Interproximal Front-Tooth Cavities Can Even Create a Tooth-Shaping Effect with Resin

I had a filling between my front teeth before,

and every time I smile,

it looks like something is stuck there..

And my front teeth stick out too much,

like rabbit teeth.

Interproximal front-tooth cavity

The patient had already been treated at another dental clinic for an interproximal cavity between the front teeth with resin.

This patient originally came to our clinic for scaling, and later also received TMJ treatment and continued regular gum treatment.

One day, while receiving treatment, they carefully brought up their concerns about their front teethㅎㅎ

The real reason the space looked dark Interproximal front-tooth cavity

When I looked closely at the front teeth, over time the resin color had become slightly darker than the surrounding teeth, and the boundary between the teeth was not smooth, so the area looked a little dark.

In cases like this, adding more resin on top does not solve the problem. It can actually make the area thicker and more noticeable.

So the existing resin needs to be completely removed first, and the space cleaned up neatly.

It is always much more important to think about “how far to clean up” than “how much to fill.”

One more thing caught my eye.

One front tooth was slightly set back, creating a height difference.

This is why it felt like the teeth were sticking out like rabbit teeth.

So for this treatment, we designed the front surface with a thin layer of resin to make the whole area look like one flat plane.

Rather than making the teeth larger, we planned it in a way that made them appear visually smaller and more even.

The part where the front teeth are different in length needs reshaping.

The ends of the teeth were different lengths on each side, so they probably felt less even.

When I mentioned that the lengths were different, the patient said, 'I didn't know that.'

For a neat shape, we decided to match the lengths.

Between front teeth, being too perfect can actually look unnatural. Interproximal front-tooth cavity

There is a request I often hear in front-tooth treatment: “Please close the gap completely.”

But if that space is closed too perfectly, the teeth can look bulky, or floss may not go through, making maintenance more difficult and potentially harming gum health.

In this treatment, we decided to remove the height difference that looked dark when smiling,

but leave just a slight amount of space between the teeth. Interproximal front-tooth cavity

That amount of space can naturally be filled in by the gums over time, and above all, it is less noticeable and helps maintain gum health.

This is how the treatment was done. Interproximal front-tooth cavity

First, we carefully removed the existing resin and decay.

The important part here was to remove only the resin precisely without touching the tooth itself.

After that, we kept comparing the shape and angle of the two front teeth. From the front, from the side, and even the position covered by the lips when speaking.

One front tooth was slightly set back, so we corrected only the front surface with resin there.

If too much is added, it will look protruded; if too little is added, the height difference remains. So a very small adjustment really mattersㅎㅎ

When filling the space between the front teeth, we did not fill it all at once; instead, we shaped it in small sections.

That way, the teeth do not look dull, and the light reflects naturally.

No anesthesia was used, and we kept checking with the patient throughout to see whether the sensation was comfortable.

Front-tooth treatment is not something a doctor completes alone; it is a process created together with the patient.

The final step is the expression in the mirror. Interproximal front-tooth cavity

Once everything was finished, I always hand the patient a mirror first.

This time too, the patient smiled as soon as they looked in the mirrorㅎㅎ After a brief pause, they said:

"Now I won't have to worry when I smile. If I had known it would turn out this pretty, I should have told you sooner~"

In front-tooth treatment, the moment the patient smiles is more important than the moment the doctor feels satisfied.

So I checked everything to the end—whether the height was okay, whether there was any catching sensation when speaking, and whether there was even the slightest awkwardness—then finished with fine adjustments.^^

Even if interproximal front-tooth decay looks small,

it can change a person’s impression quite a lot.

This treatment was a case showing that a difference of just a tiny detail can change someone’s impression.

I will be giving lectures to dentists in January and February next year.

To put it simply, it will be a time to share the cases I treated under the theme of reducing tooth reduction and preserving teethㅎㅎ

I feel happy and grateful that the time I have spent maintaining my treatment philosophy is being recognized🙏🏻🥹

Going forward, I will continue helping preserve many patients’ teeth so that front teeth stay beautiful and well aligned, and molars can chew comfortably.
