Hello, this is Gangnam León Dental Clinic😊

A white spot that suddenly appears on a child's front tooth!

At first, it may seem like a simple stain,

but it could be a sign that a cavity is starting.

Today, along with the early symptoms of pediatric cavities,

we'll look into the principles and process of ICON resin,

a non-invasive treatment method!

Pediatric cavities

Children's teeth have thinner enamel and dentin

and contain fewer minerals,

so demineralization caused by acid occurs easily.

For this reason, they tend to progress faster than in adults.

Therefore, it is important to detect cavity symptoms early

and receive appropriate treatment.

In particular, white spots that appear on front teeth

may, depending on the case, not be simple discoloration

but an early sign of tooth decay

that can lead to cavities.

Early signs of tooth decay:

white spots

Usually, many people miss the early cavity signal

and come in for treatment only after finding black cavities

visible to the naked eye.

This is because early signals of tooth decay

can be difficult to identify with the naked eye.

✔️ White spots on front teeth or molars

✔️ A dull, rough surface

✔️ Stains that do not come off with brushing

In fact, not all white spots

require treatment.

In particular, if it is very early tooth decay or

simply a spot caused by a weak tooth surface structure,

then unless it is causing aesthetic concern,

treatment does not necessarily have to be performed.

✅ Fluorosis

✅ Nutrient deficiency

✅ Simple demineralization

However, most white-spot symptoms

are a sign that the tooth surface has weakened,

and this is not merely a cosmetic issue,

but a structural change that can lead to demineralization by bacteria.

If the timing is missed,

the decay can progress deeper and turn into the black cavity we know.

Therefore, for an accurate assessment,

it is best to visit a dental clinic

and get an examination.

Treatment for white spots on children's front teeth:

ICON resin

ICON resin is a non-invasive treatment material

used to remove white spots.

Before ICON resin treatment, first

for an accurate treatment plan,

the extent of the white spot is assessed

with Qray before proceeding.

1️⃣ Treatment planning using Qray

Using Qray, you can check the degree and

range of demineralization in the tooth,

which allows for a more accurate treatment plan.

2️⃣ Tooth surface preparation

Before applying ICON resin to the affected area,

impurities on the tooth surface are removed,

and the surface is prepared so that

ICON resin can penetrate evenly.

3️⃣ Applying ICON resin

ICON resin is applied several times to the

prepared white-spot area.

When should you visit the dentist?

In the following cases,

it is a good idea to visit a dental clinic for a consultation.

✔️ If the white spot seems to be spreading

✔️ If the child feels discomfort in a specific area or

shows sensitivity when brushing

✔️ If the spot gradually changes to brown or black

If these symptoms are detected early,

before the cavity gets deeper, the child's psychological burden can be reduced,

and treatment can be performed non-invasively

so the tooth can be preserved.
