Dental services

We provide a broad range of general dental treatments. We will treat you with close attention and care to manage your pain. In particular, our dental clinic has 4 following features.      

One Visit Ceramic Specialists

Latest technologies enable us to complete ceramic treatment in only one visit.

CEREC system is the latest dental CAD/CAM (Computer aided design/
Computer aided manufacturing) system, developed in University of Zurich,
Switzerland. Your new ceramic filling will be mechanically carved out in
approximately 15 minutes, after taking impression with a small camera
instead of using uncomfortable impression materials.  The complete treatment procedure will be finished within 60 to 120 minutes for 1 - 2 teeth. 

Not only the quickness, CEREC system also provides good long-term
prognosis as shown in many studies and patients data.

Normally, between tooth preparation and delivery of the final restoration,
temporary sealing is performed, but during this period reinvasion of dental
caries can easily occur. However, since temporary sealing is unnecessary in our
1-day treatment, we can reduce the discomfort caused after the treatment
due to reinfection.

Our doctors are well trained and experienced for this one visit CAD/CAM treatment.

Professionals in Prosthodontics

Prosthodontics is the area of dentistry focusing on artificial replacements for
damaged, decayed or lost teeth. Your damaged teeth will be designed and
restored back to its original form and function based on this science.

Prosthodontics is the area of dentistry focuses on artificial replacements of
missing teeth. Your missing teeth will be designed based on this science.

Our doctors completed the curriculum of prosthodontics and have obtained
the Ph.D. degree from Tokyo Medical and Dental University. We will carefully
listen to your needs and requests and offer the best treatment plans to help
you regain your missing oral function and esthetics.


Prevention is in fact the best treatment.

We recommend you to participate in CAMBRA (Caries Management by Risk
Assessment) program at our clinic. CAMBRA is an evidence-based program
focused on dental risk management and disease prevention, currently installed
in about 75% of dental schools in the U.S. A simple examination can provide
your own personal dental caries risk and prevention protocol.

This system is a self-experiencing preventive care, and the improved results will be easy for you to recognize, leading you higher motivation towards oral care.

In addition, our clinic adopts a one-hygienist appointed system, meaning that
the same hygienist will be responsible for your oral health care throughout the
course. This makes it possible to carefully observe the progress of each patient, allowing to prevent and care according to patient’s lifestyle, living environment, and life stage.

Pain management

Do you have an image that dentist’s appointments can be painful?

At our clinic, we practice “caries treatment with minimal pain” in order to sweep away those images. We devise anesthesia injections that many people are not
fond of, and perform a pain-reduced treatment by minimal tooth preparation (minimal removal of tooth substance).

Please be assured that at our clinic we will take care of your pain management.



I devised anesthesia injection and are treating a painless little decayed tooth. I will do precise 
treatment so as not to take nerve as much as 
possible and leave natural teeth.

1 day Treatment

Treatment of decayed tooth is completed in 60 minutes in the shortest, 1 day treatment
available. I will make ceramic hoods with less
risk of recurrence of tooth decay.


We are dealing with dentures developed in
Germany called "Konus Krone" which does not use metal springs. I will make a denture that is comfortable to chew so you can eat something delicious.


Adopted the American prevention program
"CAMBRA". We provide "Preventive care that
you can see by eye" adapted to each patient.


We will inform you about general medical
treatment flow. Depending on the state of your mouth and treatment content, please
understand that it may change.
