    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 got my teeth whitened because I’m preparing for a job interview and planning to take a new ID photo~~~ Since you end up using an ID photo for quite a long time once you take it, it’s something you can’t help but worry about a little. I tried whitening my teeth at home but didn’t see much of a result, so I decided to come in for professional whitening!! The dentist also checked my teeth and gave me personalized advice based on their condition, which was great!! I heard a lot of people get their teeth whitened before taking ID or profile photos these days, and I’m really glad I did it >.<!!

    I just had teeth whitening treatment. The doctor was very kind and explained the precautions in detail. I especially trusted the whitening product since it was certified by the Ministry of Food and Drug Safety. The facility was clean and the location was convenient, so I recommend it.

    I got my teeth whitened! I come here every time I get teeth whitening. It’s affordable, and since they’re professionals, the results are definitely noticeable! They showed me this sample, and my teeth really got two or three shades whiter. People around me kept asking why my teeth had gotten so white, so it’s a treatment I make sure to get regularly.
