Overview of Tsuda Dental Clinic

Tsuda Dental Clinic


We want to be a dental clinic where patients can consult about anything.
What is important for patients themselves to live a healthy life? I think one of the most important things is being able to eat your favorite foods and eat well-balanced meals without any inconvenience. To do that, we need to know the lifestyle of each patient, so we start by listening carefully to what they have to say. We believe that we can help by giving advice and support for health management about not only the teeth but the entire oral cavity. I make sure to spare my time for each and every patient. After working as an oral surgeon at a university hospital in Japan, I went to the United States to study implant treatment in earnest for three years, where I performed treatment. What I learned there was to examine the condition of each individual tooth and examine the entire inside of the mouth to balance the mouth and keep it in good condition for a long time.
At Tsuda Dental Clinic, we will consider the best treatment method according to the patient’s needs and lifestyle. For that reason, we value communication with our patients, carefully explain to them while looking at images of the inside of their mouths, before proceeding with treatment. The atmosphere of the room is calm so that you can relax and receive treatment. We are equipped with the latest equipment to ensure correct diagnosis, and we are particularly strict about sanitation of the equipment that goes into the mouth. If you have any concerns or requests, please feel free to contact Tsuda Dental Clinic.

To ensure that patients receive treatment with peace of mind. We are fully committed to the latest equipment.
We have introduced the latest equipment so that patients can receive treatment comfortably and with peace of mind.
For example, we have prepared tools for patients to understand themselves, such as sharing images taken with a camera on a large monitor and explaining what they are doing while looking at the data. From intraoral scanners, CEREC, examination systems to background music in the hospital, we are equipped with the latest equipment so that patients can receive treatment safely, comfortably, and efficiently.

●A safe environment

We have devised ways to suppress the smell of antiseptic solution and the noise of machines in a warm wood-grain interior so that you can relax and receive treatment.

●Extensive facilities

We have introduced state-of-the-art equipment to reduce the burden on patients, such as reducing pain and shortening time. In addition, we have a system that visualizes the state of the oral cavity so that you can understand the progress of treatment in detail and achieve more accurate treatment.

●Thorough hygiene management

We carry out thorough hygiene management with the world’s highest standard sterilizer.
Instruments and handpieces used for treatment can become with contaminated with dirt and bacteria. At our clinic, we are particular about “hygiene management” and spare no effort in thorough cleaning and sterilization work. The drill, handpiece (handle of the drill that shaves teeth), and 3-way syringe (equipment for spraying water and air) are all cleaned at our clinic and completely sterilized with an autoclave (high-pressure steam sterilizer). In addition, we are striving to prevent hospital-acquired infections by thoroughly sterilizing and storing handpieces one by one in a bag and making sure that they are only opened before being used on a patient. We are also particular about water, and all the water that enters the examination room and the patient’s mouth is sterilized with hypochlorous acid water. In addition, measures against droplet infection are also thorough. We are proud that these thorough measures make our clinic one of the best in Japan.

●Private room

In order to prevent hospital-acquired infections, we have prepared private rooms equipped with the latest equipment such as implants and the latest sterilizers. There is also a safe stroller storage area for mothers and children.
