Testimonials

I love Dr. Asai! He's been my dentist for probably 20 years now, (since I started losing my teeth)! He is very good at explaining dental procedures, how to prevent decay, how to clean teeth, etc. He gives excellent referrals (to oral surgeons to get my wisdome teeth out, to pediatric dentists for my 4 year old--Young Smiles in Fremont, which I will also review). I drive all the way from San Jose to still see him. Well worth the drive.

The hygenist can be kind of rough, (could have been due to my LONG OVERDUE cleaning), but she did offer some numbing gel.

The rest of the staff is courteous too. They set up your next appointment there or have you fill out a reminder card which they mail so you can set it up around that time.

Highly recommended.

I have been a patient of Dr. Asai's for 24 years. When he took over my old dentist's practice I was scared to death. I have very sensitive teeth. After my first visit I knew I was in good hands. Dr. Asai is very conscious of the comfort of his patients and goes out of his way to make everything is as painless as possible. Dr. Asai is up to date with the latest equipment and practices in dentistry. He has exceptional hygienists also. One, after examining my gums, suggested I get my sugar level checked and saved me from consequences of undiagnosed diabetes. When I have needed periodontal or endodontal care Dr. Asai has provided space for the specialists in his office so I was not inconvenienced. I highly recommend this dentist with his excellent dental and office staff.
