Important — 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 — 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.

Happy Tooth Dental Clinic is a well-established family dental practice located at 99 Hoang Hoa Tham, Loc Tho ward, in central Nha Trang, Khanh Hoa Province, Vietnam. Holding a strong 4.6-star rating from patient reviews, the clinic has built a solid reputation among both local residents and the large community of Russian-speaking visitors who travel to Nha Trang each year for dental care combined with beach holidays.
Often referred to simply as Happy Tooth, the clinic provides a full range of general and restorative dental services, with pricing that is typically described by international patients as two to three times cheaper than comparable care in Russia or Europe. The practice is specifically multilingual, with Vietnamese, English, and Russian spoken by the clinical team, which makes it unusually accessible for foreign dental tourists in Nha Trang.
Happy Tooth Dental Clinic offers a comprehensive menu of general and cosmetic dentistry, including dental implants, porcelain crowns, professional teeth cleaning, tooth-colored fillings, root canal therapy, tooth extractions (including wisdom tooth removal), teeth whitening, and chip and fracture repair. Routine cleanings are priced from around 150,000 VND, and fillings start at approximately 200,000 VND, making it one of the more affordable options in Nha Trang for travelers.
For implant cases, the clinic works with Hi-Tec implants, an Israeli-manufactured system designed for compatibility with the Nobel Biocare prosthetic platform. This gives patients a mid-tier implant option at Vietnamese price points without sacrificing long-term serviceability. Happy Tooth also handles emergency dental visits, which is particularly valuable for tourists who develop unexpected dental problems during their stay in Nha Trang.
The clinic is located on the upper floor of a building in Loc Tho ward and is fitted out with functional rather than luxury-tier equipment. It includes digital dental imaging, sterilization autoclaves, and standard modern treatment chairs. While reviewers note that the decor is more practical than boutique, patients also describe the environment as clean and comfortable, with a waiting area, free WiFi, and water service for visitors.
This practical-over-showy approach is reflected in the clinic's pricing. Happy Tooth positions itself more as a trusted neighborhood dental office than as a premium tourist-branded chain, which is a key reason long-term Russian-speaking residents of Nha Trang recommend it. Infection control follows Vietnam Ministry of Health standards, with autoclave sterilization between patients.
Happy Tooth Dental Clinic is a strong choice for foreign patients in Nha Trang for three main reasons. First, the clinic's multilingual team (including Dr. Tran Thi Nga and Dr. Anton, both of whom receive specific praise in patient reviews) can handle consultations in Russian and English, eliminating the language friction that complicates dental care in many parts of Vietnam.
Second, pricing is genuinely competitive even by Vietnamese standards, without premium tourist markups. Third, the 4.6-star aggregate rating across dozens of reviews reflects consistent patient satisfaction over time. For dental tourists who want reliable, honest care rather than heavy marketing, Happy Tooth is one of the most recommended mid-range clinics in Nha Trang.
A typical visit begins with a consultation and clinical examination, usually supported by digital imaging. Treatment plans are explained in the patient's preferred language, with Russian translation available for the large Russian-speaking tourist base. For simple procedures such as cleanings, fillings, or single extractions, patients can often be treated on the same day, while more complex work such as implants or multi-tooth rehabilitation is planned across multiple appointments within the patient's Nha Trang stay.
Reviews highlight the friendly front-of-house staff, efficient registration, and the down-to-earth approach of the clinical team. As with any dental decision, international patients are encouraged to request detailed written quotes, confirm the implant brand and warranty terms, and discuss lab-work details before committing to major restorative cases at Happy Tooth or any other clinic in Vietnam.
Happy Tooth Dental Clinic is located at 99 Hoang Hoa Tham, Loc Tho ward, Nha Trang, Khanh Hoa Province, Vietnam. The address is in the heart of Nha Trang's central tourist district, within easy walking or taxi distance of most beachfront hotels. The clinic operates Monday through Saturday from 8:00 AM to 6:00 PM and is closed on Sundays. Nha Trang is served by Cam Ranh International Airport (CXR), with regular flights from major cities across Asia, making Happy Tooth a practical choice for international patients planning a dental trip to Vietnam's south-central coast.

I've been looking for a good doctor in Na Trang for a long time. She's a very good doctor, she does everything well and quickly, she's very careful, and she speaks Russian. I got a crown on a very complicated tooth in two days. I often visit dentists in different countries. I'm sure you'll like it here. In two days, I saw that there are a lot of Russian speakers in this office. Thank you ☺️

Six years ago, I had my teeth treated here regularly and left them a small fortune for it. Over the course of three or four years, it turned out that my teeth had been treated incorrectly; everything she had treated that could have become inflamed did become inflamed, and it cost me a lot of money to redo everything.

I went to these dentists for a cleaning on the advice of experienced dentists. They scammed me into getting several fillings, saying they'd soon fall out, even though they were holding up just fine. He ended up doing several fillings, which started falling out after a few days, and then I had to go back several more times because the fillings kept falling out. When I got home, they fell out again, and I had everything done properly at home. I don't recommend this company.

A very cozy and nice place with reasonable prices. They were able to get a filling for me here, even though two other clinics couldn't. And a super cleaning for 250 dong. Thank you, Dr. Phan Van Tam, you're a super professional.

While traveling in VIetnam, two of my crowns fell out, probably from eating a very sticky candy in Hue, and then something too hard and chewy. Luckily, Happy Tooth was a short walk from my hotel. The dentist took care of me immediately and re-cemented my crowns. Weeks later, they are solidly in place and back to normal. Very efficient, friendly, and, the costs were super reasonable.

I contacted Anton Olegovich with a complex problem. The doctor listened carefully, examined me, and explained all the possible treatment options in detail. The procedure was smooth, painless, and discomfort-free. You can tell he loves his job and cares about the results. Thank you again!!!!
