Molar cavity treatment cost,

The 2 real reasons it differs from hospital to hospital

Cavity treatment cost

Hello.

I am Oh Tae-hoon, chief director of D-Day Dental Clinic.

When a post like this is uploaded to an online community, comments start pouring in.

"Isn't that overtreatment?"

"Could that clinic be on a blacklist?"

"If it were me, I’d ask for a refund."

But is that really the case?

For the same two cavities, why is it 400,000 won at one place and 700,000 won at another?

It is not simply because of overtreatment.

Today, I will honestly explain the real reasons why cavity treatment costs differ from clinic to clinic, which many people are curious about.

If you read this to the end, you will be able to make a smart choice without unnecessary suspicion.

​​1. Why cavity diagnosis standards differ by doctor​​2. Why treatment methods and materials differ​​
  1. Cavity diagnosis standards,

Why doctors differ

Many people say, "Clinic A says I have 2 cavities, but Clinic B says I have 5."

Who is really overtreating?

In fact, this often comes not from overtreatment, but from differences in the 기준 used to examine cavities.

Cavities do not start out black from the beginning.

In the early stage, the tooth surface often becomes slightly white from demineralization,

or appears as brown spots.

If those brown spots progress further, they turn black. So the issue is this.

It is about how early cavity conditions are judged.

In adults, early cavities often stop progressing or become inactive.

I also usually tell adult patients to observe early cavities over time.

However, regular checkups are essential in order to continuously monitor the progress of cavities.

If you do not receive regular checkups, early cavities can progress into moderate cavities,

and moderate cavities can progress into deep cavities that require root canal treatment.

This is where the number of diagnoses differs by dental clinic.

Some count even early cavities, while others only count moderate or more advanced cavities that need immediate treatment.

Another important point is the difference in diagnostic equipment.

  1. Clinics that only examine visually

  2. Clinics that take only standard X-rays

  3. And clinics that also perform detailed imaging

The diagnostic accuracy of these approaches is clearly different.

Especially interproximal caries, which occur between teeth, are often completely invisible from the outside.

When viewed on an X-ray, they may appear dark or show cavity progression in a triangular shape,

while looking fine to the naked eye.

Whether or not these hidden cavities are detected will inevitably affect the diagnosis count.

  1. Treatment methods and materials,

Why they differ

Even for the same cavity, the cost can vary greatly depending on how it is treated.

For example, let’s say we are treating a cavity that formed between the teeth.

There is a method where only the affected area is minimally removed and filled with composite resin,

and another method where a slightly larger area is removed and restored with an inlay.

And if the cavity is deep and requires root canal treatment, a crown must also be placed.

Of course, the cost rises in the order of resin < inlay < crown.

But what matters here is not simply recommending a more expensive treatment,

but choosing the appropriate treatment that matches the patient’s tooth condition.

If the cavity is small and someone says to put on a crown, that would be overtreatment.

On the other hand, if the cavity is deep and resin is not sufficient,

forcing a resin filling will cause problems again later.

The cost also varies depending on the type of material used.

Even for the same inlay,

  1. Gold inlay
  2. Ceramic inlay
  3. Zirconia inlay

have different prices.

I always tell patients this.

This tooth is in this condition right now, and this is the most appropriate way to treat it. However, if you have budget concerns or other considerations, we can also think about other options together.

When establishing a treatment plan, it is most important that the patient fully understands and agrees.

It is not something the doctor decides unilaterally; rather, the doctor explains the patient’s condition and the reason for treatment in detail, and then makes the decision together with the patient.

For treatments like implants, inlays, and crowns, which are costly

and require multiple visits, trust is especially important.

For this reason, after the examination, I personally explain both the patient’s condition and the treatment method.

Even if it is familiar to us, it may be unfamiliar to patients.

So we need to present the symptoms and the reason for treatment in detail

and explain them in a way that patients can understand.

The reason molar cavity treatment costs differ from hospital to hospital is not simply because of overtreatment.

  1. Standards for identifying cavities

  2. The level of diagnostic equipment

  3. The choice of treatment method

  4. The type of material used

Various factors work together.

Then which dental clinic should you choose? The most important thing is to check whether it is a place that honestly explains only the treatments that are truly necessary.

A dental clinic that accurately diagnoses the patient’s tooth condition, and clearly explains why this treatment is needed.

And a clinic that starts treatment only after the patient understands and agrees. A place like that should be trustworthy.

Cavities are simpler to treat and cost less when they are found early.

That is why regular checkups are so important.

Visit the dentist once every 6 months to check whether cavities have developed, and if they have, receive early treatment.

If you leave them alone because there is no pain, you may later end up needing root canal treatment.

If that happens, the treatment period becomes longer and the cost increases several times over.
