TREATMENTTreatments
With the bite as the foundation, we support your oral health comprehensively.
Periodontal & Halitosis Therapy
PERIO & HALITOSIS
Gum disease is the leading cause of tooth loss. We consistently support prevention, treatment and maintenance, creating an environment that protects your teeth long term. We also address concerns about bad breath.
Learn moreMetal-Free Dentistry
METAL FREE
Metal-free treatment mindful of the risk of metal allergy. Metal restorations may corrode or release metal ions over long-term use. Using materials chosen for natural beauty and biocompatibility, we support a healthy oral environment.
Learn moreShort-Term Ceramic Treatment
CERAMIC ORTHODONTICS
As an alternative to wire or aligner orthodontics, we offer ceramic treatment that also considers the bite. We holistically refine alignment, bite and whiteness, and in some cases treatment may be completed in a relatively short period (around 1–2 months).
Learn moreWe don’t just treat teeth. We treat the whole body.
The bite is not a matter of the mouth alone.
It may also affect the position of the head, facial balance and posture.
At 369CLINIC, we provide care while valuing not only the teeth but their connection with the whole body.
CASESCase Introductions
We introduce cases of treatment performed at our clinic, such as occlusion therapy and ceramic treatment.

DOCTORAbout the Doctor
Yuki Lee
Doctor, 369CLINIC
A disordered bite can affect facial features and the balance of the body. It may also relate to concerns such as teeth grinding, clenching and strain on the jaw joint.
The joy of biting symmetrically—I want to bring it to as many people as possible. To that end, I continue to engage sincerely with each person’s bite.
Daily self-care is also an essential foundation for protecting oral health.
By helping you master the proper “anti-aging tooth-brushing method,” I hope to support you in keeping your own teeth for as long as possible—avoiding extractions and reliance on implants wherever we can.
To eat, smile and enjoy life with your own teeth, for a lifetime. That is the wish of 369CLINIC, and my mission.

FAQFAQ
Can I visit without an appointment?
We give priority to patients with appointments, but we also accept visits without one. Depending on how busy we are, you may have to wait, or we may be unable to see you the same day. Calling us (03-4500-6939) to check same-day availability makes things smoother.
I'm afraid of pain — will I be okay?
We believe the pain of anesthesia is largely affected by the stimulus of the initial needle insertion. At 369CLINIC, we take care with the condition of the mucosa and the insertion site, aiming to make anesthesia as gentle as possible.
What is the difference between insured and self-pay treatment?
With insured treatment the patient's share is 10–30%, but there are limits on materials and treatment methods. With private (self-pay) treatment, materials such as ceramic and zirconia can be chosen, and durability and aesthetics can be taken into account according to the case.
Can I use the medical expense deduction?
Self-pay treatment costs may qualify for Japan's medical expense deduction. For details, please check with the tax office.
Do you also treat children?
Yes, we also see children. Building correct brushing habits and a healthy oral environment from the baby-teeth stage leads to lifelong oral health. We provide care at a comfortable pace, in step with each child's growth.
Is parking available?
We do not have dedicated parking. If you come by car, please use nearby coin-operated parking. The closest is the lot across from Entsuji Temple; the Akasaka Biz Tower parking is also available.
Do you accept Japanese health insurance?
Yes. We began providing insured treatment in August 2026. We accommodate both insured and private (self-pay) treatment. If you have any questions, please feel free to ask when making your appointment.
