Important โ€” 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 โ€” 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.

Why Choose 66-Dental Clinic in Bangkok?

English-friendly Bangkok dental clinic near Khaosan Road, established in 1982. Run by English-speaking dentists Dr. Preecha and Dr. Wilaiwan with 40+ years of experience. Cleaning, fillings, whitening, crowns, veneers, composite, and same-day emergency care. Recently renovated. Mon-Sat 10:00-18:30.

66-Dental Clinic has been serving patients in Bangkok's historic Phra Nakhon district since 1982. The practice is located at 66 Samsen Road, Ban Phan Thom, Phra Nakhon, Bangkok 10200, in the Banglamphu neighbourhood adjacent to the Khaosan Road area. This puts it within a few minutes' walk of one of Bangkok's most internationally recognized tourist precincts and a short distance from the Grand Palace, Wat Pho, and the Chao Phraya river piers used by tourists exploring the old city. The practice is explicitly presented as English-speaking and tourist-friendly, a positioning that reflects more than four decades of experience treating international visitors alongside its local patient base.

Four Decades of Practice

Founded in 1982, 66-Dental Clinic has been continuously operated by Dr. Preecha and Dr. Wilaiwan, both of whom are fluent English speakers with more than 30 years of clinical experience each. The longevity of the practice and its practitioners means patients are treated by dentists with extensive hands-on experience rather than recently graduated clinicians. Patient reviews consistently note the English proficiency of the team and describe the dentists as experienced, professional, and able to communicate treatment plans clearly to visitors from English-speaking countries.

Services

The clinic provides the full range of general and cosmetic dental treatments appropriate to a neighbourhood practice. General dentistry services include checkups and consultations, cavity fillings, and professional scaling and cleaning. Cosmetic services include teeth whitening, dental crowns, ceramic veneers, and composite bonding work. Emergency dental care is available, with same-next-day appointments noted by reviewers who have needed urgent fillings or dental attention while visiting Bangkok. This responsiveness to unplanned dental problems is particularly valuable for tourists who encounter dental discomfort mid-trip and need prompt attention without booking weeks in advance.

Practical Details

The clinic underwent a recent renovation, updating its facilities while preserving the established character of the practice. Air conditioning, Wi-Fi access, and credit card payment are available. Operating hours are Monday to Saturday from 10:00 to 18:30, with the clinic closed on Sundays. The location on Samsen Road is accessible by taxi, tuk-tuk, or river express boat from the Phra Athit (N13) pier, which is a five-minute walk from the clinic. For tourists based in the Sukhumvit or Silom hotel areas, a taxi or Grab ride of approximately 20 to 30 minutes brings them to the Khaosan Road area.

Who 66-Dental Clinic Suits

This is a well-suited option for travellers who need routine or preventive dental treatment during a Bangkok visit, particularly those staying in the Khaosan Road area or visiting the historic Grand Palace district. The English-speaking team, competitive pricing, and straightforward appointment process make it an accessible choice for unplanned dental needs, minor cosmetic work such as composite repairs or whitening, or routine cleaning that patients have deferred at home. For complex surgical procedures such as implants or full-arch orthodontic cases, the large specialist dental hospitals and clinics further along Sukhumvit are better matched. For straightforward, trust-based dental care delivered by experienced practitioners in a convenient tourist location, 66-Dental Clinic's 40-year track record speaks for itself.

Very nice family owned clinic. Dr. Jenny and her father are incredible and they made us feel welcome and comfortable. My wife had to get her wisdom tooth extracted. We were worried it was going to ruin our vacation but Jenny finished the procedure in about an hour and gave clear post-op instructions. She was so sweet and reassuring. The cost was fair and a fraction of what we would have paid back home. Very thankful for this clinic!

The young, motivated, and cheerful dentist does an excellent job and speaks good English. We had a dental cleaning and a night guard made. We booked the appointment via WhatsApp, and the night guard was ready within a week. Payment can be made in cash or by bank transfer. Same-day appointments are sometimes possible, depending on availability. Gladly again!
