    Myeongdong Dental Clinic30-Minute Complete Teeth Whitening Program

    Because I had orthodontic treatment and drank a lot of coffee, my teeth had become yellow, so I wanted to get teeth whitening. While looking into where to have it done, I found it through Eodiseo, and the reviews were good, so I requested a consultation, made an appointment, and visited. I had three treatments and am very satisfied. I had the first and second sessions done at once on the first day, and the third session a week later. I’m also glad that I didn’t experience any sensitivity.

    They were very kind. Before getting the treatment, I wasn’t sure if it would really work, but I had three sessions in total. I had the second session about two and a half weeks after the first, and it really was effective. The sensitivity may vary from person to person, but mine only lasted for a short while. I’m satisfied!! The photos were taken before the second session and after the third session.

    I had one session, and it has brightened a bit. I've been busy with work and couldn't have the second treatment, but I'm planning to schedule it again in the new year ^^

    I've always been concerned about the color of my teeth when I looked in the mirror. I wanted to get teeth whitening treatment, but I kept putting it off because I thought it would be painful and uncomfortable. However, I figured it would be better than continuing to stress about it, so I searched for reviews and went to Yonsei Tis Dental Clinic. I first had a consultation with the doctor, who explained the process and principles of the treatment. I underwent the whitening procedure and they applied the whitening gel. Contrary to what I had worried about, there was no sensitivity in my teeth during the treatment, which was great. After the whitening session, when I looked in the mirror, my teeth were definitely looking cleaner. Whitening usually isn't finished in one go, so I decided to receive the treatment again in six months.

The treatment process was less uncomfortable than I expected, and I was able to go through it comfortably. They also explained clearly how everything would proceed before and after the treatment, so I felt reassured.
