Your coordinator finds clinics that match your needs and helps you choose. Your preferred clinics then send personalized treatment plans and quotes for you to compare.
We set treatment dates that work for you and help arrange your flights and accommodation.
Treatment may take 2 trips to the clinic. The clinic team performs your functional crown lengthening on the first visit. We support you throughout your treatment.
Treatment usually takes 3–6 months and ends with your final crown. Your coordinator stays in touch and helps arrange a follow-up if you need one.

For functional crown lengthening in Thailand, Bangkok and Chiang Mai have equal clinic availability, giving patients a choice between two city settings. Bangkok offers coordinated visitor support, while Suvarnabhumi Airport is about 30 km from the city center, so allow for a transfer into town.
You can usually fly home after 1–3 days, once bleeding is controlled and your surgeon approves. Desk work often resumes in 1–3 days, while strenuous duties should wait a few days. Light exercise can usually resume after about a week, but avoid heavy straining until the site settles. Your final result usually takes 3–6 months, after the gum tissue stabilizes and the final restoration is made.
Swelling, mild discomfort, and minor oozing may occur. A protective dressing may cover the site. You may fly home after 1–3 days with your surgeon’s approval once bleeding is controlled; choose soft, cool foods.
Your sutures, or stitches, are removed as your gums heal, and gentle cleaning resumes. Avoid hard or sharp foods on the site.
Your gum margin, or gum edge, stabilizes, and the final crown or restoration is made after the tissue matures. A routine review checks tissue maturation before the final restoration.
When to contact your clinic: Contact your clinic if bleeding will not stop, pain increases after a few days, or you develop a fever of 100.4°F or higher. For chest pain or sudden breathlessness after a long flight, seek emergency help locally.

Visas for travel to Thailand require a number of documents. The necessary papers can be submitted 90 days before the planned departure. The list of documents includes:
Healthcare is the key development sector of the Thai government. The Thai authorities are convinced that care for the citizens' health should be an absolute priority of state policy and spend about 25 billion baht for healthcare annually.
As a result, 36,673 medical facilities provide excellent medical care in the country. 64 centers in the Kingdom have certificate of JCI (Joint Commission International), the international improver of healthcare quality and safety across the globe. The index of certificates obtained is the largest. To compare, Israel has 20 JCI-accredited facilities, and Germany — only 10 clinics of this type.
The main advantage of Thai resorts is the long beach season. On the east coast and west coast the climate features are different, so take it into account when planning the trip. The best time to travel is during the cool and dry season between November and early April. A large influx of tourists is in March-May, when the air temperature is +30°C.

In the Kingdom of Thailand, hotels of different price ranges and service levels are presented. The level of Thai hotels is comparable to hotels in Tunisia, Morocco or Egypt. Most tourists choose 4 and 5 star hotels with all-inclusive meals. Such hotels have everything for a comfortable stay: varied food, a large well-groomed territory, animation for children and adults. Some hotels have their own water park, which guests can use for free. Budget travelers can afford to book an economical 3-star hotel with half board or no meals at all.
For now, the Kingdom of Thailand requires different visa regimens for diverse states. Some foreigners can stay in the country 60 days without visa control, some of them — only 14 days.
