Hello, this is Gangnam Leon Dental Clinic 😊
I wrote a post about cavities a little while ago.
Most people usually think of cavities as being black.
But did you know that cavities can also appear white?
This is an early symptom of tooth decay
that appears before the tooth turns black.
But does that mean every white spot is a cavity?
No!
Today, we will look at the causes of white spots on the surface of the teeth
and the available treatment methods!

Causes of White Spots
White spots that appear on the surface of the teeth
may be, as mentioned above,
a symptom of early tooth decay.
✅ They can occur when oral hygiene is inadequate.
However, white spots can also appear even when there is no tooth decay due to
✅ congenital factors, ✅ trauma,
✅ insufficient nutrients during development, or
✅ excessive fluoride exposure!
Because treatment varies depending on the cause,
an accurate diagnosis is important.

Cavities vs. White Spots
🦷 If the white spot is an early sign of tooth decay,
it is still at a stage before the tooth has begun to decay extensively.
With proper care or preventive treatment,
it is possible to prevent the cavity from becoming deeper.
However, if oral hygiene is not properly maintained,
the decay will gradually deepen and develop into the familiar appearance of a cavity.
🦷 If it is a simple white spot,
there is no major problem even without treatment
because it does not change over time.
However, if it appears on the surface of a front tooth,
it may be aesthetically bothersome,
so removal can be considered.
| Cavity | Category | Simple white spot |
|---|
| Becomes larger and turns black | Progression | No change |
| Pain as the cavity becomes deeper | Pain | No pain |
| Oral hygiene and preventive treatment required | Treatment | Not required |
Accurate Diagnosis with Qray
To provide treatment suited to each cause,
cavities and white spots must be accurately distinguished.
Gangnam Leon Dental Clinic
uses the Qray dental device to distinguish
cavities from simple white spots
and make an accurate diagnosis.
Before treatment, we use Qray to conduct a detailed analysis of oral issues,
identify the area, extent, and depth of the white spot,
and establish an appropriate treatment plan accordingly.
This eliminates unnecessary procedures and allows treatment to proceed appropriately.

White Spot on a Front Tooth—Is It a Cavity?
A patient visited us after noticing a white discoloration
on the surface of a front tooth.
They were worried that it might be a cavity,
but after undergoing a Qray examination,
the spot was fortunately diagnosed as simple tooth mottling.

White spots that are not cavities
do not cause significant functional problems,
so treatment is not necessary.
However, as mentioned above,
if they appear on highly visible front teeth,
removal can be considered.
In such cases, they can be removed with Icon resin
without cutting or damaging the tooth.

After removing the white spot with Icon resin,
the surface of the front tooth looked naturally smooth and clean.

When transparent Icon resin is infiltrated,
the white discoloration gradually becomes less noticeable.
Because no tooth reduction is required, anesthesia is not necessary,
and an immediate result can be seen on the same day.
It seems that many cases proceed from an inquiry to actual treatment.
Today, we looked at white spots on the teeth,
also known as tooth mottling.
Whether a white spot is a simple spot or a cavity
is difficult to determine with the naked eye.
For an accurate diagnosis and appropriate treatment,
Gangnam Leon Dental Clinic
uses a Qray device.
