Smile With Confidence

Let our dedicated dental professionals help you achieve a smile that you can be proud of!


Dr. Dennis Nagata performed an implant surgery on my front tooth (#9). The procedure was quick, painless and with minimal bleeding. It was a very positive experience.

Dr. Nagata's implant surgical team is highly skilled and experienced. Dr. Mauri, implant specialist, is very supportive and friendly. Dr. Wesley Sato, D.D.S., extracted my existing crown with ease. I appreciated his calm demeanor.

Thank you, Shannon, for your continued diligence. You chose the perfect color match for my flipper and the flipper fits perfectly... two very important features.

Thanks to Josie for always lifting my low spirits. Keep up being a good assistant to Dr. Nagata.

Thanks to Colleen and Jasmine for their never-ending goodwill and professionalism.

Lastly, I wish to thank Diko (hygienist). She has been very thorough, fast and friendly.

My continual battle for good oral health is finally improving through the efforts of Dr. Nagata and his hard working staff.

With much appreciation,

Masae Choy, Mililani

Frankie and I have known Dr. Nagata since before we were married over 23 years. You are the most professional and kindest people we have been involved with. Thank you for everything. Each person in your office is wonderful and especially caring. Even for me, a most nervous patient. Thank you and aloha!

I must admit, it was a distressing experience to face 2 cracked teeth during the holidays. After it was repaired with your special formula in January, I went to the Big Island to host a birthday dinner. Everything turned our super well and I could speak with confidence. Its been a full 2 months since the repair and it seems to holding up well. Thank you for the prompt and efficient care you and your staff gave me during my distress. That’s what I call excellent service!
