    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 ^^

    365 Dream Dental Hospital Tooth Whitening

    I applied for teeth whitening because the price was so affordable!! Before the procedure, I asked various questions, and I appreciate how politely all the doctors explained everything to me. Hehe. The hospital is clean, and I noticed there was a massage chair in the waiting area, so I got a massage while waiting. I want to continue coming here regularly.

    I went for scaling and had a whitening consultation, and since I had trust from reading reviews, I decided to proceed with the whitening. It was done on the same day, and my friends said it was painful, so I was a bit worried, but I didn't feel any pain at all. And the results are really great; my teeth became so white, it's amazing.

    Teeth Whitening in Just One Day

    I had teeth whitening done at Blanch Dental Clinic! I was really worried that my teeth would feel sensitive after getting braces since they became quite weak. I'm such a coward when it comes to dental treatments... I made a big fuss about it, haha! But the dentists here were so kind, I was surprised that a dental clinic could be this friendly????? They were the most considerate I've encountered! Haha, if you're a coward like me and want to go to a friendly clinic, this is the place for you!! The dental hygienists were all very kind, and especially Ms. Jimin was incredibly nice. She explained each part of the process and why I was experiencing sensitivity, which made me feel at ease, hehe!!! She is truly a gem...

    Teeth Whitening in Just One Day

    I made an appointment near my workplace for scaling and whitening, and I just came back, haha! I really like having white teeth, so I periodically get teeth whitening done, but having that mouth opener thing is always really embarrassing, right? Hahaha! But soon I'll have my white teeth, so you can just think about something else for the next hour^^ A few months ago, I got whitening done at another clinic, and it was so sensitive that I was thinking of not doing it again, but I recommend this place for those who are interested! It was a little sensitive when the gel was applied, but I was really impressed by how the nurse provided detailed care!

    It was a really busy clinic, but everyone was friendly. The prices were reasonable too. It may not be obvious in the photos, but my upper teeth have definitely become brighter.

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

    I was concerned about looking yellow when taking photos, so I tried self-whitening methods like whitening toothpaste and LED devices, but they had little effect. I finally decided to go for it, and after just two treatments, the difference is incredible, haha. It's not expensive for no reason. I wish I had done this earlier considering all the money and time I've spent on self-whitening...

    The one-day teeth whitening effect is great. My yellow teeth are getting brighter. I need to be careful with foods that stain my teeth.

    I need to get orthodontic treatment. I didn't take care of my teeth when I was younger, and now with my wisdom teeth coming in, they're a bit crooked, which stresses me outㅠㅠ I should definitely get my teeth beautifully aligned, have them whitened, and not delay regular scaling -!! Thank you for the friendly consultation hehehe
