We welcome appointments and inquiries. Please feel free to contact us before your visit.
SEDATION
Complete your treatment
while you sleep.
Intravenous sedation uses an IV drip to induce a relaxed, drowsy state, allowing you to receive treatment while comfortably at ease. It is an option we offer for patients with strong dental anxiety or a sensitive gag reflex.
*Examination and diagnosis are required to determine suitability. Effects and sensations vary from person to person. Please refrain from driving a car or motorcycle on the day of treatment.
PRIVATE
Your appointment time is exclusively yours
During your appointment, the entire clinic is reserved for you alone. In a completely private room where you never encounter other patients, you can focus on your treatment without worrying about being seen or overheard. Enjoy unhurried, restorative time at our privacy-first hideaway in Roppongi.
