Hello, this is Seoul Ob Dental Hospital 💚
Today, we’d like to share the story of a male patient in his 20s who first came to us through a teeth whitening event and later went on to receive no-prep laminates (ObZero).
These days, many men are paying close attention to first impressions and appearance management as well.
Not only skin and hair, but also the clean impression created by bright, even teeth can’t be overlooked.
This case may be helpful for anyone interested in that kind of natural change!
📍At first, he was thinking of “just whitening”
This patient first visited our clinic through our teeth whitening event.
At the time, his tooth shade was around A3, and after whitening it naturally brightened to A1 😊

Satisfied with the results, the patient visited again two months later and underwent additional whitening.
As the tooth tone became brighter, his impression looked much clearer and healthier.
🦷 The two front teeth that were interfering with his smile
On his second visit, during the whitening consultation, the noticeable part was the size of the #12 and #22 teeth, which are the teeth on either side of the front teeth.
Both teeth were peg lateral incisors, making them look smaller and less refined than the adjacent teeth.
💬 Patient request: “Please make them look similar to the adjacent teeth”
The patient said he felt uncomfortable with a treatment that stood out too much and wanted only a natural-looking improvement.
So we recommended Seoul Ob Dental Hospital’s no-prep laminate brand, 'ObZero'.
ObZero is a procedure that uses very little tooth reduction and layers thin laminates over the teeth, helping create harmony in shape and color without damaging the natural teeth.
