The teeth whitening effect is good.

I have somewhat yellow teeth, so I have always had a complex about it. When I smile broadly, my yellow teeth are very visible, so I tend to keep my mouth closed when I smile. I also tried teeth whitening toothpaste and DIY teeth whitening products at home, but they didn't really work well.

So, I ended up going to the dentist for teeth whitening, and the conclusion is that I was very satisfied.

It's been about 17 years since I had teeth whitening, and I think I paid around 1 million won at that time. I believe I received the treatment twice, about a week apart.

After receiving it initially, I experienced some tingling sensations, but they improved over time. Even after 17 years, I still maintain a whiter state compared to before teeth whitening.

Of course, over the 17 years, I have also consumed coffee and various foods that stain teeth, so the color has changed somewhat since the teeth whitening procedure, but I am still satisfied with the color.

I think the prices might be similar or even cheaper now, but if you're someone concerned about yellowing teeth, I highly recommend going to the dentist for teeth whitening.
