Hello,

I am the director of Seoul Bardi Dental Clinic.

"A black spot appeared between my front teeth,

and before I knew it, it spread this much."

When I see patients who come in feeling upset while looking in the mirror, I really feel for them as well.

When cavities develop in multiple teeth all at once, in dentistry we call this "multiple caries."

This is more than just an appearance issue; it is also a sign that can threaten both the nerve and the lifespan of your valuable teeth.

Many people visit us worrying, "Isn't it too late?" but please do not be afraid too soon.

If it is diagnosed accurately and treated step by step, it can recover to health without needing extraction.

Today, I will share the story of how we restored six blackened front teeth beautifully again with root canal treatment and zirconia.

I hope this post brings even a little reassurance to those with similar concerns.

Multiple front-tooth cavities that appear all at once, how are they treated? A single black spot of decay between the front teeth may be a warning sign of multiple cavities.

Cavities usually develop because care has been a little neglected, because of a habit of enjoying sweet foods,

or because the mouth frequently becomes dry.

Treatment methods vary depending on how deep the cavity is.

  1. Early stage

If the cavity area is small, only that part can be cleaned out and simply filled with tooth-colored resin.

  1. Mid-stage

If the cavity is deep and has reached near the nerve, root canal treatment must be performed as well,

and a crown that protects the entire tooth should be placed.

  1. Advanced stage

If the root is too severely damaged, unfortunately the tooth may need to be extracted and an implant considered.

A case of multiple caries between the teeth, reconstructed with zirconia crowns A single black spot of decay between the front teeth may be a warning sign of multiple cavities.

A patient who recently visited our clinic had fairly deep cavities progressing between the front teeth.

The dark visible area was quite large,

especially around #11 and #21, the central incisors, where the decay had reached the nerve,

so they had been struggling with a lot of pain.

If they had come just a little earlier, it might have ended with a simple filling, and that was somewhat regrettable,

but at this point, protecting the teeth firmly was the priority, so for the central incisors (#11, 12) we performed root canal treatment first,

and then decided to cover the six front teeth (#13~23) with zirconia.

"0.1 mm detail" made by our in-house dental lab A single black spot of decay between the front teeth may be a warning sign of multiple cavities.

The front teeth can look completely different with even the smallest 0.1 mm difference in shape.

So instead of sending the work to an outside lab, we use our in-house dental lab located inside the clinic,

and I communicate directly with the lab manager to create the prosthetics.

Only by seeing the patient’s face in person and adjusting the angle and translucency of the teeth one by one

can we achieve a natural result that truly feels like "my own teeth." ^^

Having an in-house dental lab also makes the treatment process much smoother.

Even for a large treatment area like six front teeth, as in this case, we were able to make temporary teeth on the same day,

so the patient could return immediately without disruption to daily life.

In particular, while using the temporary teeth,

"I want the shape to be a little rounder" or "I wish the length were just a bit shorter"

specific requests like these can be reflected on the spot.

That is the secret to making much more precise adjustments than communicating with an outside lab only through documents.

For this patient as well, we reflected the feedback given at the temporary tooth stage in the final prosthetics exactly as requested,

and were able to complete prosthetics that the patient was truly satisfied with. ^^

Why we made individual crowns instead of a bridge A single black spot of decay between the front teeth may be a warning sign of multiple cavities.

Usually, when treating six front teeth all at once, many people imagine a single long, connected "bridge" shape.

But we carefully made each tooth separately and covered them individually.

That way, if a problem should arise with just one tooth later,

we do not need to remove everything; we can treat only that part separately.

An example of reducing treatment cost burden through private dental insurance A single black spot of decay between the front teeth may be a warning sign of multiple cavities.

As the number of teeth requiring treatment increases, cost worries are naturally the first thing on your mind.

Because we understand how patients feel, we carefully handle the insurance benefits they can receive as if it were our own matter.

In fact, each insurance company has different required disease codes, and the paperwork is quite complicated,

so it is often daunting for patients to prepare everything themselves.

For this patient as well, after carefully checking the insurance they had signed up for,

fortunately, the policy covered three crown treatments per year and root canal treatment.

So, to ensure that not a single item would be missed in the reimbursement process,

we also prepared all the evidence documents required by the insurance company.

As a result, the patient was able to greatly reduce the burden of what could have been a stressful treatment cost and finish treatment with peace of mind.^^

Front-tooth cavities take away not only your comfort, but also your confidence in your smile.

But please do not become too discouraged, thinking it is already too late.

If there is an accurate diagnosis and a detailed plan, you can fully regain a healthy and attractive smile.

If you have been worrying alone because of the blackened cavities you see every time you look in the mirror, please visit us with ease.

We will think together about the method that you can use most comfortably and for the longest time from the patient's perspective.

Thank you. ^^
