When people get older, they tend to have not only tooth problems but also problems with the activity of the mouth such as decreased function of the mouth and decrease in saliva. We try to improve the QOL of the elderly by safely and reliably providing comprehensive and advanced dental care to prevent mental and physical decline so that they can live actively for all time to come.

Characteristics of dental care

1. Treatment for difficulty of mastication

We provide the treatment for difficulty of mastication by using removable artificial teeth and dentures. Good dentures give patients a purpose of living, or "eating." We will support patients to enjoy meals by providing dentures suitable for each patient.

2. Treatment for oral hypofunction

Oral hypofunction is a condition of decreased oral activity, which leads to unbalanced nutrition and lack of energy and as a result adversely affects the health of the entire body. [1] Food remains in the mouth. [2] It is hard to eat hard food. [3] Time required for eating meals becomes longer. [4] Eating food sometimes causes choking. [5] It becomes difficult to swallow drugs. [6] It becomes dry in the mouth. [7] Food spills while eating. [8] It becomes difficult to speak smoothly, and [9] It is dirty in the mouth. If there is/are any applicable symptom(s), you may have oral hypofunction. In Geriatric Dentistry, we conduct the test for oral hypofunction and provide treatment.

3. Treatment for xerostomia

We conduct tests and provide treatment for patients with xerostomia or Sjoegren's syndrome in cooperation with various departments in the hospital. Oral dryness is treated with massage, rehabilitation, moisturizing agent, etc.
