Important — about this score
Please read before drawing conclusions about this clinic.
This score is an automated, opinion-based assessment generated by SmileJet's proprietary AI algorithm from publicly available information — including aggregated third-party reviews, clinic-published materials, and other open-source signals. It is not a statement of verified fact, a professional medical opinion, or an endorsement, and individual experiences may differ.
How the algorithm penalises scores
Our methodology applies score reductions where signals are detected that, in the algorithm's assessment, may indicate: unverifiable or potentially overstated claims about clinical experience or credentials; review patterns the model flags as inconsistent with organic user behaviour; or limited independent corroboration of marketing statements.
These adjustments reflect algorithmic signal-weighting only and do not constitute an allegation of any specific wrongdoing by this clinic or its staff.

Smile Signature Sukhumvit Dental Clinic is the flagship international patient branch of the Smile Signature chain, located on the second floor of Dhammalert Building at 185 Sukhumvit Road, Khlong Toei Nuea, Watthana, Bangkok 10110. The address sits on Sukhumvit Road between Soi 13 and Soi 15, in the heart of Bangkok's central hotel corridor near the Hyatt Regency and Sofitel. BTS Asok station is the primary transit access point, with exits 1 and 5 serving the building, and BTS Nana is also within walking distance as an alternative. The clinic operates Monday through Saturday from 10:00 to 20:00 and Sunday from 10:00 to 18:00.
Smile Signature operates more than ten dental centers across Bangkok and Phuket, employing over 100 English-speaking dentists and specialists. The chain is ISO 9001:2015 certified, holds affiliate status with the American Dental Association, and received the Dental Service Provider of the Year award from Global Health in 2016. Over fourteen years of ISO compliance covers both clinical quality standards and sterilization protocols, providing documented third-party verification of the infection control and operational processes that international patients increasingly require before committing to dental treatment abroad. The Sukhumvit branch is the network's designated entry point for international dental tourism patients, positioned by the chain as its primary facility for visitors arriving in Bangkok for multi-procedure treatment plans.
The Sukhumvit branch occupies the entire second floor of the Dhammalert Building, providing a larger footprint than other Smile Signature locations. Six modern treatment rooms are equipped with digital imaging and intraoral scanning technology. A dedicated sterilization area with CE-certified autoclave units handles instrument decontamination separately from the treatment zone. The in-house dental laboratory enables faster turnaround on prosthetic work including crowns, veneers, and denture components without the delays of external lab outsourcing. CAD/CAM fabrication using the 3M Lava design system is available for ceramic crown production.
The full service menu covers cosmetic, restorative, surgical, and preventive dentistry. Implant services include single implants and All-on-4 and All-on-6 full-arch reconstruction for patients requiring comprehensive tooth replacement. Cosmetic work centers on IPS Empress porcelain veneers, smile design, Zoom in-chair teeth whitening, and Hollywood smile makeovers combining veneers, whitening, and gum contouring where indicated. Orthodontics includes Invisalign clear aligners and conventional braces. Prosthodontic services cover ceramic crowns and bridges using the in-house CAD/CAM system. Endodontics and root canal therapy, oral surgery, and periodontal treatment for gum disease round out the surgical and specialist capabilities. White composite fillings replacing older amalgam restorations are a routine service.
The Sukhumvit branch is explicitly designed around the international patient workflow. Free consultations with transparent, standardized fee structures are offered so patients can assess costs before committing to treatment. Sterilization fees are included in each visit price rather than itemized separately. Corporate rates have been arranged with nearby Bangkok hotels for patients combining dental treatment with accommodation in the Asok area. The multilingual clinical and customer care team handles English-language communication across every stage of treatment. The chain's network scale means specialist expertise in orthodontics, prosthodontics, implantology, and cosmetic dentistry is concentrated within the Sukhumvit branch and can be supplemented from the broader network for unusual cases.
The 185 Sukhumvit Road address places the clinic at one of Bangkok's most internationally connected transit nodes. BTS Asok sits at the Sukhumvit and Asok intersection, one stop from the major interchange at Siam and connected eastward to the full Sukhumvit hotel corridor. The MRT Sukhumvit station at the same intersection adds underground rail access to the Silom and Rama IX corridors. For patients flying into Suvarnabhumi Airport, the Airport Rail Link terminates at Phaya Thai, four stops on the Silom line from Asok via the Siam interchange. The density of international hotels within a five-minute walk of the clinic means most dental tourists visiting Bangkok can manage their appointments without relying on taxis or private transfers.

My mother broke her braces that very morning. We went there urgently, and the staff took excellent care of my mother. They temporarily repaired her teeth until we returned to France. Thank you again!

This was by far one of the most pleasant dental experiences that I've had in my life! The staff was friendly, knowledgable, compassionate, and made every effort to accommodate my short schedule. I cannot recommend them enough and will definitely be back when something else pops up! Thank you for the amazing treatment and taking care of the pain!

Don't go to this dental clinic! I was asking for a simple deep cleaning of my crowns. Somehow they translated that into wanting to remove my crowns from my mouth and clean the implants and the crowns. I told them that I don't want that done because it will invalidate my lifetime warranty that I have! They asked for everything from X-rays to documentation of the locations of my implants. They completely disregarded me when I told them that I did not want them to do that. I told them all I wanted was a simple deep teeth cleaning. Go to this clinic at your own risk! I would never recommend anyone going there. I hope that this clinic loses all of their future clients as they do not pay attention to what is being asked of them to do.

Decent tooth cleaning and very friendly staff. Hygiene standards are high and the equipment is comparable to European standard. Overall a good experience, I had to wait though because the doctor was running too late. Besides that everything was fine
