I had orthodontic treatment before, but after my braces were removed, my teeth became yellow, possibly because I drank coffee so often. I felt self-conscious when I smiled and was stressed about it, so I decided to get my teeth whitened. After looking into it online, I found out that one-day teeth whitening could brighten my teeth in just one day, so I went to Nuga Dental Clinic, which is close to my home. Before the treatment, I had a consultation with the dentist, who carefully checked the shade and condition of my teeth and explained how much brighter they could become. They applied gum protectant carefully, and then the treatment began. I had three 15-minute sessions, and I was happy that there was almost no pain. I'm satisfied because my teeth are much brighter now.

As I get older, my teeth seem to be getting yellow, which really upsets me. I thought if I got whitening, I could smile brightly too, so I went through the procedure and I'm satisfied with the results.

I visited to receive scaling and a one-day teeth whitening treatment. Since it was a weekday, I walked in without an appointment and was able to have a consultation and proceed with the whitening after about a 10-minute wait. Dr. Baek Won-sun personally conducted the consultation, which made me feel confident.

I've been thinking about getting teeth whitening for a while now and finally had a consultation, but the cost isn't as daunting as I expected.. I've heard that the whitening results are good, so I have to consider it.

I've always been someone who likes coffee, so my teeth weren't looking great. With my wedding coming up, I started to worry about the color of my teeth for the photos, and since there will be many photo opportunities in the future, I decided to go for teeth whitening. I searched for local dental clinics and found one that was conveniently located, Kim Tae-young Dental Clinic, and decided to go there for treatment. I had a consultation with the doctor, who explained the treatment process to me. First, I brushed my teeth, and then I was guided to the treatment area. Fortunately, there were no cavities, and the teeth whitening treatment didn't take as long as I expected, which was great, and my teeth definitely became whiter.

I tried using whitening toothpaste, but it didn't have much effect. My teeth were severely discolored, and I couldn't smile widely, losing my confidence. However, after professional whitening, the yellow discoloration and black stains improved significantly. My teeth felt a bit sensitive, but it got better in just a few days.
