For patients arriving by plane, the journey from the airport takes approximately 17 minutes.

What to Expect During Your First Visit — The One&Only Experience

From the moment you enter, you’ll notice the subtle scent of our signature interior fragrance designed especially for the clinic. Our One&Only Team will take care of you right from the start. While completing your registration form and medical questionnaire, you’ll have time to enjoy a cup of aromatic coffee or tea. Gentle background music and our relaxation room will help you unwind — the perfect place to rest during longer appointments.

During Your Visit

Your first appointment at One&Only Clinic marks the beginning of comprehensive care for your smile and oral health. We start with a detailed medical interview to understand your needs, treatment history, and any existing concerns. Next, we perform a thorough dental examination that includes an assessment of your teeth, gums, oral mucosa, and the function of your temporomandibular joints (TMJ).


Treatment Planning

We use state-of-the-art diagnostic technologies such as digital X-rays, intraoral scanners, cone beam computed tomography, and dental microscopes, allowing for precise assessment of dental condition and accurate treatment planning. If necessary, your doctor may recommend additional examinations — such as occlusion analysis or a consultation with our interdisciplinary team — to ensure a fully comprehensive approach to your care.


Continued Care

After completing the diagnostic phase, you will receive a detailed overview of your oral health, along with treatment recommendations and preventive care guidelines. Our goal is not only to treat existing conditions but also to educate our patients and ensure their long-term health, comfort, and confidence.
