    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 often drink coffee, which may be why my teeth have gradually become yellowish, and I've been quite troubled by it. I wanted to resolve it before an important event, so I received a teeth whitening treatment at Rev Dental. The procedure was brief, lasting 1 to 2 hours a day. I felt reassured that it was a professional whitening done at the dental clinic. After the treatment, the yellowish discoloration improved significantly. I wasn't expecting much since I heard the teeth could get at least two shades brighter after the procedure, but I was pleasantly surprised with the result. I gained a boost in confidence when I smiled. The effect lasts about 1 to 2 years, but I need to be careful with foods and drinks that can stain my teeth, like coffee.
