City Hall Station One-Day Teeth Whitening: The Dental Clinic with the Most Whitening Sessions in Jung-gu, Including Costs and Prices—Teeth Whitening for Wedding Preparation

Hello.

This is Yonsei Yegam Dental Clinic, located in the heart of Seoul, at City Hall Station.

We are a dental clinic well known for teeth whitening.

We are a 3-minute walk from Exit 7 of Seoul City Hall Station, directly across from the Samsung Main Building.

We are also easily accessible from Myeongdong, Euljiro, Seodaemun Station, Mapo, Seoul Station, and Gwanghwamun.

Today, we would like to introduce teeth whitening, a procedure performed far more frequently at our Yonsei Yegam Dental Clinic at City Hall Station than at other dental clinics.

Let’s escape yellowish teeth!

Since most dental clinics generally focus on treatments such as cavity care, they do not often provide teeth whitening.

In addition, whitening is a type of treatment for which VAT must legally be charged. Therefore, dental clinics registered not to collect VAT do not provide whitening. Because of this restriction, many dental clinics do not offer whitening.

Our Yonsei Yegam Dental Clinic provides plenty of cavity and gum treatments as well, but we perform significantly more whitening than other dental clinics, which has made us well known for teeth whitening.

This is because the clinic has become a destination where foreign tourists come specifically to receive whitening.

Just as getting a massage is popular when visiting certain countries in Asia, our dental clinic has become a destination that visitors to Korea seek out for teeth whitening because of its whitening results.

Even teeth with a significantly dark shade like this were whitened in one day, becoming much brighter.

Reasons to receive teeth whitening at Yonsei Yegam Dental Clinic at City Hall Station

• The dental clinic that performs the most teeth whitening in Seoul’s Jung-gu. Foreign tourists from around the world also make special visits here for whitening.

• Whitening specialist: Before Osstem, Korea’s No. 1 dental brand, released its whitening product, the director visited the Osstem factory in the winter of 2013, observed the whitening-agent development process, and participated in a demonstration!

• The most suitable whitening agent and pre-treatment: We have tested various products to determine which ones are best, and use only the most effective products, even if they are expensive. I also remember a dental hygienist who had worked at another dental clinic seeing how generously we applied the whitening agent and commenting that it was exceptionally generous. The thickness of the whitening-agent application is important, too!

Yonsei Yegam Dental Clinic’s whitening lights

Four whitening lights, even though they are said to be expensive???

Unlike most dental clinics, which have only one whitening light, we have a total of four.

We have tested all of them and use only the whitening light that produces the best results.

Important points to check regarding teeth whitening

1. A pre-whitening examination is essential. You should receive teeth whitening only after checking whether your teeth are in a condition suitable for whitening. This allows you to undergo whitening without significant sensitivity or major side effects.

2. Teeth whitening is a time-consuming treatment. Even after applying gum-protection gel and the whitening agent, time is needed for light exposure. Therefore, please allow about one and a half hours for two one-day whitening sessions and about two hours for three one-day whitening sessions.

3. For two hours after teeth whitening, do not consume anything other than water. To maintain the results for as long as possible, it is best to continue avoiding foods that cause staining whenever possible.

Whitening takes considerable time, including the examination, application of the gum-protection gel, application of the whitening agent, and light exposure, so an appointment is required.

Because the pre-treatment process for teeth whitening is complex and lengthy, please allow at least 1.5 hours and approximately 2 hours for three one-day sessions, and at least 1 hour and approximately 1.5 hours for two one-day sessions.

In the morning, 11:30 a.m. is the last appointment time for whitening; in the afternoon, the last appointment time is 5 p.m.

On Saturdays, the last appointment time for whitening is 12 p.m. (An appointment is required for teeth whitening.)

(We do not offer one-session one-day whitening.)

Caution: For two hours after whitening, do not eat or drink anything other than water. Please keep this in mind!

Perform a self-check to see whether your teeth are truly suitable for whitening.
