Our Story
Our Story — The Art of Smile Design
How a boutique Bangkok studio became one of Thailand’s most trusted cosmetic dental clinics.
Cosdent Smile Design was founded in 2014 with one belief — that a beautiful smile can be created for anyone. What began as a boutique smile-design studio in the heart of Bangkok has grown into one of Thailand’s most recognised cosmetic dental clinics, with three branches and a verified licensed dental team. From day one, Cosdent Smile Design has combined digital precision with hand-crafted artistry to give every patient a smile that looks completely natural — and the confidence that comes with it.
“Because a beautiful smile can be created.”
Heritage
A Dental Family Across Four Generations
35+ years of dental practice, passed down to today’s Cosdent Smile Design doctors.
Behind Cosdent Smile Design stands a dental family spanning four generations and more than 35 years of practice. The clinic’s heritage is led by Dr. Oravadee Kiattivejsoonthorn, a dentist of over 35 years and founder of Care Dental Clinic, whose dedication to ethical, patient-first dentistry has been passed down to the fourth generation — today’s Cosdent Smile Design doctors, led by Dr. Daniel. This lineage is why Cosdent Smile Design treats every case with the same care a family gives its own: detailed diagnosis, full digital X-ray analysis, and a treatment plan explained clearly so every patient understands their smile journey.
