Hello. This is Lucid Dental Clinic.

It is said that a person’s first impression is decided in just a few seconds.

Among the many factors, the brightness and cleanliness of the teeth

make a smile stand out and help the overall image

look more refined.

However carefully you brush your teeth,

tooth staining tends to build up little by little

from small habits in everyday life.

Beverages we enjoy, such as coffee, wine, and tea,

as well as the natural aging process, can gradually

dull the original color of the teeth.

A white, natural tooth tone is not just about appearance;

it becomes the starting point for a clean impression and

a sense of confidence you give yourself.

Today, we’d like to talk about the teeth whitening procedure

performed at the Seocho-dong Dental Clinic.

If you want to safely and naturally regain a bright smile,

this will be very helpful, so please stay with us until the end.

What is teeth whitening?

Teeth whitening is a procedure that professionally removes

pigments and discoloration deposited on the teeth to restore

their clear, natural tooth tone.

Unlike care that only cleans the surface, it acts on the deeper

layers inside the teeth, helping you regain a bright and clear look.

Because it is performed in a way that does not damage the tooth structure,

you can expect an image-improving effect while maintaining healthy teeth.

What causes tooth discoloration?

There are many different causes of tooth discoloration.

It is not simply due to poor brushing.

Common causes include the following.

Consumption of dark-colored drinks such as coffee, black tea, and wine

Pigments adhere to the tooth surface or seep inside

Smoking

Tar ingredients cause staining on the teeth

Consumption of sweets and foods that stain easily

Plaque builds up and causes pigment deposition

Aging

As you get older, the enamel becomes thinner,

and the color of the inner dentin may show through, making teeth appear more yellow

Depending on lifestyle habits, age, and health condition,

a change in tooth color can happen to anyone, so

don’t give up and think, “My teeth are just naturally yellow.”

With proper whitening care, improvement is fully possible.

Teeth whitening, number of sessions

The number of whitening sessions varies depending on each person’s tooth condition

and the desired level of brightness.

In general, noticeable improvement can be expected after about 1–3 sessions.

However, because results differ depending on the original tooth color,

the degree of staining, and lifestyle habits, it is important to

set up a personalized plan after an accurate consultation.

Points to note

Whitening is more effective when regular maintenance care is combined,

rather than being treated as a one-time procedure.

In particular, if you frequently drink coffee or wine,

or smoke, periodic Seocho-dong Dental Clinic care is necessary.
