I always thought of the dentist as a difficult and painful place, but the doctors and nurses were so kind and helpful that I was able to receive treatment with peace of mind.~ Especially, they explained all my questions before and after the surgery thoroughly, and the head doctor kindly explained the progress during the surgery, so I didn't feel any pain and finished in a very comfortable atmosphere. I think I made a great choice by selecting Yonsei Good Day Dental Clinic~ I highly recommend it for those who are anxious~

As a partner hospital of Gangnam Severance Hospital, it is trustworthy and features specialists from various departments for integrated care. In my case, I had the opportunity to meet with both the orthodontics and conservational dentistry specialists for a consultation regarding collaborative treatment, which I found beneficial. The hospital is quite popular, so the waiting time was a bit long.

We are grateful that you trusted us with your visit, and we appreciate your thoughtful review. To ensure COVID-19 safety, we disinfect the chair after each patient's appointment, which may result in a slightly longer wait time. We kindly ask for your understanding. We will continue to provide sincere service for your remaining treatments~^^

I have been looking for hospitals that can provide treatment for molar root inflammation regardless of the location, and I visited after receiving recommendations from acquaintances and online communities. There are specialized doctors from university hospitals in various fields, and they provide kind and attentive care, ensuring patients feel safe and comfortable while receiving excellent treatment. The treatment is done well, and all the staff are friendly, so I am really satisfied and plan to continue regular check-ups even after completing the remaining treatment.

The corner of my molar has chipped off. I have a crown, and I would like to know how much it would cost to get a gold implant for it, as I’m having issues with the three crowns I have.

Yonsei Good Day Dental Clinic

Hello. Implants require the entire area without teeth to be filled with gold, requiring more gold material than ordinary crowns. Additionally, gold has properties that can conduct temperature, which may cause increased sensitivity in the gums when consuming hot or cold foods; therefore, we do not highly recommend it. Our hospital offers a material called 'Zirconia', which closely resembles the appearance of natural teeth and is the strongest among currently available ceramic materials. We are providing special benefits exclusively for Cashwalk customers, so if you apply through 'Consultation Request', we will kindly assist you. ^^

Can I still get an implant if my mouth is small?

Yonsei Good Day Dental Clinic

Hello. We ensure that we handle any necessary moments where you might need to open your mouth widely without any discomfort. You don't need to worry too much; if you apply for the event, we will kindly guide you regarding the partnership. ^^
