changes inside the mouth.

The sealant series has now reached the final fourth part. Before getting into the main topic, let’s briefly review what a sealant is.

A sealant (pitting sealant) is a preventive treatment that lightly covers the deep grooves on the chewing surfaces of molars with a thin resin, helping block the spaces where cavity-causing bacteria can hide.

It does not require shaving down the tooth, and no anesthesia is needed. It is easiest to think of it as “closing the door in advance before a cavity develops.”

Now, the final part! Today’s question is:

“How can sealants be maintained for a long time?” This is the part many people are most curious about in practice.

Sealants are a simple preventive treatment, but they are not a coating that lasts semi-permanently without any care.

Because this treatment lightly covers the small grooves of the tooth, just knowing what to pay attention to in daily life can greatly extend its lifespan.

So from now on, Magaok Station Seoul Dia Dental Clinic will clearly explain the key care methods for keeping sealants in place for a long time!

Maintenance Guide for Pitting Sealants

  1. Be careful with very hard foods

Sealants are a thin resin material that covers the tooth, so when eating foods that require strong biting, such as walnuts, jerky with bones, taffy, or hard candy, they may come off due to impact.

“Hmm? It feels like something disappeared while chewing?” If you feel this way, be sure to get it checked.

  1. Check it together during regular checkups

Magaok Station Dental Clinic_Regular Checkup

It is difficult to check sealants on your own. Because the material is transparent or semi-transparent, it is hard to tell whether it has come off or cracked.

That is why it is safest to have it checked during regular scaling appointments as well.

For children in particular, a check-up every 6 months is essential.

  1. Brush carefully and thoroughly using the correct method

Magaok Station Dental Clinic_Brushing

Filling the grooves of the teeth does not completely block cavities.

It only blocks the grooves on the molars, so cavities can still develop on the sides of the teeth and between teeth.

Therefore, even after sealant treatment, floss is still essential, and brushing must be done carefully.

Pay special attention to the back and sides of the molars. If you follow just these three things, the cavity-prevention effect will improve significantly.

  1. If you feel discomfort in the sealant area, get it checked right away

When a sealant comes off, at first it may feel loose, and you may suddenly notice more food getting stuck there.

At times like this, there is no need to think, “Should I just wait a little?”

There is absolutely no need to. In fact, if it is left off for a long time, more force may be placed on that area while chewing, which can wear down the groove or cause a cavity. So getting it checked right away is the safest option.

  1. Keep in mind the insurance coverage period (2 years)

Magaok Station Dental Clinic_National Health Insurance

For children and teenagers (18 years old or younger), if a sealant falls off within 2 years, re-treatment is covered by insurance.

In other words, rather than worrying, “What if it comes off?” it is much easier to think, “If it comes off, I can get it done again!”

That said, if a cavity has already developed, insurance coverage does not apply, so it is smartest to get it checked right away if it comes off.
