Smile Signature functions as a specialist-led dental group rather than a general-dentistry walk-in. The Ratchayothin branch offers orthodontics across three systems: traditional metal braces, Damon self-ligating braces, and Invisalign clear aligners, scanned using the iTero digital impression system without physical moulds. Dental implants, ceramic veneers, tooth whitening with Zoom, root canal treatment, and cosmetic dentistry round out the menu. Installment payment plans are available on qualifying treatments.
Take the escalator to the third floor of Major Avenue Ratchayothin and Smile Signature dental clinic sits directly in front of the stairway that connects to the BTS Ratchayothin Station Exit 1 walkway, a layout that makes appointments genuinely accessible without a car. The clinic is also reachable via the internal Major Cineplex bridge at Level 3.
Smile Signature has operated as a dental group for more than 20 years, with branches across Bangkok and a location in Phuket. The chain's Ratchada headquarters holds ISO 9001:2015 full-system certification. The Ratchayothin branch serves patients under the same clinical protocols and specialist team structure.
Orthodontics is a primary strength. The clinic offers three distinct bracing systems: conventional metal brackets, Damon self-ligating braces, which the clinic notes complete treatment faster and with less discomfort than standard systems, and Invisalign clear aligners. Digital impressions are taken using the iTero intraoral scanner, eliminating the need for physical putty moulds.
Dental implant options include single-tooth replacement, multiple-tooth cases, full-arch fixed bridges, ProArch and All-on-4 overdenture systems, and one-day implant procedures. Cosmetic services cover ceramic veneers, Zoom tooth whitening, dental crowns, and tooth-coloured composite fillings. General dentistry services include root canal treatment, wisdom tooth extraction, Airflow prophylaxis teeth cleaning, removable dentures, and routine checkups.
The clinic website is available in Thai, English, and Chinese, and the group maintains an international patients services division. The Ratchayothin branch opening hours are Monday to Saturday 10:00 to 20:00 and Sunday 10:00 to 18:00. Free dental consultations are available. Installment payment plans on qualifying treatments add further flexibility for multi-visit procedures.
