Magaok Station Dental Clinic_5. Why Inlay Restorations Fall Out [Causes of Detachment and When Rebonding Is Possible?]

Hello!

Near Exit 3 of Magaok Station,

This is Seoul Dia Dental Clinic, working hard even on weekends.

On this golden weekend, we’re back with the 5th installment of our inlay series for your dental health. Yesterday, we talked about “pain after inlay treatment.” If you missed it, you can lightly review it through the link below and the flow will connect nicely! And today, I’d like to talk about something truly real-life.

“Why does the inlay keep coming off after it’s bonded?” “It fell out while I was chewing… can it just be reattached?” “It’s moving even when I’m not doing anything…”

This inlay restoration detachment issue is something many people experience more often than expected! From the causes to how to deal with it, Seoul Dia Dental Clinic will break it down clearly for you today.

A 3-minute weekend read—don’t miss it!

"Why did it come off?"

Two major causes of inlay detachment

1. Problem with the restoration itself

First, let’s look at treatment-related factors. During the process of making and bonding an inlay at the dental clinic, Detachment can occur for the following technical reasons.

• Insufficient bonding strength

If the adhesive was not applied evenly to the tooth surface, or if the dryness level was not appropriate, the bonding may not be completed properly.

In particular, if the cavity area was wide and the walls were thin, there is a higher chance that the retention of the bond will be reduced.

• Inadequate adjustment of the bite (occlusion)

If the restoration is bonded too high and force is concentrated too much on one side, the chance of detachment increases over time.

This is the case when it suddenly goes “pop” and falls out while chewing hard food.

• Improper tooth shaping

If the shape after tooth reduction is inaccurate, the surface area for the inlay to seat properly decreases, and retention can weaken accordingly.

It’s a bit like how vinyl gloves don’t cling well when they’re too wet.

2. Patient habits

The second cause comes from everyday habits that are easy to overlook.

• Bruxism, clenching the teeth

Repeated pressure during sleep, without you realizing it, puts stress on the restoration beyond the bond itself.

Especially if you tend to chew only on one side, the likelihood of detachment rises a lot.

• Habit of eating hard foods

Dried squid, peanuts, scorched rice, biting ice... Our teeth are put through a lot with various foods more than we think.

Although an inlay is durable, it can still be vulnerable to forces that act like a lever.

• Habit of touching it with your hand

If you force floss in roughly or keep touching the restoration with your tongue tip or fingernail, small gaps can open and weaken the bond.

An inlay restoration that has detached, can it just be bonded again?

There’s no need to panic just because the inlay came off. If the restoration itself is intact, the inside of the tooth is fine, and you come to the dental clinic right after it falls out? In most cases, rebonding is enough to solve the problem.

But here’s the thing... If you delay it for several days thinking, “Ah, I’ll go later,” food debris, saliva, and bacteria can get in during that time. Then simple rebonding becomes difficult, and a new restoration may be needed.

Also, if it falls out once, you might think, “Well, that could happen once in a while.” But if it keeps coming off two or three times? That can be a sign that it’s not just a bonding issue, but that there may be a problem with the tooth root or the gums themselves.

In that case, crown treatment, gum treatment, and in severe cases, even root canal treatment may be necessary.

That’s why Seoul Dia Dental Clinic emphasizes this! Be careful with hard foods, don’t chew only on one side, check your bite regularly, and visit the clinic quickly if anything seems off!

If you follow just these four things well, you can use your inlay restoration much longer and more reliably. Don’t forget that maintenance is an extension of treatment.

So, here’s today’s one-line summary.

“Don’t panic if your inlay falls out—come to the dental clinic first!”

There’s always a reason an inlay comes off. There may have been a small mistake in the bonding process at the dental clinic, or you may have been chewing too much, grinding too much, or touching it too much(!) in daily life.

But the important thing is! The key is not simply that it came off, but why it came off. If the cause is properly identified, it can be decided clearly whether to rebond it, remake it, or consider a different treatment.

And yes, the first detachment may be a mistake, but if it happens two or three times, it’s a signal. There may be another underlying issue hidden in the tooth root or the gums.

In that case, instead of thinking, “It should be fine, right?", the smartest response is to have it checked quickly.

An inlay is a small restoration, but if it’s managed well, it can last with you for 10 or even 15 years. So don’t just treat today’s information as simple trivia—take a moment to check your daily habits too!

Tomorrow, in the final 6th part, we’ll share useful tips for using your inlay well for a long time, so for those thinking, “I had it bonded to last long, so let’s use it well for a long time!” we’ll see you on Seoul Dia Dental Clinic’s blog tomorrow as well!
