MOS Dental Clinic at Siam Square is an Invisalign Diamond Provider with 25 years of history, Chulalongkorn and UCLA-trained founding doctor, and CT-scan and CAD-CAM technology in a prime BTS Siam location. The clinic is part of the Oracare 30-branch network. Recurring complaints about long wait times, poor appointment management, and specialist unavailability (doctors present only 1-2 days per month) are material concerns for ongoing treatment patients and tourists on tight schedules.

Authenticity

7/10

Rating 4.62/73; below 4.70, no manipulation deduction. Genuine mixed review pattern: generic 5-star majority offset by specific, detailed negative complaints. Organic.

Treatment quality

7/10

Invisalign Diamond Provider since 2016, implants with CT-scan and CAD-CAM. Conflicting filling diagnosis in one complaint. Aligners degrading from extended wear due to scheduling gaps.

Cleanliness

8/10

Consistently described as clean and well-maintained. One off-topic complaint about liquid splashed from window on passerby. Dental environment itself rated positively.

Team

6/10

Named: Dr. Adisorn (founder, UCLA MSc Implants), Dr. Opas, Dr. Jub, Dr. Airin, Dr. Toraphol. Doctors available 1-2x/month at this branch. Poor staff coordination and conflicting advice documented.

Price value

7/10

Invisalign 100,000+ baht noted by one patient. Emma Dong confirms transparent pricing. No upselling patterns. Facebook page as only digital presence limits price visibility.

Tourist suitability

7/10

Siam Square Soi 1, BTS Siam 2 minutes, heart of Bangkok tourist zone. Emma Dong confirmed same-day emergency retainer fix. English adequate. Long wait times are a concern for time-limited tourists.

My dental appointment wasn't as painful as I expected. The dentist was very gentle, and the staff were attentive and friendly. This was my first time using their services. I have a wisdom tooth extraction appointment soon, and I definitely won't go anywhere else; I'll be coming back here for sure. Lots of likes!!!

Terrible service. No follow-up contact whatsoever (regarding orthodontics). And the dentists giving conflicting information about the oral cleaning; one said 3-5 fillings were needed, while another said it wasn't necessary as the decay wasn't that severe. It felt like I was just donating my money to this clinic. In short, I switched to another clinic. The prices are similar, but they offer coupons…

I had a dental implant placed on September 15th, 2024. The doctor explained the procedure in detail, was very gentle, and I didn't feel any pain at all. I was very impressed! 👍 …

❗️Plan carefully before choosing this branch for orthodontic treatment. The staff here is terrible! The clear aligner treatment costs over 100,000 baht, but it's extremely difficult to see the doctor. Even arriving on time, you're made to wait for hours. Scheduling appointments by phone is difficult. The doctor only comes in once or twice a month. If a set of aligners comes loose, you have to wai…

it almost a month for a follow-up appointment. After getting all the aligners fitted, you have to wait over a month to get another appointment with the doctor. You even have to wear the same aligners repeatedly for a month (instead of the usual weekly wear). The aligners are practically breaking down! The staff doesn't coordinate with the doctor, causing patients to wait inconsistently and providing extremely poor service. They really need to improve. It takes a lot of effort to schedule an appointment, waiting in long queues is a huge waste of time, and the service is terrible. I feel completely hopeless when trying to contact this branch.

The wait was extremely long. Anyone planning to come here should allow plenty of time. Even with an appointment, I still had to wait an hour and a half without getting anything done. It's even longer than going to a hospital.
Suthasinee Charoensuk via Google 4.0 out of 5
The doctor provided excellent advice and service, and the assistants were also good. However, the service and queue management have remained the same for years without improvement. It's like many people are lined up at the same time. Arriving 15-30 minutes early doesn't guarantee you'll be allowed in on time. You absolutely need to allow plenty of extra time if you plan to visit this branch.

The doctor is kind, but the wait is extremely long. I waited for hours. I had an appointment at this time, but I was made to wait a very long time.
คุณัญญา ธารใส via Google 1.0 out of 5
This is terrible. I came to ask for treatment for my wound. I called yesterday and they told me to come today. When I came, they said they had already deleted my history. Is that simple and easy? Then what are you going to do with my appointment? This is so sloppy. If you won't give it to me, just say no. That way I won't waste my time coming to your clinic.
Emma Dong via Google 5.0 out of 5
Came here when my fixed retainer broke, they booked me for an appointment same day and fixed it quickly! Very efficient and transparent with price. Great!
