FAQ
1) What warranties or guarantees are offered?
Short: Manufacturer warranties on implants and prosthetics plus the clinic’s aftercare policies.
More detail: Coverage depends on the materials, brands, and treatment plan. Written terms are usually provided at consultation, and regular hygiene visits are normally required to keep coverage valid.
2) Where exactly is the clinic and how do I get there?
Short: It is in Siamscape, Siam Square, just steps from BTS Siam Exit 2.
More detail: From central Bangkok, take the BTS to Siam Station and walk into Siam Square. Otherwise, use Grab or Bolt and set the destination to Siamscape in Siam Square. Parking is also available on site.
3) What payment types are accepted?
Short: Visa, Mastercard, American Express, Diners Club, JCB, bank transfer, PayPal, and cash.
More detail: Bring a physical card and photo ID, and notify your bank about international medical charges before travel to help avoid declined transactions.
4) Which languages are spoken?
Short: English and Thai.
More detail: Most dentists and coordinators are bilingual. Patients who prefer English-speaking assistance can request that when booking.
5) Can I get crowns or veneers quickly?
Short: Often yes, thanks to the on-site lab.
More detail: Many single-unit crowns and veneers can be completed within days, depending on the case. Larger smile makeovers may need additional visits for try-ins and shade matching.
6) How long do All-on-4, All-on-5, or All-on-6 full-arch cases take?
Short: Usually two stages: surgery first and a later restorative visit.
More detail: A common plan includes initial surgery over about a week in Bangkok with a provisional bridge, then a healing period, followed by final teeth on a later trip. Timing varies with bone quality and whether grafting is needed.
7) Do they accept walk-ins?
Short: Limited walk-ins may be possible, but appointments are recommended.
More detail: Same-week slots are often available, but for implants or orthodontics it is better to book ahead so diagnostics such as CBCT scans can be arranged in advance.
8) Are ride-shares recommended?
Short: Yes, Grab and Bolt are among the easiest last-mile options.
More detail: Drivers generally know Siam Square and Siamscape well, and fares are often lower than metered taxis for short city trips.
