and prices. Professional team Dr Grace : she is the most patient dentist I ever had , even I was there for regular cleaning ( I don’t think it money making procedure ) she spent a lot of time explaining my gum issues etc. I sent my husband for treatment. She immediately became his fav dentist.

Dr Grace, is very professional and patient. My 7 year old needed a big filling with two injections, he was very very scared. Dr Grace was so patient with him and he didn't even notice when she did the injections because it was painless. Very impressive and very good value for money. Thank you Dr Grace 🙏 …

I strongly recommend Dentist Ms Grace to anyone who needs dental treatments. She has the First Class professionalism and her knowledge in dentistry is superb and commendable. The dental fees charge is also very reasonable.

M. Vutuc via Google 5.0 out of 5
On the first day of vacation, a tooth broke off that held a bridge in the upper jaw, so that the bridge came loose. All dental practises, as well as the dental department at Bangkok Hospital, were already closed. Since the Floß Dental Office was open until 8 pm, we arrived 15 minutes before closing time. When they saw my problem, they wanted to help me. Since the broken tooth was no longer…

r bearable, there was actually only one tooth left to hold the bridge. From a medical point of view, I asked the dentist to try to glue the bridge temporarily. He didn’t want to give me any guarantee that the bridge would last longer than a day. Nevertheless, he did his best and the bridge still holds after a week. Many thanks to the doctor and his team for this sensitive work. They saved my vacation on Samui

I came in with a broken tooth. We didn't have an appointment. They were very kind and squeezed me in. I was very scared, but the professionalism, kindness, and extras of the office took away all my fears. Thanks to the receptionist's excellent work and the doctors' extraordinary expertise, I left happy. Thank you very much for everything!!

I'm terrified of dentists! Today I had a toothache so I called to book an appointment. The schedule was full, but luckily a case became available, so I was able to get treatment. The service was excellent, from the receptionist at the counter to the treatment room. The dentist was very kind and made me feel less nervous. They provided great care and advice, the price was reasonable, and they…
