We value “Informed Consent”.

English Page

We believe that the most important thing in dental treatment is building a relationship of trust with patients. Sharing information is essential for that.
At our hospital, we value informed consent, which is taking time of interview and carefully explain about the period and cost of treatment.

Certified as “Family Dentist Functional Enhancement Dental Clinic"

We have been certified as a "Family Dentist Function-Enhanced Dental Clinic" with a full range of preventive treatments that extend the healthy life expectancy.
You can get effective preventive dentistry through insurance treatment.

The emphasis is on chewing correctly.


Proper chewing helps reduce gastrointestinal burden, stimulates taste and touch, and prevents tooth decay and bad breath due to increased saliva.
It is also believed that chewing will increase blood flow to the brain and activate the brain, which will help prevent dementia and aspiration pneumonia.
In addition, increasing the number of times you chew will tighten your facial muscles, which will rejuvenate wrinkles, sagging, and aged mouth.

Careful attention is paid to minimize pain.

Although anesthesia can be used for pain-free treatment, we also minimize pain during injection of anesthesia. Surface anesthesia is performed in advance to suppress the puncture pain of the anesthetic injection needle, and the use of an ultrafine injection needle causes irritation to the pain point where pain is felt.
In addition, by using a cordless electric syringe that warms the anesthesia drug to about body temperature and keeps the pressure constant by IC control, pressure pain when the drug comes in is suppressed.

"We want to support the health of many people through food," and this business opens in this area for 65 years.
