After a most enthusiastic recommendation from a local friend, I visited Floss Dental for a cracked tooth whilst on a long stay in Koh Samui recently. Dr Grace and Dr Giew from Floss both examined my tooth, took X-rays and made professional recommendations as to options for treatment. At all times they were most attentive, thorough, professional and personable. Their surgery and practices are…

modern, state of the art and client centered. All the staff are supportive, friendly and considerate. Although my stay was not long enough to carry out any of the treatment options their examinations and recommendations will be invaluable to treating dentists when I return to Australia. After my experience at Floss Dental I have no doubt I received the best treatment and advice available anywhere. I will return to Samui where I will definitely seek treatment here in the future.

This is the best dental treatment I've ever had! The entire staff is very polite and attentive. They explain everything several times and consistently double-check the details. The dentist is simply a magician! He treated each of my teeth as if they were a piece of jewelry, taking his time and being very meticulous. The whitening treatment was also very effective. I was pleasantly surprised by the…

I’ve had complicated impacted wisdom tooth removal surgery here. The clinic is clean and neat, great design. Staff is super professional and friendly, surgeon has arrived from Bangkok and also was very professional and friendly. Whole procedure was pretty long ~1,5 hours, but anasthesia was so perfectly done so I couldn’t feel a thing, although my tooth was dangerously located near to the…

I had my wisdom tooth removed at this clinic and I can say that this is the best tooth extraction experience in my life! The clinic itself is very cozy and homey. The staff is incredibly caring and nice. My tooth was removed by a male doctor (unfortunately I don’t remember his name), he performed the procedure very quickly and painlessly, I was even surprised that everything went so quickly and…

the visit was related to teeth cleaning and my retainer on the lower jaw was distracted. unfortunately they don't have an orthodontist for this. but the doctor agreed to meet me and glued me a retainer, and did it well. and suggested clinics that deal with braces. In general, I had good impressions of the work of the clinic. clean, tidy and modern equipment. the amount for cleaning and gluing…

I had a professional teeth cleaning. I'm from Germany. I was thrilled; the staff is incredibly nice and friendly, and the treatment was absolutely fantastic. The dentist was always checking in and making sure I was comfortable. There's a TV above you showing beautiful pictures and videos of Thailand's natural beauty. You also get protective eyewear, and the place is very clean. Everything was…

Everyone knows Dr Grace is amazing at FLOSS, but today I had Dr Giew for a check/clean. He has perfect english, pleasant manner and super gentle. So if you need to book and Dr Grace is full, dont worry and take Dr Giew (male) another great dentist on Samui. No pain after his clean and scale - amazing! And of course lovely Monie to help at reception. Thankyou FLOSS team.

My retainer broke while I was on vacation and I won’t be home for quite some time. This office was able to fit me in immediately and presented all the options for replacement (weighing in price, timeline, and material). Dr. Grace’s transparency sets her apart from so many I’ve seen in the states! Thank you Dr. Grace and team!

My experience at Floss dental office has been truly enjoyable. While traveling in Southeast Asia, I encountered multiple dental problems, leading me to visit multiple different dentists. Without a doubt, this clinic is my favorite among them. ☺️

I liked everything: the pleasant receptionist, the caring Dr. Keo (if I got his name right). I chipped a tooth on the side. They fixed it for 2,500 baht (they put numbing ointment on my gums to give me a numbing injection!, applied lip balm, and there's a TV on the ceiling—the service is top-notch 🔝). In short, I loved everything! …

I had four wisdom teeth removed at this clinic. One of the extractions was very complicated; the tooth was lying horizontally under the gum and had to be filed down in place. However, all four extractions were painless, and the recovery was very quick each time. The doctors make sure you don't feel any pain. My husband also had three teeth removed, and we're currently getting five fillings.…

Everything was also painless and safe, even though he's been terrified of going to the dentist his whole life. The service is top-notch, and everything inside and out is clean and pleasant. There's a TV so your child can watch cartoons while waiting for you. They provide free pain medication and mouthwash. The prices are reasonable. All the staff speaks good English. I recommend this clinic.

A wonderful and modern clinic. I got a filling on my lower eighth tooth for 1,000 baht. The doctor was courteous, polite, and attentive. They speak good English! The receptionist offers slippers and water, which also speaks volumes about their customer-focused approach. I definitely recommend them!
