Tooth Whitening Method, Effects, Principles, and Precautions Explained by a Dentist in Bongcheon-dong

Hello,

I’m Director Park Jeong-gi of Seoul Remember Dental Clinic in Bongcheon-dong.

When teeth feel sensitive or painful,

it is important to undergo examination and treatment,

but these days, as interest in beauty has increased,

patients seeking tooth whitening

have also increased significantly.

It is a convenient and fast procedure

that can make yellow-stained teeth

white and clean.

However, at this time, you must make sure

it is a place with extensive experience,

a place that uses genuine, properly measured products,

and a place where a professional performs the procedure directly.

Today at the Bongcheon-dong dental clinic,

we will look at a related case

and provide useful medical information.

1. First Visit

Looking inside the mouth,

the alignment is not bad,

but the overall color feels yellow and dark.

The average shade for Koreans is A3,

but the whiter and healthier the skin,

the darker and more yellow the teeth may appear in comparison.

That is why, when the alignment is excellent and the teeth are very even,

but only the color is dark,

whitening can produce satisfactory results

without removing any natural tooth structure at all.

2. Principle

At the Bongcheon-dong dental clinic,

to help with understanding,

let me first explain why teeth become darker.

The surface of a real natural tooth

is like rough basalt, with bumps and pits.

Because of this, depending on daily habits

such as beverages and foods,

staining can occur,

and factors such as smoking

cause pigments to become lodged in those spaces,

so teeth gradually turn more yellow.

3. Procedure

If you decide to proceed with whitening,

at the Bongcheon-dong dental clinic,

we use a shade guide

to check the exact shade.

Then we perform scaling to remove calculus,

and a polishing procedure to smooth the tooth surface.

No matter how good the product is,

if there is foreign material on the teeth to begin with

or if the procedure is done while calculus is still attached,

the result cannot be good.

After that, a dam (gum protector)

is applied to the gums, and the whitening agent is applied to the tooth surfaces.

If it has been carefully applied,

a dedicated light-curing device is used for about 15 to 20 minutes

to remove the color.

※ The time and number of sessions like this

can only be determined by the doctor

who examined the patient directly,

and may be limited

if side effects are expected.

Fortunately, in this case, the enamel was also thick,

and the patient had no discomfort during the procedure,

such as tooth sensitivity,

so we upgraded it to B1.

4. Result

2025.09.10

Unlike before, the color changed to a brighter and clearer tone,

and it matched the patient’s skin tone harmoniously.

The teeth that had felt especially yellow

must have been a long-standing complex,

so thinking that this has now been resolved

makes the Bongcheon-dong dental clinic feel very rewarding as well.

Because the alignment is fairly even,

even though the teeth only became a little brighter,

it may feel as if laminate veneers were placed.

Each person has different natural tooth color, hardness,

gum elasticity, and tooth-surface roughness.

Therefore, procedures like the tooth whitening

explained today

must be customized and performed safely

while considering each patient’s different oral condition.

Otherwise, problems such as tooth sensitivity,

uneven or blotchy marks,

and gum burns may occur.

To do this,

it is essential that a doctor directly

examines and consults with the patient before the procedure,

and

you should receive treatment at a place

with extensive experience in these procedures.

Thank you for reading.
