    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 heard my friend was extremely satisfied with the teeth whitening, so I looked around and chose this dental clinic to get it done. I'm totally relieved about my teeth now, amazing... With my wedding coming up, I've been extremely anxious and skeptical about many things, so I was really worried, but they explained the precautions thoroughly, and I didn't experience any pain or sensitivity, so I had a very comfortable experience. Thank you so much!!

    Myeongdong Combi Dental Teeth Whitening 3 sessions for 240,000 won

    I received scaling and teeth whitening. The procedure consisted of a total of 3 sessions (2 sessions during the initial visit + 1 session 10 days later), and immediately after the treatment, I definitely felt that my teeth were about 2 shades brighter. However, after eating, the color reverted somewhat to the previous shade, so I think it became about 1 shade brighter overall. Nevertheless, I had always been self-conscious about my tooth color, and seeing the results, I would recommend it. The procedure was performed by the nursing staff, and the doctor conducted a general examination to check if there were any damaged teeth. I remember that each session took less than 15 minutes. Overall, all the staff and medical personnel were very friendly, and the building looked new with excellent facilities. The waiting time was also not too long, around 10 minutes?

    I was really worried about my yellowing teeth. One-day teeth whitening works well. I should also avoid foods that stain teeth easily.

    The Yellow Teeth Escape Project caught my interest right from its name, and it has great results. I went because I heard it's a well-known place, and my discolored yellow teeth have become significantly whiter after the teeth whitening treatment. I experienced almost no sensitivity after the whitening, just a slight cold sensation. Post-whitening care is even more important.
