Hello.
Say exactly what needs to be said, with minimal burden
This is Seoul Dia Dental Clinic at Magok Station.
Today, we have prepared the final part of the Dianate no-prep laminate series,
Episode 4, the “peg lateral case.”
We previously covered gaps between the front teeth, chipped front teeth, and resin discoloration,
and the last topic is a problem many people quietly worry about but find hard to talk about:
a peg lateral tooth.
A peg lateral may be small, but its presence is very noticeable.
Especially when it occurs in the lateral incisor next to the upper front teeth,
it can make the smile line look off in an instant.
So today, from the characteristics of a peg lateral to treatment methods,
and this case itself, let’s take a look in the style of Seoul Dia Dental Clinic at Magok Station.
Peg lateral teeth may be small,
but the concern is never small

A peg lateral tooth is smaller than a normal-sized tooth,
and it appears most commonly in the lateral incisor
(the tooth right next to the upper front tooth).
If one of the parents has peg lateral teeth,
the likelihood of a similar shape appearing is higher,
and it can occur when the tooth germ does not develop sufficiently
during the stage when the tooth is formed.
It may look small and pointed,
or the size difference from the adjacent tooth may be so large that when smiling,
people’s eyes are naturally drawn to that area.
This is what patients say most often:
“Those two are so small that they keep standing out.”
“In photos, the front teeth look okay, but the sides look empty.”
The aesthetic stress is much greater than the functional issue.
Even two small teeth can make the entire smile look different.
Treatment options for peg lateral teeth,
what choices are there?
- Aesthetic resin (Composite Resin)

It has the advantages of being fast,
cost-effective,
and easy to adjust in shape.
However, it discolors quickly,
is difficult to keep glossy,
and the margins become noticeable over time.
In particular, in areas like the front teeth where light reflection is important,
there may be procedural limitations.
In other words, a “quick fix” is possible,
but “long-lasting naturalness” may be lacking.
- Crown (all-ceramic / zirconia)

Because it covers the entire tooth, it is very strong
and excellent at correcting shape.
It is chosen when root canal treatment has been done or when the tooth is very small.
However, it requires tooth reduction,
and it can feel burdensome if chosen purely for aesthetic purposes.
That is why crowns are used in cases where structural reinforcement is needed.
- Dianate (no-prep laminate)

Because peg lateral teeth are small,
even a little design refinement can dramatically change the entire smile.
That is why Dianate fits them so well.
With almost no tooth reduction,
it does not make a small tooth look like it suddenly became a big tooth;
rather, it can be enlarged naturally so it looks like it was always that size,
and it expresses color, translucency, and gloss almost identically to natural teeth.
Once a small tooth is changed,
you can see the moment when the smile line is completely organized.
A real peg lateral Dianate case
- Patient concern

“Those two teeth on the sides are so small that I keep looking at them.”
The concern is that only that area keeps showing up in photos.
- Design direction

Magok Station Dianate design
For a peg lateral, the key is making it look like it was “always there.”
So the treatment direction was designed like this.
A feeling that it has “always been this size”
- Adjust symmetry so the upper and lower teeth look balanced when smiling
When it is completed, the result is a design that does not stand out yet changes the overall impression.
- Result

The patient’s first words after treatment are usually similar.
“Uh… this really looks like my original tooth!”
And the actual changes are as follows.
-
Natural appearance with almost no visible margin, even up close
-
The smile line comes alive, softening the overall facial impression
-
The habit of covering the front teeth when taking photos disappears
-
Color and gloss remain natural, even in natural light
Just two small teeth changed,
yet the entire smile comes alive—
this is where the strength of Dianate shines most clearly in peg lateral cases.
Today’s key summary
-
Peg lateral teeth commonly occur in the lateral incisor next to the upper front teeth
-
The biggest feature is aesthetic stress
-
Treatment options include resin, crown, and Dianate
-
Based on naturalness, minimal reduction, light reflection, and durability,
Dianate is the most advantageous
Because of its nature,
peg lateral teeth are an area that absolutely requires delicate design, accurate analysis,
and experienced hands.
