Dental Clinic at Seoul National University Entrance Station: The Start of Year-End Event Prep Is One-Day Teeth Whitening

Treatment date: 2025.11.20

Hello,

I’m Director Park Jeong-gi of Remember Dental Clinic at Seoul National University Entrance Station.

Now that autumn is passing and winter is settling in,

As the year-end gets closer, there are probably more gatherings and events,

and when people meet in groups, they smile brightly and take a group photo,

and while catching up with acquaintances whom they haven’t seen in a long time, they end up chatting until their mouths go dry.

Because of that, before the year ends, more patients seem to be looking for teeth whitening.

Today at the dental clinic at Seoul National University Entrance Station, I’ll look at a related case and explain a few pieces of useful general knowledge.

1. My teeth look yellow overall.

Looking at the initial clinical photo, this patient has a shade around B1.

The average shade for Koreans is around A3, so B1 is not that dark.

However, each person has a different standard for what they consider white, and depending on their skin tone or makeup style, they may perceive color differently.

That is why, even in today’s case, although the shade is not particularly dark, the patient still wanted teeth whitening.

It also seems to be something many people seek before events such as weddings or a child’s first birthday party.

2. Setting a baseline with a shade guide

At the dental clinic at Seoul National University Entrance Station, as mentioned earlier, because everyone has a different standard of beauty, we check the tooth shade before treatment using a shade guide.

By comparing the patient’s current color with this step-by-step shade guide, we can check in advance the closest matching shade,

and after treatment, we can also show how much brighter the teeth became.

3. The importance of examination before treatment

At the dental clinic at Seoul National University Entrance Station, once we decide to proceed with teeth whitening, we start with a thorough examination by the attending doctor.

This is because the doctor determines how sensitive the teeth are when air is blown on them, and how thick the enamel is,

which helps decide how many times, and for how many minutes, the whitening agent should be applied.

The degree of brightness changes depending on these cycles, and the more cycles are repeated, the whiter the teeth become.

★ However, if orthodontic appliances are attached or if restorations such as crowns are present, there are limits to how much those areas can be whitened even if the cycles are repeated many times. So this must be taken into account beforehand.

Also, if the procedure is performed for too long or too many times in an excessive manner, sensitivity may increase and tooth sensitivity may occur, so you must be sure to consult the doctor in charge beforehand.

In addition, if there is a lot of plaque buildup, scaling should be performed first, and if there is tooth decay, the cavity should be treated before whitening.

4. Treatment results

Let’s take a look at the result after completing one-day teeth whitening at the dental clinic at Seoul National University Entrance Station.

To check how much brighter the teeth became, we compared them closely with the initial shade of B1 that the patient had at the first visit, and it is clearly noticeable that they became brighter.

It is likely around A1.

Also, because we proceeded after scaling to keep the tooth surfaces clean, the result finished evenly and white without blotches.

If the tooth surfaces had not been thoroughly cleaned, they might have turned whitish and irregular, but fortunately it was completed well.

Considering the busy year-end season, we performed the treatment in one day as a one-day procedure, so the patient’s satisfaction with how quickly it was completed must have been very high.

The teeth whitening explained today at the dental clinic at Seoul National University Entrance Station is a good way to create a dramatic change for people who want brighter, whiter teeth.

However, before the procedure, be sure to consult with the specialist in charge, check the cycle that is right for you and the condition of your teeth, and proceed safely.

Thank you for reading.
