Why do white spots appear on front teeth? : Causes of spotted teeth

When this white stain, also called a white spot or white spot lesion, appears on the tooth surface,

✅ The tooth’s unique healthy shine disappears

✅ Aesthetic confidence in social interactions decreases

Above all,

✅ Because there is a possibility that it may progress into a cavity,

it is recommended to get an examination even if there is no particular pain.

There are several reasons why white spots appear:

1️⃣ Congenital causes

During the process of tooth formation,

it can occur congenitally due to enamel hypoplasia.

2️⃣ Tooth trauma

If the tooth is damaged due to external impact,

stains may appear on the surface.

3️⃣ Excess fluoride intake

White spot lesions can also occur when too much fluoride is consumed. Fluoride helps prevent cavities, but it is important to use an appropriate amount.

4️⃣ Early cavity signal

As the stage before a cavity, when the enamel surface begins to erode, a white spot may appear. If this worsens, it can turn into the brown or dark-colored cavity we know. If the progression of decay has stopped, it may remain in the form of a white spot lesion.

Case of front-teeth white spot removal : ICON resin

There are white and brown stains on the front teeth.. Do the teeth need to be shaved down?

Along with the white spots on both front teeth,

on the right side, the brown discoloration has spread from the front teeth to the canine.

The patient visited because they thought it might be a stain that could be removed by brushing, but it did not come off even after brushing.

In the past, the area would be shaved down to a depth where the stain was no longer visible, or covered with veneers to improve the appearance. With ICON resin, non-invasive treatment is possible without shaving the tooth down.

Detailed examination / accurate diagnosis using Qray

This is a new medical technology that shines harmless blue visible light into the mouth and detects areas with biofilm, then classifies them as red fluorescence through a special filter for diagnostic testing.

With excellent visual effect, it can precisely diagnose tooth decay, tooth fractures, plaque, tartar, and other tooth-related diseases and problems, and help establish an appropriate treatment plan.

After checking the extent and size of the white spot through Qray, if it is determined that treatment with ICON resin is possible, proceed to the next step.

Surface preparation through etching

Before ICON resin, we perform etching on the tooth surface. This helps ICON resin penetrate well into the demineralized enamel, where minerals have been lost, so that it can be filled in.

Applying ICON resin

Apply ICON resin to the enamel after surface preparation. The key is to apply it several times in thin layers, rather than in a large amount all at once. That way, it can penetrate well into the empty spaces in the enamel, so the white spot gradually becomes lighter and changes to a natural tooth color.

Finishing up

ICON resin treatment takes about 1 hour including the examination, and all procedures are performed without separate anesthesia. The noticeable white spots were cleanly removed in just one day.

One to two weeks later, we additionally performed tooth whitening to complete the treatment. If you also want tooth whitening, it is more effective to leave some time between treatments so that the ICON resin can sufficiently penetrate and settle, rather than doing it on the same day as the ICON resin procedure.

Can I get ICON resin? Just because there are white spots on the tooth surface, does not mean everyone is a candidate for ICON resin.

🟢Treatable🟢

✔ Early-stage cavities

✔ Internal micro-demineralization progressing due to various causes

Therefore, after examination, whether ICON resin treatment is possible is determined, and if not, other appropriate treatment suited to the cause is performed.

🔴Difficult to treat🔴

✔ Enamel chipping

✔ Cavity progression reaching the dentin

✔ Areas that have already received resin treatment in the past

In these cases, ICON resin treatment may be difficult to apply or its effect may be limited, so existing cavity treatment or another treatment is needed.

White spots that did not come off even with brushing or tooth whitening. Through an examination, they can be improved in one day with ICON resin.

Depending on the size and progression of the white spot, we can determine whether ICON resin is possible and treat it without burden, so if you have any questions or concerns, please feel free to get a consultation.
