    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 ^^

    One-Day Teeth Whitening (Special Trial Price)

    It’s a shame I couldn’t take before-and-after photos, but the difference is incredible!! I arrived at 11 and finished around 12:30. Most people say it feels sensitive, but I didn’t feel any sensitivity at all. It was a little uncomfortable because the mouth retractor was pressing on the area around my lower teeth, so it hurt throughout the procedure ㅠ Still, whenever I said it was hurting, the nurse kept placing cotton there for me, which I really appreciated.

    I kept worrying about teeth whitening and finally went for it. They applied some medication and used a laser light? It was a bit uncomfortable, but I'm satisfied with how white my teeth are.

    I tried using whitening toothpaste, but it didn't really help. Since my teeth were badly discolored, I couldn't smile widely and my self-esteem took a hit. However, the professional whitening made a noticeable difference; the yellow stains and dark spots got better. The hospital staff were also very kind, and the facilities were nice. Thank you.

    My teeth were originally fairly white, but recently I stopped drinking coffee and switched to black and green tea instead, which caused staining on my front teeth. The staining was especially noticeable along my canine teeth rather than my incisors, and it became a real insecurity for me. I wasn’t sure which dental clinic to go to, but Namcheon Dental Clinic had lots of reviews and good ratings, so I made an appointment and visited. Since it was my first visit, they took panoramic X-rays to check the overall condition of my teeth. I mentioned that I wanted to whiten my front teeth, so I had the whitening treatment done that same day. Before the whitening treatment, I had dental scaling, and I really appreciated how thoroughly the dental hygienist removed the tartar, even from the back of my molars. I had laser whitening after the pretreatment, but I didn’t experience any discomfort at all, such as pain or tooth sensitivity. The results were great too, and my teeth look much brighter now.

    I was really stressed out by my yellow teeth, and every time I looked in the mirror, it bothered me. So, I decided to get teeth whitening and looked into various dental clinics. I ended up going to Yonsei GD Dental Clinic because it's pain-friendly and convenient to get to. Even though it was my first visit, there were a lot of reserved patients. After checking in for my appointment, I had a consultation right away, where they explained my concerns and the procedure in detail. I had heard that teeth whitening can be pretty expensive and painful, and I was worried because there are many reviews saying the results don’t last long. Still, I really wanted to try it, so I went for the one-day teeth whitening. I had a total of 3 sessions, and it was great that it was all done in one day, and I'm really satisfied with the results.
